Installation & Application Notes

Never run an engine without a filter — even briefly causes abrasive damage. Pre-fill fuel filters with clean fuel before fitting to reduce prime time. Replace O-rings on filter housings every second service. Record change dates on filter housing.

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 transfer pump include a noticeable loss of engine power, especially when under load, and rough idling. If the pump's performance degrades further, the engine may stall unexpectedly or refuse to start due to insufficient fuel supply. Continued operation risks severe engine damage from fuel starvation.

Installation Tip

Ensure all fuel lines are properly connected and free of kinks before installing the new pump to prevent fuel leaks or restrictions. Do not reuse old seals or gaskets; always use new ones provided with the assembly.

Service Note

Inspect the fuel filters and water separator for excessive contamination, as this can indicate issues with fuel quality or the fuel tank.
