Note the routing of fuel lines and electrical connectors, then disconnect them from the old pump.
Unbolt and remove the old fuel pump assembly.
Mount the new pump in the same orientation, ensuring it is secure.
Reconnect fuel lines and electrical harness, ensuring all fittings are tight.
Reconnect the battery.
Prime the fuel system as required by your engine manual.
Start the engine and carefully inspect for any leaks around the pump and fittings before operation.

Troubleshooting & FAQ

How do I know if my fuel pump is failing?

Common signs of a failing fuel pump include engine sputtering, hesitation or stalling under load, loss of power, difficulty starting, or an unusual whining sound coming from the pump's location.

What engines does this pump fit?

This aftermarket pump is a direct replacement for Mercruiser applications using part number 892267A51 and Parsun F40 4-stroke outboards. Always verify your original part number before ordering to ensure compatibility.
