Troubleshooting & FAQ

Q: How can I confirm this fuel pump fits my specific Suzuki engine model?

A: The best way is to match your existing part number to the cross-reference list (e.g., 15100-90J11, 15100-90J1V). Additionally, check your engine's model, horsepower, and year against our compatibility table. This pump is a long shaft version, so verify its dimensions against your old part.

Q: What are the signs of a failing low-pressure fuel pump?

A: Common symptoms include difficulty starting, engine sputtering or stalling (especially at low speeds), rough idling, and loss of power. The engine may run fine at high RPMs but struggle at idle if the pump is weak.

Q: Is there any regular maintenance required for this fuel pump?

A: The pump itself is a sealed unit, but maintaining a clean fuel system is key. Regularly replace your boat’s fuel filters to prevent debris from damaging the pump’s internal components. Failure to do so is a common cause of premature pump failure.
