(a) High pressure fuel flow
(b) Low pressure fuel flow
1. Fuel from the fuel tank is passed through a water separator and fuel filter by an electromagnetic fuel feed pump
and is supplied to the supply pump.
2.
Fuel is pressurized by the supply pump and fed to the rail and injectors.
3. The injectors inject fuel based on instructions from the engine ECU.
4. After injection, surplus fuel passes through overflow pipe and fuel cooler and is returned to the fuel tank.
