Where is the fuel filter located on 2004 Chevrolet avalanche 5.3 liter?
On a 2004 Chevrolet Avalanche 1500 with the 5.3L engine, the fuel filter is located in the fuel pump module inside the fuel tank. This means it's not accessible without dropping the fuel tank. It's not a user-serviceable item that's easily replaced like some older vehicles; it's usually replaced as part of a fuel pump assembly replacement.
