The fuel filter is mounted within the left frame rail, and replacement at 30,000 miles is recommended for California vehicles, though not required. Fuel filters on later model vehicles may vary slightly in shape and fittings, so it's important to match the new filter with the old one to ensure compatibility. Before starting, obtain a new fuel filter and position the front end of the vehicle higher than the rear to prevent fuel siphoning. Remove the gas cap and reinstall it after relieving the fuel system pressure. Inspect the hose fittings at both ends of the filter for cleanliness; if there is more than a light coating of dust, clean the fittings before proceeding. Disconnect the push-connect fittings from the filter, and on some models, it may be necessary to remove the fuel filter mounting bracket nut before the filter can be removed. Note the direction of the arrow on the filter, as the new filter must be installed the same way. Loosen the clamp screw and detach the filter from the bracket, then install the new filter in the bracket with the arrow pointing in the correct direction and tighten the clamp screw securely. Carefully connect each fuel line to the filter, start the engine, and check for fuel leaks.
