This is a fuel transfer pump group, responsible for moving fuel from the tank to the injection pump or primary filter.

Symptoms of a failing fuel transfer pump include engine sputtering, difficulty starting, loss of power, or stalling, especially under load.

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 may include intermittent hesitation or a slight loss of power when the engine is under load. If the pump's performance degrades further, it can lead to rough idling, difficulty starting, and eventual engine stalling due to insufficient fuel supply. This can prevent the equipment from completing its intended work.

Installation Tip

Before installing, prime the new pump with clean fuel to ensure lubrication and prevent dry running. Ensure all fuel line connections are tight and leak-free after installation.

Service Note

Always replace the primary and secondary fuel filters when servicing or replacing the fuel transfer pump group.
