INSTALLATION PROCEDURE
CAUTION: In order to reduce the risk of fire and personal injury observe the following items:
^ Replace all nylon fuel pipes that are nicked, scratched or damaged during installation, do not attempt to repair the sections of the nylon fuel pipes
^ Do not hammer directly on the fuel harness body clips when installing new fuel pipes. Damage to the nylon pipes may result in a 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.
^ Apply a few drops of clean engine oil to the male pipe ends before connecting fuel pipe fittings. 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. Remove the protective caps from the replacement lines.
IMPORTANT: Wherever the lines pass through the metal, be sure that the grommets, where used, are installed and in good condition.
2. Install the fuel lines through the fender well from the engine compartment.
