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 sign of a failing fuel transfer pump is often a noticeable decrease in engine power, especially under load. If ignored, the engine may begin to stall intermittently or run rough, making operation difficult. Continued use with a weak pump can lead to fuel starvation and potential engine damage.

Installation Tip

Ensure the fuel tank is clean and free of debris before installation to prevent contamination of the new pump. Do not overtighten the mounting bolts, as this can damage the pump housing.

Service Note

Always replace the fuel filter when replacing the fuel transfer pump to ensure clean fuel delivery.
