Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is cool. Work in a well-ventilated area.
2. Relieve Fuel Pressure: Loosen the fuel cap to vent the tank.
3. Disconnect Lines: Carefully label and disconnect the fuel inlet, outlet, and vacuum pulse lines from the old pump. Have a rag ready to catch any residual fuel.
4. Remove Old Pump: Unbolt the two mounting screws holding the old fuel pump to the engine block.
5. Clean Surface: Remove the old gasket and thoroughly clean the mounting surface on the engine block to ensure a proper seal.
6. Install New Pump: Position the new gasket and fuel pump, then tighten the mounting screws evenly.
7. Reconnect Lines: Securely reattach the fuel and vacuum lines to their correct ports on the new pump. Use the included cable ties to secure them if needed.
8. Prime and Test: Reconnect the battery. Squeeze the primer bulb until firm. Start the engine and carefully inspect for any fuel leaks around the pump and its connections.

Troubleshooting & FAQ

How do I confirm this fits my engine?
First, check the Compatible Engine Models table on this page. Verify your engine's horsepower, and year range matches the listings. Next, use our Johnson/Evinrude Serial Number Guide to confirm your model. Finally, compare your original part number to the ones in our Part Number Cross-Reference table.

What are the signs of a failing fuel pump?
Common symptoms include difficulty starting, engine sputtering or stalling at low speeds, loss of power at high speeds, and inconsistent performance. A visible fuel leak from the pump body is also a clear sign of failure.

I see some aftermarket pumps have a different camshaft pulse hole. Will this one work?
Yes, this pump is designed to match the OEM specification for vacuum-operated fuel delivery on the listed models. It is a three-port design that relies on crankcase pressure pulses for operation. Always ensure the mounting surface is clean and the gasket seals properly for correct function.
