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 fuel injection pump often include a rough or uneven engine idle and a noticeable loss of engine power. If ignored, fuel delivery issues can worsen, leading to increased exhaust emissions and potential stalling. The most critical consequence is engine damage due to improper fuel delivery or prolonged operation with a severely compromised system.

Installation Tip

Ensure the engine timing is correctly set before installing the new pump, as improper timing will lead to poor performance and potential engine damage. Never reuse old fuel lines or fittings, as they can introduce contaminants into the new pump.

Service Note

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