Fuel Supply Line: Description and Operation
PURPOSEFuel is delivered under pressure through the supply fuel tube and fuel filter to the fuel injection supply manifold.
OPERATION
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 line. All fuel lines run parallel to each other underneath the LH side of the vehicle. Fuel pressure is controlled by a fuel pressure regulator mounted at the return side of the fuel injection supply manifold.
