Fuel Supply Line: Service and Repair
REMOVAL PROCEDURECAUTION: 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.)
1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Disconnect the clamp and the fuel feed outlet hose from the fuel feed pipe near the fuel tank.
3. Disconnect the clamp and the fuel return hose from the fuel return pipe near the fuel tank.
4. Disconnect the clamp and the fuel vapor hose from the fuel vapor pipe near the fuel tank.
5. Lower the vehicle.
6. Disconnect the clamp and the fuel feed hose (2) from the fuel feed pipe in the engine compartment.
7. Disconnect the clamp and the fuel return hose (3) from the fuel return pipe in the engine compartment.
8. Disconnect the fuel vapor hose (1) from the fuel vapor pipe in the engine compartment.
9. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
10. Remove the 6 nuts (1) and the 3 sections of pipe guards (2) from the vehicle underbody.
11. Apply pressure (1) to the corners of the pipe clamps (2) in order to release the pipes.
12. Remove the fuel feed, the fuel return, and the fuel vapor pipes (2) from the pipe clamps (3). Leave the brake lines (1) secure.
INSTALLATION PROCEDURE
1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Install the fuel feed pipe, the fuel return pipe, and the fuel vapor pipe into the pipe clamps on the vehicle underbody.
