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 initial sign of a failing high-pressure oil pump is often a noticeable reduction in engine power or rough engine operation. If the pump continues to degrade, it can lead to intermittent stalling, difficulty starting, or complete loss of fuel system pressure. Continued operation with a faulty pump risks severe damage to the fuel injection system and engine components.

Installation Tip

Ensure all fuel lines and fittings are clean and free of debris before connecting them to the new pump. Always prime the fuel system according to the manufacturer's procedure after installation to remove air.

Service Note

Inspect the fuel injectors, fuel lines, and fuel filter for any signs of contamination or wear.
