quick-connect separator
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.) |
Notice: Do not attempt to straighten any kinked nylon fuel lines.
Replace any kinked nylon fuel feed or return pipes in order to prevent damage
to the vehicle.
