Where is the fuel filter on a 1990 Jeep Comanche?

The fuel filter on a 1990 Jeep Comanche is located on the frame rail, near the fuel tank, on the driver's side (left side). It's usually a cylindrical canister-type filter. However, to be absolutely certain, it's best to consult your owner's manual or a repair manual specific to your year and engine. The exact location might vary slightly depending on the engine option.
