I have the same chassis but with a Cat C-7 engine. I hav e two fuel filters, one at the rear of the coach, Wix 33434. Easy access. Also have a second filter that high on the side of the engine near the injector pump, Wix 33626. This one is much harder to access. I have to remove the access panel under the bed to even see it. I’m able to reach it from this point but sure isn’t easy. Both are screw on filters.

Good luck,
