Fuel Injection Pump

The injection pump is located on the engine lower right side and driven by a toothed belt. The pump draws fuel from the tank, pressurizes it and sends a specific quantity to each cylinder at the proper time. Excess fuel is returned from the injectors and sent back to the tank.

A fast idle system is used when coolant is below a specified temperature. A vacuum unit actuates the throttle and increases idle speed. A fuel cut solenoid is actuated by the ignition switch and stops fuel flow at the pump so the engine can be shut down. The injection pump is also equipped with an altitude compensator for proper fuel delivery at high altitudes.
