Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Injection Pump
The Diesel Kiki single plunger mechanical injection pump contains a low pressure vane-type fuel pump, a high pressure distributor-type injection pump, a centrifugal governor, and an injection timing advance mechanism.
The vane pump output pressure (sometimes referred to as injection pump body pressure) averages between 50 to 100 psi depending upon engine speed and application. The plunger injection pump boosts the fuel pressure to about 2000 psi. The pump assembly is also equipped with an electric fuel shut-off valve and a cold start device for fast idle speed actuation.
