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.)
1. Relieve the fuel system fuel pressure. Refer to the Fuel Pressure Release Procedure. See: Fuel Filter/Fuel Pressure Release
2. 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.
