Fuel Line Coupler: Description and Operation

QUICK CONNECT FITTINGS
Quick connect type fittings provide a simplified means of installing and connecting fuel system components. Two types of quick disconnect fittings are used at various parts of the fuel system. O-rings, located inside the female socket provide the fuel seal. One type quick disconnect fitting uses hand releasable locking tabs. The other type of quick disconnect fitting has a locking tab that requires the use of a special tool.

FUEL LINE O-RINGS
The fuel line O-rings used are made of Viton. They are brown in color. Viton is less affected than rubber by the additives used in many fuels. Therefore, rubber should not be used.
