Fuel Hose/Pipes Replacement - Chassis Engine to Fuel Filter

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 Fuel Pressure Relief .
3. Disconnect the fuel feed and return pipes (3) from the engine compartment fuel pipes (4).
4. Remove the fuel pipes from the bellhousing stud retainer clip (2).



5. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
6. Disconnect the fuel feed pipe (5) at the fuel filter.



7. Disconnect the chassis fuel return pipe (4) at the rear fuel return pipe (3).



8. Remove the fuel pipe retaining clips (1). Note the location of the retaining clips for installation.
9. Remove the fuel feed and return pipes (2).

1. Position the fuel feed and return pipes (2) in the vehicle.

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.

2. Install the fuel pipe retaining clips (1).

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




3. Connect the chassis fuel return pipe (4) to the rear fuel return pipe (3).



4. Connect the fuel feed pipe (5) to the fuel filter.
5. Lower the vehicle.



6. Connect the fuel feed and return pipes (3) to the engine compartment fuel pipes (4).

Ensure the O-rings are in place

Tighten
Tighten the fuel pipe fittings to 27 N·m (20 lb ft) using a backup wrench.

7. Install the fuel pipes to the retainer clip (2).

Tighten
Tighten the fuel pipe retainer clip nut to 28 N·m (21 lb ft).

8. Tighten the fuel filler cap.
9. Connect the negative battery cable.
