Winn Fuel Filter Gizmo

I've been reading the thread on the fuel-water filter setup on the 90s models. Our 95 300 has an M11 and this is the setup. Would this be the original? When I bought this rig it was bypassed. I had the Cummins guys look at it, replace the filters and hook it back up. They advised me that I was good to go, however, after reading that thread I'm wondering if I can look forward to air in the fuel through the pesky o-rings. Advice? Thanks.

Yes, that is the original set-up.  Yes, it's important to keep the o-rings on hand and replace regularly.

It looks different than the set-up on my 95 U320.
It looks like you have the upgraded fuel filter housing and fuel filter and the original Winn filter.

My original fuel filter has electrical wires running to the filter itself.
I ordered the "newer" conversion housing and a new Winn housing and filter.
It was when I went to install it that I saw that the whole unit had been bypassed just like your unit was.

Have you experienced any problems since you had it re connected?
How long has it been since it was reactivated?

Just had the service done locally and drove it home. Haven't gone anywhere yet. We're leaving in a week or so for Nacogdoches and then on to Oregon. I think for now I'll pick up a nipple to take along so I can bypass it if need be. Guess I should replace the plastic bowl. Thanks.

That looks very similar to the original on my 1996 U320.
My Winn purge pump on mine was seized, so I replaced it with a Racor which has a clear water bowl on the bottom.

The Winn is a good system because you can see air or junk in the plastic "see through" container. If your M11 becomes hard to start, and you can see air in that see through container, air is getting by the "O" rings. Confirm that your purge pump still works before doing anything else to extend the life of this system.

The Winn air leak problem may not be fixed by replacing the "O" rings. The plastic necks at the top and bottom become smaller diameter where the "O" rings squeeze. Remove the see through container and look at the top/bottom necks.
It is not difficult to remove this "see through" container. There is a thumb screw at the top holding the top fitting down. Remove this thumb screw and push the top fitting up, then pull the see through container up and out of the bottom fitting. I pressed short pieces of copper tubing into the top/bottom necks on mine for a permanent fix. I had to make these short pieces of copper tubing the correct diameter by compressing tubing which was slightly too large.

I believe that those Winn "see through" containers are no longer available, perhaps someone else on Foreforums and confirm.

I tried to acquire one  in Las Cruces in Feb. - was told "No Longer Available".  Please advise when you receive them and where you placed the order.  I would like to have a spare.  Thanks.  :)

Here is a picture of the unit on my 95 U320.
I bought a conversion Racor # 12963 so that I can now us a Racor/Parker S3230P fuel filter. I bought this from Diesel Filters.com. for $83.16.

I originally ordered the WINN 300200 filter from Diesel Filters. They called and said they no longer could get the filter but could order it for me from Parker/Racor direct. I believe the price was around $30.
Racor/Parker is in Beaufort, SC 843-846-3200

It looks like you already have the updated fuel filter housing.

Wyatt, Now that I'm looking at the WINN 300200 and the new plastic housing (here on my table), I see how your copper tube suggestion works. I will definitely do this modification, THANKS!

I will try and install all this stuff this weekend an see if it works.
I will take your lead in having a fitting so I can bypass the unit if it gives me trouble.
I will also keep my eyes open for a new water separator/filter system to replace this system in the future.

I am planning on replacing the system on my coach with a  Racor 700 series unit. The 790R30 looks like a good choice to me, the same basic system without the "O" ring issues. Does anyone have any experience with this system?

Recently, I used the information that Dave M provided and ordered/received two of the filters.  Dana is very professional and easy to work with.

Good Luck, Dave A

Someone here fitted that system within the last year or two and was very satisfied. You should be able to find the thread with a search. The shop doing the work tied the old control switches in also. I can't remember if there was also a relocation for better access.

RV Chassis Parts or Oregon Fuel Injection has the clear filters. Those buggers are getting harder to find.
I ordered from Oregon Fuel Injection and they were on back order for months. Got a call yesterday that they're in.

I had already ordered from RVCHASSISPARTS and got them in short order so I canceled the order from Oregon Fuel Injection.

I've experienced the air leak issue at the o-rings. I now coat the o-rings with DOW High Vacuum grease, a silicone grease, and make sure the thumbscrew that holds the assembly together is tight, with an adjustable wrench,  and have not had a problem since. I can't tighten it enough by had to assure no leak.

Several years ago the controller for the Racor went out so it would no long purge, the controller (black thing with buttons) is no longer available. Big problem if you need to change a filter, diesel systems abhor air in the fuel system. I figured out which wire ran the pump and mounted a push button, wired it up and now the pump runs as long as I hold the button down. I don't care anything about the water in fuel indicator light.
I wouldn't mind replacing the whole thing but it's working great and there's too many other things to spend money on.
