Frequently Asked Questions
Will this fit Johnson 115 or 125 HP engines?
Not on horsepower alone. Those ratings are not included in the verified guide; use the exact OEM number.
Is this a VRO oil/fuel pump?
No. It is a pulse-operated fuel pump for specified non-VRO applications.
Is it genuine BRP?
The store listing is treated as an aftermarket replacement unless the product packaging specifically states genuine BRP.
Can I identify fitment from appearance?
No. Similar-looking pumps can have different pulse fittings and port layouts.
Compare the original part number, engine model code and installation interface before purchase. Professional installation is recommended where fuel or ignition systems are involved.
