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

An initial symptom of a failing 3941398 pump may be a slight hesitation or stumble during acceleration. If the issue progresses, the engine may experience rough idling, difficulty starting, or intermittent stalling as fuel delivery becomes inconsistent. Continued operation with a weak pump can lead to fuel starvation, potentially causing engine damage.

Installation Tip

Ensure all fuel lines are properly disconnected and capped to prevent fuel spillage and contamination during removal. When installing the new pump, ensure all seals are correctly seated and all connections are tightened securely to prevent leaks.

Service Note

Inspect the fuel tank for sediment and clean or replace the primary fuel filters when replacing the fuel transfer pump assembly.
