Removal Procedure
Tools Required:
J 37088-A tool set, Fuel Pipe Quick-Connect Separator
Caution: In order to Reduce the Risk of Fire and Personal Injury:
• If nylon fuel pipes are nicked, scratched or damaged during installation,
Do Not attempt to repair the sections of the nylon fuel pipes. Replace them. • When installing new fuel pipes, Do Not hammer directly on the
fuel harness body clips as it may damage the nylon pipes resulting in a possible
fuel leak. • Always cover nylon vapor pipes with a wet towel before using a
torch near them. Also, never expose the vehicle to temperatures higher than
115°C (239°F) for more than one hour, or more than 90°C (194°F)
for any extended period. • Before connecting fuel pipe fittings, always apply a few drops
of clean engine oil to the male pipe ends. This will ensure proper reconnection
and prevent a possible fuel leak. (During normal operation, the O-rings located
in the female connector will swell and may prevent proper reconnection if
not lubricated.)
Notice: Do not attempt to straighten any kinked nylon fuel lines. Replace any kinked nylon fuel feed or return pipes in order to prevent damage to the vehicle.
- Relieve the fuel system fuel pressure. Refer to Fuel Pressure Relief .
- Clean all engine fuel pipe connections and areas surrounding the engine fuel pipe connections before disconnecting the engine fuel pipe connections to avoid possible contamination of the fuel system.
- Disconnect the quick-connect fittings in the engine compartment. Refer to Metal Collar Quick Connect Fitting Service .
- Raise the vehicle.
- Disconnect the quick-connect fitting at the front frame rail. Refer to Metal Collar Quick Connect Fitting Service .
- Cap the fuel feed pipe and the fuel return pipe as needed to stop any fuel leakage.
- Remove the fuel feed and fuel return pipe attaching hardware and the fuel feed and fuel return pipes.
- Note the position of the fuel feed and return pipes and the fuel feed and return pipe attaching hardware for installation.
- Inspect the pipes for bends, kinks and cracks.
- Replace the fuel pipes if necessary.
Important: Clean all engine fuel pipe connections and areas surrounding the engine fuel pipe connections before disconnecting the engine fuel pipe connections to avoid possible contamination of the fuel system.
Installation Procedure
Caution: In order to Reduce the Risk of Fire and Personal Injury: If nylon fuel pipes are nicked, scratched or damaged during installation, they must be replaced.
- Install the new fuel feed and return pipes and the fuel pipe attaching hardware as noted during removal.
- Remove the caps from the fuel feed pipe and the fuel return pipe.
- Install new plastic connector retainers on the fuel pipes.
- Connect the quick-connect fitting at the front frame rail. Metal Collar Quick Connect Fitting Service .
- Lower the vehicle.
- Connect the quick-connect fittings in the engine compartment Refer to Metal Collar Quick Connect Fitting Service .
- Add fuel and Reinstall the fuel fill cap.
- Tighten the fuel tank filler pipe cap.
- Reconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
- Inspect for leaks:
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.
