The air filter part number for my Cummins is Fleetguard AF1838. Actually according to Barry Beam's info it's AF1838M, but I can't find
that number with the M at the end.
I crossed that number with other brands and came up with these;
Fleetguard AF1838
Hastings AF2312
Baldwin PA3951
Donaldson P151097
Wix 42610
Then I went looking at pricing which ranged from $70.00 - $156.00 and found this, which I just ordered;
Amazon.com: Baldwin PA3951 Heavy Duty Air Element: Automotive (http://www.amazon.com/Baldwin-PA3951-Heavy-Duty-Element/dp/B0015RGVO6)
It says they have 3 left!
I got one of the Baldwins for $20.00 plus 15.38 shipping from Amazon
Good deal.
It is an amazing price no doubt, but one of the websites I looked at trying to get more information indicated that that air filter has an inside out airflow direction. That would not be appropriate for our 99'. I would be very careful to make sure that it has wire reinforcement on the inside as well as the outside, regardless of the flow direction.
Don
Don,
I'll compare it with the old one, but my filter housing looks exactly like the one in these pictures;

I haven't had mine open, but the one pictured appears to be outside-in flow, like mine when I checked to see where the inlet is.
All I had was a Fleetguard part number from my owner's manual to go from, and I crossed it on a manufacturer's website. Maybe there's
reinforcing mesh on both the inside and out?
I talked to Baldwin about the air flow issue on that filter. Air flow doesn't matter, wire on both sides well built, I have run them wix and fleetguard.
Great Bruce............ I tried to give you more than one "like" but the system won't allow it.
Thanks, you saved me a phone call in the morning.
We recently learned quite a bit about which are the right & wrong air filters.
Some of which is posted here and pages before & after:
Possible water in air filter? (http://www.foreforums.com/index.php?topic=30332.msg264131#msg264131)
Direction of air flow is called Standard or Reverse and ours is Standard: in the outside & out the end. When I could not buy from our favorite place, I looked around and found an equivalent from a different manufacturer. It had our required metal mesh on in & outer sides, so figured it would be ok for our air flow direction. But after a heads up from another Forum member, I examined it after being in use for several months. I found there were glue/silicone adhesive rings to keep the filter material separated, but this glue was in the inside where if it broke loose, it would be ingested by the turbo.
So direction matters.
What I learned is our Donaldson air filter housing has a label with housing model # and recommended filter. Going to Donaldson web site learned what filter will work and many that will not work. Our filter is on order for our coach from the lowest price seller.
I read the thread about water in the air filter.
In the picture the Baldwin PA3951 appears to have both gaskets, top and bottom. If it looks like it's well constructed with expanded
metal mesh both inside and out I'll use it and I can always drill a hole for the filter-minder if it's absent.
Baldwin is a name brand, so here's hoping.
All of the sites selling that Baldwin number that list the specs show it as being an inside to outside air flow direction. I don't know how (other than maybe not having a metal mesh on the inside, or the glue that Barry mentioned) how these things are made to be uni-directional in air flow, but something to be thoughtful about anyway. I read so much about it in the recent past that it still has me scratching my head. I finally gave up thinking about it... but decided to go with the specifications rather than various cross reference charts.

Traveling man, to remove all doubt Baldwin has great customer service. To ease your mind give them a call thier engineers can answer your questions, that's where I got my answers from as a commercial fleet user of thier products.
I just communicated with Baldwin and they asked me where I got the crossover info, so I sent them this;
http://www.hastingsfilter.com/Literature/Forms/F192.pdf
Under popular air filters, 25th line from top or 19th from bottom.
Baldwins reply; Thanks for letting me know, I will have them update the sheet. Sorry for any inconvenience.
Me; Boy, I wish I'd known before I ordered it. Too late to cancel now. But, I'm glad I didn't install it and maybe ruin my engine!!
Baldwin again; Thanks for checking with us!
Me; I won't be buying your filters anymore. If I were you I'd be sending me a proper replacement at little or no charge and be thankful that I didn't install the wrong one per your website.
Thanks to the forum maybe?........................this sounds reasonable to me;
T-Man,
One of my hotline techs, has forwarded your e-mails to me. We apologize for the error in the printed material and have notified the Marketing department that it needs to be corrected.
If you will take the filter back to the distributor you bought it from and tell them what happened, have the order the correct filter for you if they do not have them in stock. Please tell them to contact Baldwin Filters and we will handle the return (I have already spoke to customer service). If you will please give me the distributor (name, address and state), they will place a note in the database so all the representatives are aware of the situation.
Baldwin Filters takes great pride in our filters, and we sincerely hope that you will continue to use our product.
Sincerely,

I now think we should put little faith in cross-over lists. There is almost NO mention of air flow direction, something we learned on our Forum is very important. Donaldson also just us told us that their web site also has incomplete / incorrect cross info. I am sticking to original brand and model from now on and getting my info from our air filter housing, not even Foretravel listings. BTW, our favorite seller, FilterBarn, switched their main supplier from Fleetguard to Baldwin.
Several years ago Baldwin engineering told me the filter was fine. It also looks like everyone else's cross reference is wrong as well that's interesting?
I have a Fleetguard AF1838 from Filter Barn I installed 2 years ago. With all of this discussion going on, I started reading like you all and realize how confusing the information on cross ref. is out there. When the time comes to replace the filter, I will check my container on my coach for the correct number, then cross ref on Filter Barn, followed up with a call to Baldwin if needed to be sure I get the right filter. I agree with everyone that the air flow makes this much more confusing than it should be ( at least that is my opinion).
Maybe the suppliers need to realize we need KISS information. ^.^d
I took the easy road and bought the Donaldson air filter recommended on the container. From now on, when it comes to air filters, no more cross for me. Even found a good price on line. Too many manufacture techs don't understand the enounces of their many air filter part numbers. Just too easy to say it is exactly the same size and they look alike so they should be interchangeable, without knowing all the details.
Teresa,
I contacted Nelson petroleum (the vendor) and luckily the filter hadn't shipped, so they agreed to cancel my order and have Amazon refund my money.
Given all the confusion associated with crossing filter numbers between manufacturers I think I will stick with OEM filters from now on. In this case it's a Fleetguard AF1838.
I appreciate your offer of a correct Baldwin filter replacement, but to be honest I'm hesitant to accept it due to the fact that the dimensions of your PA2660 and the AF1838 are dissimilar, as can be seen by comparing these two links;.

Thank you,
T-Man
FYI: Filter Barn isn't going to carry Fleetguard once their stock is exhausted. They are replacing it with(you guessed it) Baldwin.
I just looked at the Donaldson filter canister label on the bottom for a filter number but there is none. That box is blank.
So I'm going with what my owner's manual says........................Fleetguard AF1838.
This is a bit off-topic, perhaps. About 15 years ago, one of the first things I did to our U270/Cummins 8.3 was to install an airfilter that is cleanable. The instructions said to "recharge" when the air restriction is 25. I have never seen that value. I clean it with garden hose pressure, let the element dry, then recharge the oil with a $12 package, from most any autoparts place, and then good to go. I have done this twice in 15 years. Easy to do. Easy engine starts. Everything seems okay doing this for 70K miles. Andy1

T-man that's what I currently have in mine. As I said over the 12 years I've had the coach I have run Baldwin, Wix, and FG with no issues ( confirmed with oil sampling)
Bruce I just looked up the Donaldson P18-8043 which crosses to the AF1838 and the specs indicate that the Donaldson is almost
1" shorter than the Fleetguard. In fact I cannot find one other cross that has matching dimensions to the AF1838.
I just contacted Cummins here in Ft. Myers, FL and they told me there are no AF1838's available anywhere around the state.
The problem is that I don't know what filter I have now. Guess I can open the canister up and have a look, using a tape measure and hopefully find a part number somewhere.
Talked to tech rep at Fleetguard and after a 5 minute wait he confirmed airflow on AF1838 as outside-in. However his CAD drawing or whatever he was referencing didn't show expanded mesh on the inside. When asked about flow direction he said the filter media didn't make the difference, only the placement of the expanded mesh.
So with mesh on both the inside and outside the filter is bi-directional???
I would think so, the filter media shouldn't have different properties on each side and would filter the same in or out. I am not an expert in physics so this is my opinion.
Some filters are spec'd to have additional different filter material on air input side, so there are no one size fits all when it comes to truck air filters. That is why it is so difficult to get equivalent cross references, especially so when considering lower cost material and construction models. Air filters have a job that oil filters don't have. Oil is closed system. Air is bringing in outside air with all of its possible junk.
I just spoke to Cummins in Knoxville, TN and was told that the AF1838 is $100.66 and unavailable.
Does anyone have one of the other filters that crosses with the AF1838 installed on their FT that feels confidant that it is
the right fitment and the right flow direction? If so I'd really like to get the part number from you.
Thanks

Just looked them up try simplyfilters.com less than 90.00. The FG is 28.90 long Wix 42610 is shown to be 29.00 not enough to bother any thing IMHO ( I have run them ).But as always do what makes you feel right.
The best thing to do ,is get the filter housing number, call Donaldson and get the correct filter. ^.^d
Wix tech told me yesterday that the Wix 42610 is inside-out flow.
I just went out and checked our filter housing, this is on a 97 U270.
Filter housing #ECG 11-2001.
Filter #P14-8043.
I found the P14-8043 on E Bay for $47 and change.
Like the late Dave M would say, do what makes you happy.
Just looked at mine on the 92 with a Detroit only difference was ecg-2001 main element P14-8043.
Baldwin PA 2732 air filter
Says it's inside-out air flow; http://catalog.baldwinfilter.com/PartSpecificationPrinterFriendly.asp?partnumber=PA2732
I guess I'm in the same boat
The whole thing is nutz!
Could that possibly mean that the flow could be either direction? Just asking
Yep sure is. And to add to it theDonaldson # is .90" shorter than all other filters that it crossed to. All I know is I have a FG in mine currently shows 10 on the filter minder so I must be working.
Maybe, but I can't find out for sure.
I'm probably going to go with the FG. Planning to open mine up in the next couple of days to see what I've got now.
My 2 cents worth knowing what I know I would not put anything in but the Donaldson blue filter, yes it is more money but worth it to me.
After all the research and different filters our coaches take if anyone does think they can "ask a mechanic" then I have some land for sale.
After reading this thread with air intake inside out outside in, all the different brand and part numbers mentioned I started going crazy wondering what I had, was it the correct one, should it be air inside out outside in, have I been damaging my engine. Geez it's just an air filter give me a break. So I dug out all the information I had on our coach and found this one document from August 13 1993 that specifies an AF954M (Fleetgard) part number. Scrambled outside to see what I have. AF954M by Fleetgard. Good enough for me I don't care which way the air is flowing. Sometimes I should leave some threads alone.

Response to John on Donaldson Blue:
From Donaldson Tech:
"We also discovered an error that crept into our part detail on our website that showed a standard media element and Donaldson Blue element as alternate parts for the correct filter for your G112001. They aren't alternate parts, there's just one filter element for G112001 - P148043."
X2 Roland
Forget pricing................................I have narrowed the filter choices down to either a Fleetguard AF1838 or the Donaldson P148043 as they both are standard flow (outside-in) and have proper fitment.
Thanks everybody, especially Barry & Cindy.
There must have been another thread going on about this filter stuff as I remember saying in one about a month ago that the Donaldson P148043 is the correct one in a lot of cases. I really cannot understand why anyone would try to save 10 or even 40 $ shopping around with other makes when the cost of an engine is so much more. What are we talking about in real terms- case or 2 of beer??? how much did you spend buying the coach??
JohnH
Switched to Donaldson blue tec woven foam for more power and finer filtering after I saw them mentioned on Pittsburg powers web site.
The donaldsons site shows the difference of the dirt removal differences and its quite a dramatic difference. More power is nice also
Hope this doesn't apply to you Bob;
From Donaldson Tech:
"We also discovered an error that crept into our part detail on our website that showed a standard media element and Donaldson Blue element as alternate parts for the correct filter for your G112001. They aren't alternate parts, there's just one filter element for G112001 - P148043."
I noted that statement as well, and want to thank Barry and Cindy for their relentless pursuit of the correct part.
I do wonder what the difference is between the blue and standard media filters, other than better filtration. Could it be that the blue doesn't ship with proper gaskets? No filter minder hole in end plate? Different size?
Yesterday I ordered a Donaldson P148043 for a price that is about two cases of beer less than Fleetguard's AF1838, and more easily obtained.
That is my assessment... The Donaldson - DBA5029 has the correct air flow direction, has the right dimensions but lacks the small end gasket and the filter minder hole. As far as filtering the air goes, my judgement is that it fulfills the requirements provided the cover compresses the big end gasket enough to seal properly without the additional foam gasket on the small end which is there to provide a seal to the filter minder port. With no hole there, the filterminder fitting would not be on the vacuum side of the air flow. I had ordered the DBA 5029 before Barry's reply quoting a Donaldson tech. I haven't put it in yet, but I will assess the fit and whether or not to add the small end gasket for extra compression. As to the filterminder hole, I could use an appropriately sized punch with a length of 3" ABS pipe as an anvil to add one, but as I don't think my filterminder is working properly anyway, I won't bother. I will however look at adding a filter minder fitting elsewhere on the low pressure side of the turbo so that (assuming the DBA 5029 passes my fitment assessment) so that I can have that functionality after I get a new filterminder.
I will post about it when I get around to doing it, but of course anybody considering doing likewise will have to trust their own judgement.
Don
Don,
Because our filter is axial sealed, it needs gaskets on both ends. Sure the hole is only for monitoring so not required for filtering. I assume that just cutting the gasket off the old and gluing it on the new will suffice. Even if it feels tight, I assume it still needs the seal of a soft material.
FROM DONALDSON
Regarding construction of the P148043; yes, it's an axial seal, pleated filter element so it features steel end caps with a rubber gasket on both ends. There's an inner liner of stretched steel to support the media. A bead of glue around the circumference of the media forms a pleat lock to inhibit movement in the air flow path. The outer stretched steel liner provides protection of the media/pleats during handling.
T-man, well done on saving. My point on the comment I made was that many members (in my assessment) were trying to save this amount when purchasing a filter they thought would do the job, only to find now that they should be looking on getting the proper one for engine and NOT just looking on saving money with something that fits the "can. !!
JohnH
John,
I just hope the right filters don't become unobtainable because those new plastic filter housings look difficult to retro-fit. Now that
the Fleetguard filter may no be longer available from Cummins I'm hoping Donaldson doesn't follow suit.
As far as I know, Fleetguard still makes and sells their AF1838 air filter.
I think the story is that Fleetguard decided to not sell to FilterBarn because FilterBarn was selling at prices lower than Fleetguard's national customers, so FilterBarn switched their main supplier to Baldwin.
The AF1838 is available but at much higher prices.
Below is Fleetguard's current catalog page for AF1838 and the Donaldson cross reference.
Also below is Donaldson's descriptive on our air filter housing and all parts available including the plastic nuts.
just bought the Fleetguard AF1838 off Amazon, about $110 shipped.
I understand that others are selling Fleetguard AF1838's but I can't seem to get one through Cummins, and isn't Fleetguard Cummins?
It is or was owned by Cummins.
T-man Cummings usually doesn't supply the air filter with the engine in most applications, the engine purchaser does( kenworth, Pete, Foretravel, and so on) . While Cummings may own FG as engine dealers they don't stock the filters usually, as most users buy in the aftermarket.
Well after reading the long thread I had to remove my air filter to see what was in it. Surprise LAF 9396 I checked where it contacted the housing on both ends and it matches. It has a hole in the center and metal on inside and outside. I replaced the filter with the numbers of the one I removed. I can only guess that it was put in at Immaculate Coach Works as Ron the previous owner before the person I bought it from serviced it at his shop. When checking it against dimensions of the Fleetguard 1838, it is a little longer and a little wider, but it makes contact where it should and is not mashing out the rubber on both ends.
I will have to really think this one out before I use the coach again. Physically I see no reason to not use it.
Crane,
When we could not buy our favorite Fleetguard air filter from Filter Barn, we purchased your LAF 9396 from Amazon.
Based upon another forum warning that his LAF 9396 failed and caused an engine rebuild, I took a more detailed look at our 9396. I found the glue that holds the filter element from moving to be located INSIDE the filter, and some glue was missing. Glue that breaks loose will move into turbo. Nothing should be on the outbound air side except for the wire screen keeping the filter in place. This filter may be better designed for Reverse air flow.
I also felt maybe the element material was not as sturdy as the Fleetguard.
From all the discussion and research I decided to buy the original Donaldson part number, which is being delivered later today. And my 2-month old LAF 9396, next home will be the trash bin.
But I would have no hesitation about using the Fleetguard cross AF1838 that I used for about 20 years without a problem. I just found the Fleetguard prices to be higher.
Donaldson at Ryder is $46.16 + $7.95 shipping + $3.58 taxes, total $57.69. Ryder sells the Donaldson filter as a special order, which ended up taking 2-weeks which is ok, but it could have taken 4-5 weeks.
I will be studying to see if it has that issue. I have used Luberfiner filters for my crane oil, fuel and air for 30 years no problems. Curious how the filter failed to cause engine rebuild. It appears the inner screen would prevent any glue from migrating to the inside.
I believe this is the previous discussion AIr Filter Failure Warning! Don't get Dusted! (http://www.foreforums.com/index.php?topic=25391.0)
If not, let me know and I'll delete this post
There is no inner screen on that failed filter. The laf 9396 has an inner screen. It must have been a different filter. I believe Barry stated it was on another Forum
Looks like Michelle found the reason for the air filter failure, so let's feel that Lubrifiner air filter quality is not at question anymore. But I do feel that the other posting from Crane is not consistent with my Lubrifiner filter. While the inside screen will likely keep filter material in place, the silicone type glue ring is not protected from being sucked into engine. Our own filter has breaks in the glue and we wonder where the missing glue is. When we get the filter out, I will take a photo of what I see inside our Lubrifiner air filter. I do not think the glue ring is quality issue, it just makes me think this type of construction is designed for Reverse air flow.
If it is for reversed air flow they shouldn't have put a hole in the center cap on the end for the filter minder. It would do no good if it was reading the incoming air. However stranger things have happened.
Donaldson air filter arrived from Ryder and photos are below. I cleaned out filter housing which was pretty clean, tightened ever air flow clamp from air intake to filter, to turbo, to intercooler, to intake manifold, (all were pretty tight).
Put on new cover gasket, installed Donaldson air filter, and we are good to go.
Looks good Barry.
Comparing the new Donaldson P148043 to the 2-month old Lubrifiner LAF-9396, we see they are both made pretty much the same. Both weigh about 5 lbs and look alike.
Photos below have the Donaldson on the left and the Lubrifiner on the right.
Both have wire screen on in & out sides, have small end hole, came with cover gasket and both have similar spiral glue rings on inside.
I now yield to the group and have backed down on my previous negative feelings about Lubrifiner, and withdraw my incorrect statements.
This is our first Donaldson filter and was surprised to see the soft glue spiral ring on the inside. I am not sure how the Fleetguard AF-1838 that we used for many years before buying the Lubrifiner, is constructed.
FYI, the Donaldson attached closed-cell rubber filter end gaskets and the loose cover gasket is made a little nicer than the Lubrifiner and Fleetguard, which look like open cell foam.
We now understand that filters are designed for Standard or Reverse air flow, and our next filter will probably be Donaldson or Fleetguard, both of which are cross-referenced. But there does not seem to be any reason to not also consider Lubrifiner. All three of these look alike, have in & out metal screening, small end hole and loose cover gasket. Other manufacturers may have similar offerings, but I have no experience with any others, so I will just stick with the above three part numbers.
I questioned Donaldson about the sealant bead on the out-flow side of the air filter and this is their reply:
"We've been applying inner beading on our air filters for nearly 50 years. I've never heard of any problems of the glue bead breaking down and entering the engine.
P148043 is the filter that ships with all brand new G112001 air cleaners and is the correct replacement element.
The inner and outer beading provides support to the pleats against flexing in the air flow stream and holds the media securely against the inner liner."
For years we mainly used Fleetguard AF1838 air filter, but at that time, did not know enough to examine the filter closely, so I don't know if the Fleetguard has inside beading. If anyone is now using Fleetguard AF1838 and is opening their air filter housing for some reason, could you please let me know if the Fleetguard has inside glue spiral beading, or if it is only on the outer side.
The 4th photo on a previous above posting shows the inside bead on the Donaldson.
I ordered the same filter as Barry, the Donaldson 148043. The existing filter is a Fleetguard AF954M, the same one as Roland's. Looks OK. The air cleaner can calls for the 148043. A Cummins dealer installed the above Fleetguard but I am suspect of their work and figure I'd just go with what the air cleaner calls for. I was also missing one of the plastic nuts that hold the end cap on so I picked up a new set of those too. Hated to see that mismatched nut! I wanted to replace the gasket for the end cap but wasn't able to locate one.

Don,
Did you ever order the Donaldson DBA5029 air filter? Did it have the gaskets on both ends, and the air minder small hole?
|
Dan,
$66.86 here
http://www.filterspro.com/detail_2.cfm?part=2671719
Roger
Thanks Roger.
It was unclear from previous threads if the blue DBA5029 comes with the gasket on each end of the filter, and if it has the air minder hole in it. Have you purchased this filter w this number? (I read the debate about air flow in/out and the bLue model number debate)
I'm between ordering the standard Donaldson P14-8043 from Ryder $46.16, or the blue one. It's not the cost difference concerning me, but whether the blue has the 2 gaskets attached at each end and the filter minder hole like the standard filter does. I plan to order ASAP so it will get my location before we move on down the road.
Thanks!
Dan, see the email from Cummins that I forwarded to you. The 5029 should be the right one.
Roger
It did not come with a gasket on the small end and has no hole for the filter minder. My filter minder wasn't working properly anyway, so I just removed the small end gasket from the old filter and glued it on to the new one just to make sure that the compression would be the same (though I suspect it would be adequate without the small end gasket) and am doing without the filter minder for now. I plan to replace the filter minder and at that time I will revisit the the choice of filter. One option would be to relocate the filter minder suction source elsewhere in the intake piping and plugging the hole in the filter housing cap. I haven't decided as yet.
Don
I know this is an old blog here, but thought I would post here instead of starting a new one.
I decided to change my air filter as it had been 3 years since before and when I pulled the filter that MOT had replaced, it was a Fleetguard 1837. Not sure what the difference is between the 1837 and the 1838, but now, I am wondering???
I ordered a Donaldson P150694. It did not come with the small hole in the end for the filter minder, so I punched one in and it did not come with the small end seal, so will add that as well. With all the discussions on here in the past 6 to 7 years, it was so confusing on inside, outside, vs outside in, I'm lost, which is about right! Now, I am afraid to install this new filter without posting my confusion and frustrations! Help is required! Thanks in advance!
So, you have to see if the dirt collects on the outside or inside of the filter. Ours brings the unfiltered air in to the filter housing and then sucks it though so the ourside gets dirty. When we bought ours, you could not see the filter as it had never been changed in about 60K miles.
I just used an icepick, hitting it with my hand to punch the hole. I took a razor blade and went between the filter and the gasket until I had gone all the way around.
My old posts show the process.
I glued it on with silicone.
Works like a champ.
Pierce
X2
Don't forget to inspect or just replace the vacuator valve. Its old. Clean all the dirt from the inside of the filter housing being careful to not permit any into outlet towards engine. 🐿 I also like to put a little silicone grease on seal. Last time I tried to order the preferred blue filter they had been discontinued
Scott
Pierce, it collects on the outside of the filter. MOT installed a Fleetguard 1837 and I can't find it in my search. I ordered the Donalson filter, but also can't find where this was the correct one or not! Donaldson P150694
Scott; I ordered and replace that vacuator valve and also the new filter. Just want to make sure that is the correct filter for our application. Donaldson P150694 is what I have now to install. Had to punch a hole in the small end for the filter minder and will have to add the gasket that was on the Fleetguard to the new one to make a good seal. There are many threads on this and it got really confusing to say the least with filters. Just don't want to make a mistake!
Joe, I think your coach takes a Donaldson P14-8043. You might check the tag on the bottom on the air filter can to confirm. That filter comes with the gasket in place, small hole, and cover gasket
Bruce, I looked but did not see a tag! It seems I can't find that filter either, but will look again, thank you!!
Found that part on Amazon and will order it. Thanks again!
Joe,
I bought a Donaldson Blue from a Forum Cummins owner. He measured it and I compared it to our existing filter. They were the same so I had him send it. Easy R&R. So, check the number from my post and other Cummins owners here on the forum. I'm going to be due for a change next year so will pick up one soon.
GV owners should check theirs much more frequently as the filter sucks in everything the rear wheels throw up. Foretravel finally ran a big tube across the side radiator and up a foot sometime in 1993 to cure this engine duster. Probably the worst idea for an air cleaner intake in the history of the world.
Joe, just make sure to measure the length so it matches the old one and with the rubber gasket, you will feel the gasket when you push on the end cover secure it and then tighten the four nuts. I installed a new restriction gauge so I glance at it when checking the oil. It records the highest reading but if driven the the rain or fog, it may record a higher restriction so should be reset and driven before changing the filter. Detroits, Cummins and CATs all have different maximum restrictions so look at the chart
Photo #1 shows what the Roots blower and turbo do to a damp/wet filter.

I should have mentioned that the Donaldson blue construction is vastly better than the Fleetgard or Wix. One member lost a $30K engine (dusted) because of air filter failure.

Pierce, I went on the Donalson website and when I plugged in the DBA 5029, nothing came up in the search. Has the number since changed? I would really like to do the blue if possible!
I was told by a 3rd party that they had discontinued it.

My last change I used this filter (following). Has gasket for both ends and the hole for filter minder. Dirt collects on outside, clean air to engine from inside. Donaldson P148043 Filter
Checked it this week. Outside loaded with dust/dirt, inside clean. Cleaned the housing, ordered new filter. Filter minder was still OK, but I am changing it.
And I just ordered a new one, now double the price from 2 years ago. Amazon.com: Donaldson P148043 Filter : Automotive (https://www.amazon.com/dp/B00KNIW74Q?psc=1&ref=ppx_yo2ov_dt_b_product_details)
