REMOVAL PROCEDURE
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.)
NOTE: Refer to Cover and Plug Openings Note in Service Precautions.
IMPORTANT: Always maintain cleanliness when servicing fuel system components.
1. Remove the air cleaner intake duct.
2. Remove the brake master cylinder from the brake booster and reposition.
3. Relieve the fuel system fuel pressure. Refer to Fuel Pressure Relief Procedure.
4. Disconnect the fuel feed pipe quick-connect fitting (1).
5. Disconnect the evaporative emissions (EVAP) purge pipe quick-connect fitting (2).
