The fuel pump consists of a transfer pump and a high-pressure fuel delivery pump. The
transfer pump draws fuel from the fuel tank through the fuel filter and delivers the fuel to

The fuel metering valve controls the quantity of fuel that is allowed to enter the high-
pressure fuel pump chambers. Excess fuel volume developed in the high-pressure fuel
pump chamber is returned to the fuel tank. The fuel metering valve is controlled by the
