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

The first indication of a failing fuel transfer pump is often intermittent engine stalling or difficulty maintaining idle speed. As the pump weakens, the engine may experience significant power loss and rough running, particularly during acceleration or heavy load conditions. Continued use with a faulty pump can lead to fuel starvation and potential damage to the injection pump.

Installation Tip

Before installing the new pump, ensure the fuel lines are clean and free from any blockages or debris that could impede fuel flow. Avoid overtightening the mounting bolts, as this can distort the pump housing and cause leaks.

Service Note

Inspect the fuel filter and fuel lines for any signs of clogging or damage when replacing the fuel transfer pump.
