Where is fuel filter for 86 Jeep Wagoneer?

The fuel filter location on an '86 Jeep Wagoneer depends slightly on the engine (the 360 cubic inch V8 is the most common). However, it's generally found on the frame rail, near the fuel tank, and often close to the rear axle.

It's usually a cylindrical canister, possibly with a single fuel line going in and out. It might be mounted vertically or horizontally. Because of its location near the fuel tank and potentially under the vehicle, you might need to get under the Jeep to find it. Referencing a repair manual specific to your Jeep Wagoneer's year and engine will be the best way to pinpoint the exact location.
