Fuel Line Coupler: Description and Operation
Quick-Connect Fittings
QUICK-CONNECT FITTINGS
Quick-connect type fittings provide a simplified means of installing and connecting fuel system components. There are three types of
quick-connect fittings used at different locations in the fuel system. Each type consists of a unique female socket and a compatible male connector.
O-rings, located inside the female socket, provide the fuel seal. Integral locking tabs or fingers hold the fittings together.
FUEL PIPE O-RINGS
Fuel feed and return pipe threaded connections at the fuel rail and fuel filter are sealed with replaceable O-ring seals. These O-rings seals are made
of special material, and should only be serviced with the correct service part.
