Fuel Return Line: Description and Operation

PURPOSE
Routes unused fuel back to fuel tank.

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.
