The fuel filter is typically located on the frame rail, near the fuel tank, but not directly *on* the tank itself. It's usually easily accessible and often near the passenger side rear of the vehicle. Look along the frame rail for a cylindrical canister; this is likely your fuel filter. You may need to consult a repair manual or online diagrams specific to your exact model year and trim level to pinpoint its precise location. There might be slight variations depending on options.
