Descriptive
WARNINGS: 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 9O° (i94° 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).
CAUTIONS:
-
Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and
passages.
-
Always maintain cleanliness when servicing fuel system components.
