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

Early indicators of a failing fuel transfer pump include intermittent engine stalling or rough idling. If the issue persists, the engine may experience a significant loss of power, especially under load, and starting difficulties. Continued operation with a faulty pump can lead to fuel starvation and potential damage to the injection system.

Installation Tip

Prime the new fuel pump assembly with clean fuel before installation to ensure immediate lubrication and prevent dry running. Avoid cross-threading the fuel line fittings, as this can cause leaks and necessitate replacement of the fittings.

Service Note

Replace the primary fuel filter and inspect the secondary fuel filter when installing a new fuel transfer pump.
