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 failing fuel injection pump include a noticeable reduction in engine power and increased fuel consumption. If left unaddressed, the engine may begin to run rough, hesitate under load, and produce excessive black smoke. Continued operation with a faulty pump can lead to uneven cylinder firing and potential engine damage.

Installation Tip

Ensure the fuel system is thoroughly flushed to remove any debris before installing the new pump. Avoid overtightening fuel line connections, as this can damage the fittings and cause leaks.

Service Note

Always replace the fuel filter(s) when servicing the fuel injection pump to prevent contamination of the new component.
