Installation & Application Notes

Use clean, filtered fuel — fuel injection components have micron-level tolerances. Prime fuel system before cranking to avoid dry-start damage. Replace fuel filter whenever servicing injection components. Calibrate injectors after replacement if equipment has ECU.

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 priming pump include difficulty in starting the engine, especially after it has been sitting. If ignored, the engine may begin to stall intermittently during operation, particularly under load. Continued operation with a faulty pump can lead to inconsistent fuel delivery, potentially affecting engine performance and longevity.

Installation Tip

Ensure all fuel lines are properly seated and free of kinks before installing the new pump. Avoid overtightening the mounting bolts, which can damage the pump housing.

Service Note

Inspect fuel lines and fittings for any signs of damage or leaks when replacing the fuel priming pump.
