Important: Clean the fuel filter connections and surrounding area before disconnecting the fuel lines in order to avoid possible fuel system contamination.

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 the fuel filter connections.
4. Using a flare nut wrench and backup wrench, disconnect the fuel lines (1) from the fuel filter.
5. Cap the fuel lines in order to prevent possible fuel system contamination.
6. Remove the fuel lines from the retainers.
7. Remove the fuel filter bracket nuts.
8. Pull out the filter/bracket in order to separate the lines from the filter.
9. Slide the fuel filter from the bracket.
10. Inspect the fuel line O-rings for cuts, nicks, swelling, or distortion. Replace the O-rings if necessary.
11. If a restricted fuel filter is found, clean the entire fuel system. Refer to Fuel System Cleaning .

1. Slide the NEW fuel filter into the bracket.
2. Remove the caps from the fuel lines.
3. Pull out the filter/bracket in order to insert the lines into the filter.
4. Tighten the fittings until snug.

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.

5. Install the fuel filter bracket nuts.

Tighten
Tighten the nuts to 12 N·m (106 lb in).

6. Install the fuel lines to the retainers.
7. Using a flare nut wrench and backup wrench, tighten the fuel lines (1).

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

8. Lower the vehicle.
9. Install the fuel fill cap.
10. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
