Troubleshooting & FAQ
How do I know if my fuel pump is failing?
Common symptoms of a failing fuel pump include the engine bogging down under acceleration, surging, difficulty starting, excessive fuel consumption, or stalling at low speeds. A visual inspection may also reveal cracks or fuel leaks on the pump body.
Will this pump fit my specific engine model?
This pump is designed for the Johnson/Evinrude HP and year ranges specified in the compatibility table. To guarantee fitment, the most reliable method is to verify that your original part number is 438555, 0438555, 433386, or 0433386.
What is the function of the third port?
This is a vacuum-operated fuel pump. The third port connects to the engine crankcase via a hose. The natural pressure pulses from the crankcase act on a diaphragm inside the pump, driving the fuel from the tank to the carburetors.
Is the mounting gasket included?
Yes, a new mounting gasket (replaces OEM 0303615) is included in the package to ensure a proper, leak-free seal against the engine block.
What are the OEM vs. Aftermarket parts?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
