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 pump include intermittent engine sputtering or a rough idle. If the problem persists, the engine may become difficult to start, especially when warm, and experience significant power loss under load. A completely failed fuel pump will prevent the engine from running altogether, leading to unexpected downtime.

Installation Tip

Always bleed the fuel system thoroughly after installing a new fuel pump to remove any air. Ensure all fuel line connections are securely tightened to prevent leaks.

Service Note

Replace the primary and secondary fuel filters whenever the fuel pump is replaced to ensure clean fuel delivery.
