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 transfer pump include intermittent engine hesitation or a slight loss of power. If ignored, the engine may begin to stall frequently or refuse to start, especially when warm. Continued operation with a compromised pump risks uneven fuel delivery, leading to poor combustion and potential engine damage.

Installation Tip

Ensure the fuel tank is clean before installation to prevent debris from entering the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing and cause leaks.

Service Note

Always replace the fuel filter(s) when servicing or replacing the fuel transfer pump.
