Starting the engine activates the fuel pump (3), which draws fuel from the fuel tank (1) and routes it through the fuel filter
(2) to the vapor separator (4). The fuel is pressurized in the fuel-feed pump (FFP) (5); then passes through the high-
pressure filter (6) to the air rail (7), from there it is injected into the combustion chambers. The fuel regulator (8) regulates
fuel pressure so as to keep it 70 kPa (10 psi)higher than the pressurized air pressure (55OkPa Bopsi)to inject fuel into
combustion chamber after overcoming the air pressure mentioned in Air supply system as follows. Any excess fuelis
depressurized and diverted through the FFP case (9) and back to the vapor separator (4). The returned fuel contains air
bubbles left over from being pressurized at (5). These bleed from the top of the vapor separator (4) to the throttle body
(10) and is fed to the air intake system.
