Important: Inspect the fuel tank internally and clean the fuel tank if you find a restricted fuel filter.

1. Relieve the fuel system pressure. Refer to the Fuel Pressure Relief .
2. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
3. Clean all the fuel filter connections and the surrounding areas before disconnecting the fuel pipes in order to avoid possible contamination of the fuel system.
4. Disconnect the threaded fittings (1) from the fuel filter.
5. Cap the fuel pipes in order to prevent possible fuel system contamination.
6. Slide the fuel filter from the bracket.
7. Inspect the fuel pipe O-rings for cuts, nicks, swelling, or distortion. Replace the O-rings if necessary.

1. Slide the fuel filter into the bracket.
2. Remove the caps from the fuel pipes.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Connect the threaded fittings (1) to the fuel filter.

Tighten
Tighten the fittings to 25 N·m (18 lb ft).

4. Lower the vehicle.
5. Tighten the fuel fill cap.
6. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
7. Inspect for leaks using the following procedure:

7.1.	Turn the ignition ON, with the engine OFF for 2 seconds.

7.2.	Turn the ignition OFF for 10 seconds.

7.3.	Turn the ignition ON, with the engine OFF.

7.4.	Inspect for fuel leaks.
