Fuel Filter, In-Line

 CAUTION: If the fuel filter (9155) is being serviced with the rear of the vehicle higher than the front, or if the fuel tank (9002) is pressurized, fuel leakage or siphoning from the tank fuel tubes could occur. To prevent this condition, maintain the vehicle front end at or above the level of the rear of vehicle. Also, relieve fuel tank pressure by loosening the fuel fill fuel tank filler cap (9030). Fuel tank filler cap should be retightened after pressure is relieved. Depressurize the fuel tube system at the Schrader valve on the engine fuel injection supply manifold (9F792). If vehicle is warm, change the fuel filter before the pressure rebuilds.

Removal

1. Shut engine (6007) off. Depressurize fuel system. Refer to Fuel System Pressure Relief in the Service Procedures portion of this section.

2. NOTE: When the battery (10655) is disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) (12A650) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.

   Disconnect battery ground cable (14301).

3. Raise vehicle on hoist. Refer to Section 00-02.

4. Remove filter-to-fuel tube retainer clips.

5. Remove push-connect fittings at both ends of the fuel filter as described in Push-Connect Fittings, Steel in the Removal and Installation portion of this section.

6. Remove two nuts from filter studs and remove fuel filter bracket (9A335).

Installation

1. NOTE: Note that the direction of the flow arrow points to the tab of the fuel filter bracket against which the fuel filter rests.

   Install fuel filter assembly and two nuts. Tighten nuts to 8-10 Nm (71-89 lb-in).

2. Install push-connect fittings onto fuel filter ends as described in Push-Connect Fittings, Steel in the Removal and Installation portion of this section.

3. Snap on filter-to-fuel tube retainer clips. Long legs of clips go onto fuel tubes.

4. Lower vehicle and connect battery ground cable.

5. Turn ignition switch (11572) from OFF to RUN position several times without starting engine. Check for fuel leaks.
