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 difficulty starting the engine, especially when cold, and a reduction in overall engine power. If ignored, the engine may begin to run rough, misfire, and produce excessive black smoke. Continued operation risks severe engine damage due to improper fuel delivery and combustion.

Installation Tip

Ensure the fuel system is thoroughly bled of air after installation to prevent starting issues. Avoid introducing any contaminants into the fuel system during the replacement process.

Service Note

Always replace the fuel filters when servicing or replacing the fuel injection pump to prevent contamination of the new component.
