Troubleshooting & FAQ
How do I confirm this pump is correct for my motor?
Compare the original pump with the product photos and compare your original part number with 0438562, 0434728, 18-7351, or JE-X04JO0002. Also verify the exact Johnson/Evinrude model, 9.9HP or 15HP rating, 2-stroke configuration, and applicable production year before ordering.
Will this pump work on a 4-stroke engine?
This listing is intended for the 2-stroke Johnson/Evinrude applications shown above. Do not install it on a 4-stroke engine unless the exact engine documentation confirms the same pump and part-number application.
What are common signs of a failing fuel pump?
Possible symptoms include hard starting, sputtering, stalling, loss of power, inconsistent fuel delivery, or fuel leakage around the pump. These symptoms can have other causes, so inspect the complete fuel system before replacing parts.
Is this an OEM pump?
No. This listing is for an aftermarket replacement corresponding to the part-number references shown in the matrix.
Is a gasket included with the pump?
The package contents list the fuel pump only. A gasket is not listed as included. Check the engine service information and prepare a suitable replacement gasket if required for your installation.
Can I install this myself?
Installation may be suitable for a person with marine-engine repair experience. Because fuel systems present a fire and environmental hazard, follow the engine service manual and use professional installation if you are unsure about the procedure.
How should I check the replacement before installation?
Compare the mounting pattern, fuel-line port arrangement, pump orientation, and original part number. Do not force a pump into place or operate the engine if the fit, connections, or sealing surface do not match.
Safety & Important Info
- Work in a well-ventilated area away from flames, sparks, and ignition sources.
- Relieve or contain fuel-system pressure as directed by the engine service manual.
- Verify the engine model, year, stroke, horsepower, and original part number before purchase.
- Inspect all fuel lines, clamps, fittings, and sealing surfaces during installation.
- Stop operation immediately if fuel leakage is present.
- This is an aftermarket replacement, not an OEM component.
