I found were the pick-up line and the return-line go into a black housing, I think the fuel filter is in the housing. Am I correct?

I think on 04 and newer trucks with V8's the filter is inside the gas tank.

Correct, they are in the tank. I have an 04 2500HD Silverado, and there isn't any fuel filter externally.

i have the 03 sierra denali with the 6.0 and mine is right under the driver's side third door and it isn't covered at all it right on the inside of the frame rail.

in '04 GM went to fuel on demand system and all '04 v8 trucks have the filter in the gas tank(non serviceable). '04 suv's that have the ''z'' engine have an external inline filter.
