Tool Required

J 34730-1A Fuel Pressure Gauge

Important: 

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.
2. Relieve the fuel system pressure. Refer to the Fuel Pressure Relief .
3. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
4. Lower the left muffler (auto trans equipped vehicles only). Refer to Muffler Replacement in Engine Exhaust.
5. Clean all the fuel filter/pressure regulator connections and the surrounding areas before disconnecting the fuel pipes in order to avoid possible contamination of the fuel system.
6. Disconnect the fuel feed pipe quick-connect fitting (1) from the fuel filter/pressure regulator (2). Refer to Plastic Collar Quick Connect Fitting Service .
7. Disconnect the fuel return pipe quick-connect fitting (4) from the fuel filter/pressure regulator (2). Refer to Plastic Collar Quick Connect Fitting Service .



8. Remove the fuel filter/pressure regulator bracket mount nut (2).
9. Disconnect the fuel system ground strap from the fuel filter/pressure regulator mounting stud.



10. Disconnect the fuel feed pipe (3) from the outlet side of the fuel filter/pressure regulator (2).



11. Remove the fuel filter/pressure regulator and bracket (1) from the stud (3).
12. Cap the fuel pipes in order to prevent possible fuel system contamination.
13. Remove the fuel filter/pressure regulator from the bracket.

1. Remove the protective caps from the new fuel filter/pressure regulator.
2. Install the new plastic quick connector retainers on the fuel filter/pressure regulator inlet and outlet tubes. Install the new retainers in the same positions as on the old fuel filter/pressure regulator.
3. Install the fuel filter/pressure regulator into the bracket.
4. Remove the caps from the fuel pipes.
5. Connect the fuel feed pipe (3) to the outlet side of the fuel filter/pressure regulator (2).



6. Install the fuel filter/pressure regulator and the bracket (1) to the mounting stud (3).



7. Engage the anti-rotation tab (3) of the fuel filter/pressure regulator bracket (2) into the hole of the tunnel reinforcement (1).



8. Connect the fuel system ground strap to the fuel filter/pressure regulator mounting stud.

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.

9. Install the fuel filter/pressure regulator bracket nut (2).

Tighten
Tighten the fuel filter/pressure regulator bracket nut to 4.5 N·m (40 lb in).




10. Connect the fuel return quick-connect fitting (4) to the fuel filter/pressure regulator (2). Refer to Plastic Collar Quick Connect Fitting Service .
11. Connect the fuel feed quick-connect fitting (1) to the fuel filter/pressure regulator (2). Refer to Plastic Collar Quick Connect Fitting Service .
12. Raise the left muffler (auto trans equipped vehicles only). Refer to Muffler Replacement in Engine Exhaust.
13. Lower the vehicle.
14. Tighten the fuel filler cap.
15. Connect the negative battery cable.
