Fuel Line Coupler: Description and Operation

CAUTION: In Order To Reduce the Risk of Fire and Personal Injury: Always cover nylon fuel pipes with a wet towel before using a torch near them. Also, never expose the vehicle to temperatures higher then 115°C (239°F) for more than one hour, or more than 90°C (194°F) for any extended period. Take care not to nick or scratch the nylon fuel pipes. If damaged, they must be replaced.


Quick-connect type fittings provide a simplified means of installing and connecting fuel system components. Depending on the vehicle model, there are two types of quick-connect fittings, each 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. O-rings, located inside the female connector, provide the fuel seal. Integral locking tabs or fingers hold the quick-connect fittings together.
