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

Initial symptoms of a failing high-pressure fuel pump include intermittent engine sputtering or a noticeable loss of power, especially under load. This can progress to difficulty starting the engine or a consistently rough idle. If left unaddressed, the pump can fail completely, resulting in an immediate engine shutdown.

Installation Tip

Ensure the fuel system is thoroughly purged of air and any contaminants before connecting the new pump. Always use new sealing washers and tighten fittings to the specified torque to prevent fuel leaks.

Service Note

Replace the primary and secondary fuel filters, and inspect the fuel tank for sediment when servicing the high-pressure fuel pump.
