Lumina V6-3.1L VIN J (2000)
Fuel Line Coupler: Description and Operation
CAUTION: 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 90°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.)
Quick-connect type fittings provide a simplified means of disconnecting and connecting fuel system components. Depending on the vehicle type, there
are two types of quick-connect fittings. Each are used at different locations in the fuel system. Each type of quick-connect fitting consists of a unique
female connector and a compatible male fuel pipe end. An O-ring is located inside the female connector, witch provides the fuel seal. Integral locking
tabs or fingers hold the quick-connect fittings together.
