Troubleshooting & FAQ
How do I know if this fuel pump fits my engine?
This pump is designed for specific Johnson and Evinrude horsepower ranges and years (18-35 HP, 1990–2000). Always verify the part numbers (438555 or 433386) and compare the photos to your original pump to guarantee a match before ordering.
What are the signs of a failing fuel pump?
Common symptoms include difficulty starting, engine sputtering or stalling at high speeds, loss of power, or visible fuel leaks from the pump housing. An engine that runs fine on a portable tank but not the main tank often points to a fuel delivery issue.
Is this a 2-line or 3-line fuel pump?
This is a 3-port (3-line) fuel pump. It has a fuel inlet, a fuel outlet to the carburetor, and a vacuum pulse port that connects to the engine crankcase to operate the pump's diaphragm.
What is the recommended replacement interval for an outboard fuel pump?
There is no fixed replacement interval. Fuel pumps are typically replaced when they fail. Proactive replacement every 5-7 years can prevent being stranded on the water, especially if your engine sits for long periods or is used in saltwater.
What is the difference between an OEM and an aftermarket part?
This listing is an aftermarket replacement (not OEM). It is built to OEM-level specifications with comparable materials and manufactured in an ISO 9002 facility, with batch-inspections for consistency.
