all of the below answers are correct depending on what model you have, for the carbureted models with an electric fuel pump it is on the top of the frame rail on the right side next to the fuel pump. On the injected models is is a canister in the engine compartment.
==note to the note==
My 1998 FUEL INJECTED also has the filter on the frame under the vehicle.another perspectiveI have a 1998 Pathfinder and the fuel filter is at the REAR of the car, on the fuel line coming out of the gas tank, held in a clip (to the frame/body) right near the rear differential. Like one other response says, it looks like 1/2 of a pop can, with a rounded end on the tank end and a flat end on the engine side. If you're going to remove it the lines will be stuck on. You might think about clamping off the lines before you remove it, then loosen the clamp, then undo the line on the tank side. Take the clamp (on the line) off, wiggle it like crazy, and it'll come off. Then do the other end. KEEP RAGS HANDY, since gas will definitely spill on you. Use a dab of soap on the nipples for the new filter and it'll slide on really easy. Clamp her up and away you go. Clamp the lines tightly, or it'll leak. AnswerIts located on the passenger side of the engine compartment on a clip attached to the fender well.
