Fuel Filter: Service and Repair

REMOVAL

CAUTION: If the fuel filter is being serviced with the rear of the truck higher than the front, or if the tank is pressurized, fuel leakage or siphoning from the tank fuel lines could occur. To prevent this condition, maintain the vehicle front end at or above the level of the rear of vehicle. Also, relieve tank pressure by loosening the fuel fill cap. Cap should be retightened after pressure is relieved. If vehicle is warm, change the fuel filter before the pressure rebuilds.

1. Shut engine off. De-pressurize fuel system by depressing the schrader valve in the fuel rail. Use caution to prevent combustion from fuel spillage.

2. Raise vehicle on hoist.

3. Remove push connect fittings at both ends of fuel filter. Install new retainer clips in each push connect fitting.
