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 injection pump include difficulty starting the engine or a noticeable unevenness in engine idle. If ignored, the pump's performance will degrade further, leading to significant power loss, increased fuel consumption, and potentially stalling. Continued operation risks incomplete combustion and damage to the fuel system components.

Installation Tip

Ensure the fuel system is properly bled of air after installation to prevent starting issues. Avoid introducing any dirt or contaminants into the fuel lines or pump during the replacement process.

Service Note

Replace the fuel filters and inspect all fuel lines and seals for leaks when installing a new fuel injection pump.
