Just purchased new fuel filter for 2004 Silverado. Dealer gave me the same filter that my 2000 Silverado uses, but can't find the location of the filter on the 2004. It is not on the frame rail like 2000. Traced lines from tank and they go in and out some kind of box like arrangement mounted above the driveshaft forward of the differential and straight to the engine. No filter in sight that looks like the one provided by the dealer. Hoping they have not decided to mount it inside the tank. Anyone experienced this yet. Have 4.8 L v-8 standard cab.
