Fuel Return Line: Description and Operation
PURPOSE
Routes fuel between tank and injectors.
OPERATION
Fuel is supplied to the engine, and returned to the tank through steel fuel line running along the bottom of the vehicle. Where connections are
made, high pressure fuel hose and steel clamps are used due to high fuel system pressure.
WARNING: Do not use standard rubber fuel line or worm type clamps, due to a risk of leakage or fire. Use only fuel line and clamps
designed for fuel injection systems.
