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 signs of a worn fuel pump gear may include intermittent engine misfires or a slight decrease in engine responsiveness. If left unaddressed, the gear's performance will degrade further, leading to significant power loss and potential stalling. Continued operation with a failing gear risks inconsistent fuel delivery, impacting overall engine health and operational efficiency.

Installation Tip

Ensure the fuel pump housing is thoroughly cleaned before installation to prevent contamination. Avoid overtightening the fuel pump assembly bolts, as this can distort the housing and damage the new gear.

Service Note

Inspect the fuel pump housing and drive shaft for wear or damage when replacing the fuel pump gear.
