I believe your coach is on a Freightliner chassis. If you take your VIN to a Freightliner dealer, or even call them, they'll give you the part number and sell you the filters. You can probably find them for a few dollars cheaper, but I find it easier to get them straight from Freightliner.

Many will tell you to just change them, then turn the key on several times. I had issues doing that and will never do it that way again. I take off the primary and fill the new one with clean fuel. When filling the filter, plug the center hole and fill the filter around the edges. I like to then turn the key on several times, allowing the fuel pump to top off the filter. I then start the coach and let it run for a few minutes.

Once it's running well, I take off the secondary filter, fill the new one and reinstall. Turn the key on again, allowing the fuel pump to top off that filter.

Some coaches come with a pump near the primary fuel filter. It often has a rubber cap on it. Remove the cap and pump it like an old Coleman lantern and until firm.

My way of doing it may be overkill, but once you have an issue with installing dry filters and the coach not starting.....panic can set in. I've been changing mine this way for 17 years.

Easiest way to get the part numbers is off the current filters. You can cross reference to a different brand filter if you like via Google, Or NAPA or any Cummins or CAT shop can.

I use Donaldson filters.
NAPA store brand are built by a major filter maker.
