Am planning to take a trip this coming Spring and since I have never changed the fuel filter thought it was about time. Was told there were 2 filters [?] and needed to see which one I had.

Please do not tell me to go to the G.M. dealer/service for assistance. Tried that already and was informed that they did not work on or service "Workhorse" and more and should go to RV dealer.

Was able to find a # but not locate the filter.

Thanks in advance for any and all info can be provided.

Try inside the frame rail, passenger side, behind the front wheel.

OEM-Engineering is the source for the filter.

Well there is one in the tank-some times called a "sock" but it onlt keeps water out of the system. There should be one tucked in the chassis rail about mid point. Best to say follow the fuel line from the tank to the engine and you will find it. On our older none fuel injected engines -pre 1990- there is a small one inside the carburetor its self.

HERE's another source for the filter and adapter. Scroll about half way down the page.

You tube it with year, make and model. Good luck, let us know!

IF your 2007 is a W series chassis, the fuel filter is in the DRIVER side frame rail just above the rear axle. Most likely you will need to purchase the adapter kit as shown in the link provided by PAZ, above.

There is NO filter available that has the two outlet ports, and that is why you MUST by the adapter that allows the use of a standard filter, which comes with the adapter.

To follow up on what I posted previously and on what Ed said, if there is already an adapter in place, you only need to buy the filter. Look for the filter along the frame rail as described by Ed. The original filter and adapter were all one. If you already have a separate adapter, the GF481/652 (or equivalent) fuel filter is available at any auto parts store or even at Walmart.
