The fuel filter is located on the right frame rail; you can find it by tracing the fuel lines to the canister filter. To help relieve any pressure, remove the fuel cap and be sure to have a container available to catch any fuel when removing the filter. Make sure there is no damage to the O rings prior to installation. After replacing the filter (tighten the fittings to 18 lb ft) follow the following procedure to ensure there are no leaks prior to starting the vehicle.
Turn ON the ignition, with the engine OFF, for 2 seconds
Turn OFF the ignition for 10 seconds
Turn ON the ignition, with the engine OFF
