Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of a failing fuel injection pump include a noticeable reduction in engine power and possibly rougher idling. If ignored, the engine may become increasingly difficult to start, exhibit excessive black smoke, and eventually run erratically or stall.

Installation Tip

Ensure the engine's timing is correctly set before installing the new pump to avoid incorrect fuel delivery and potential engine damage. Never reuse old fuel lines or fittings; always use new ones to prevent leaks and contamination.

Service Note

Replace the fuel filters and inspect the fuel injectors for proper operation whenever installing a new fuel injection pump.
