Trying to figure out all of these filters. In Photo 1 I am assuming the large NAPA filter is the engine oil filter. I don't know what the filter to the left of the NAPA filter is. Photo 2 I know is a fuel filter but I don't know if it is the primary or secondary. Photo 3 looks like a fuel filter don't know if it is primary or secondary and it has a what looks like a overflow bag behind it. Confused how that one comes off. Does anything have to be done with the bag? Photo 4 I am positive that is the dryer filter. Is that the only dryer filter?
Thanks John M..
photo 1 is the coolant filter, photo 2 is the secondary fuel filter photo3 is the primary filter and photo 4 is the air dryer. the primary filter is changed by disconnecting the line from the bowl at the bottom of the filter and then removing the filter and the bottom bowl. I loosen the bottom bowl before removing the fi9lter. the primary also has a clear cylinder to the right of the filter that needs to be changed.
RT beat me to the post on this one, if I could just type as fast as Mike talks.

RT, Does anything have to be done with the bag on the primary filter?
Thanks so much!

No that should not need service.
That bag is the puke bag for when you have to prime the filter diesel won't get all over everything.

RT, on the primary system, isn't the piece inside the clear cylinder more of a strainer than a filter? Are you saying it needs to be changed every time the filters are changed?
That plastic bowl can be brittle. It's only plastic just go easy with it
An excellent resource for determining the dimensions and descriptions of any brand filter is the Wix Cross Reference Site:

Here is the page on your secondary fuel filter: http://www.wixfilters.com/Lookup/PartDetails.aspx?Part=145097

I suggest you carry at least one replacement filter (the one with the clear plastic). You can check that and see if you are getting bad stuff in fuel e.g. algae. It is not hard to change. Probably good to carry others as well, but at least that one. If it get clogged it will stop you.
It may not be necessary to change the clear plastic filter each time the furl filters are changed, but you can see if it is looking like there is stuff in it. I just changed my fuel filters today and the clear plastic filter showed some evidence of trash when I took it off and dumped it out there was more bad looking stuff in it than I had thought. It had been 2 years and 20,000 miles so figured it did real good.
Just got mine outta the shop. We had thought that we had algae in the fuel that was clogging the main filter rather quickly, went through 3 of them getting the coach the 200 or so miles from Nac. Turns out it was not algae but the screen which is upstream from the main fuel filter. It was crushed in like a beer can. Unfortunately the old model is obsolete and so we had to install the new version of the screen. $$$
On a recent trip when stopping for the night, noticed a trail of fuel following me. Turns out the filter drain cock crimp failed. Luckily we were near a larger town with a well stocked auto parts store. I now carry a spare of each, a filter wrench and a 1 gallon can of fuel to fill the filters before installation. I also carry a can of quarters for the car wash to remove fuel spray from the wife's jeep. 😬
