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

Early indicators of a failing fuel injection pump include engine misfires, a noticeable decrease in power, or black smoke from the exhaust. If left unaddressed, the pump's performance will degrade further, leading to rough idling, increased fuel consumption, and potential stalling. Continued operation with a faulty pump can result in uneven cylinder firing and damage to the fuel system components.

Installation Tip

Ensure the fuel system is thoroughly purged of air after installing the new pump to prevent starting issues. Do not overtighten the fuel line fittings, as this can strip the threads.

Service Note

Always replace the primary and secondary fuel filters when installing a new fuel injection pump to ensure system cleanliness.
