Fuel Return Line: Description and Operation







FUEL TUBES TRANSFER FUEL FROM THE FUEL TANK TO THE INTAKE MANIFOLD
Fuel is drawn from the fuel tank by a fuel tank mounted fuel pump. Fuel is then delivered under pressure through the supply fuel tube and fuel filter to the fuel injection supply manifold and then to the fuel injectors.

Excess fuel is returned to the fuel tank through the fuel return tube. A fuel evaporation pipe is routed from the fuel tank to the Evaporative Emission (EVAP) canister. All fuel tubes run parallel to each other underneath the RH side of the vehicle. Fuel pressure is controlled by a fuel pressure regulator mounted at the return side of the fuel injection supply manifold.
