Installation Procedure

Caution: To Reduce the Risk of Fire and Personal In jury:

^ If nylon fuel pipes are nicked, scratched or damaged during installation, they must be replaced.

^ 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.

^ 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.)
