The fuel tank (5) stores the fuel supply. A mechanical fuel injection pump (10), located below the engine intake, draws fuel through the fuel injector control module (6) and the fuel filter (7). The fuel is used as a coolant for the fuel injector control module. The fuel pump output is controlled by the ECM, and provides fuel at the pressure needed by the fuel injectors (3). The fuel injectors supply fuel directly to the combustion chambers of the engine. A separate pipe returns unused fuel through a fuel cooler (4) and to the fuel tank.
