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 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° 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.)

- Do not attempt to straighten the kinked nylon fuel lines. Replace any kinked nylon fuel feed or return pipes.
