Troubleshooting & FAQ

How do I know if my fuel pump needs replacement?

Common signs include hard starting, engine stalling under load, inconsistent idle, or visible fuel leaks near the pump assembly. Low fuel pressure readings also indicate pump failure.

Is this pump compatible with ethanol fuel?

Yes, this fuel pump is designed to handle modern marine fuel formulations including ethanol-blended gasoline up to E10.

Can I install this myself or do I need a mechanic?

Installation is straightforward for those with basic mechanical skills and tools. However, working with fuel systems requires care—professional installation is recommended if you're unfamiliar with marine engine service.

Will this fit my Yamaha 25HP 2-stroke?

No, this pump is designed exclusively for Yamaha 25HP 4-stroke engines from 2006 onward. Always verify your engine's stroke type and year before ordering.
