- Prime the fuel system if required, reconnect the battery, and inspect all connections for leaks before starting the engine.
Troubleshooting & FAQ
How can I confirm this pump fits my specific engine?
Confirm that your engine is a Johnson/Evinrude 9.9 HP or 15 HP outboard within the 1993–2006 application range, then match the original pump number to 434728 or 438562. Because applications can vary by exact model and configuration, also verify the engine model, year, serial-number range, mounting pattern, hose routing, and pump appearance before installation.
What are common signs of a failing fuel pump?
Symptoms may include hard starting, fuel starvation at higher speed, engine hesitation, sputtering, loss of power, or stalling. Check the fuel supply, filters, hoses, primer system, and pump connections before replacing the pump.
Is this for a 2-stroke or 4-stroke engine?
The documented application is for selected Johnson/Evinrude 9.9 HP and 15 HP outboards from 1993–2006. Do not determine fitment from horsepower or stroke type alone; match the original pump number and the complete engine model information.
Is the service kit included?
No. This listing is for one fuel pump assembly. The related service-kit reference is 18-7800 and should be purchased separately when required by the engine installation or service procedure.
What is the difference between this aftermarket pump and an OEM part?
This is an aftermarket replacement, not an original OEM component. It is intended to replace the listed manufacturer references when the engine application and physical configuration match.
Shipping speed & cost?
We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free; expedited options appear at checkout where available.
Warranty & returns?
Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details.

Safety & Important Info
- Work in a well-ventilated area away from flames, sparks, and ignition sources.

- Compare the replacement pump with the original part. Do not install it if the fittings, mounting points, or configuration differ.
- This is an aftermarket replacement, not an OEM component.
