Installation Guide
- Ensure the engine is off and cool, and disconnect the battery terminals.
- Carefully relieve any pressure in the fuel system according to the manufacturer's guidelines.
- Place a rag under the fuel pump to catch any spilled fuel. Note the orientation of the fuel lines and disconnect them.
- Unbolt and remove the old fuel pump from the engine block.
- Clean the mounting surface on the engine, ensuring it is free of old gasket material or debris.
- Position the new fuel pump and gasket, and securely tighten the mounting bolts.
- Reconnect the fuel lines to the correct inlet and outlet ports on the new pump.
-
Crucial: This pump requires premixed fuel. Verify the engine's oil injection system is properly bypassed and you are using a 50:1 fuel/oil mixture.
- Reconnect the battery.
- Prime the fuel system by squeezing the primer bulb until firm. Check all connections for leaks.
- Start the engine and let it run, checking again for any signs of fuel leaks before taking your boat on the water.
Troubleshooting & FAQ
Q: How can I be sure this fuel pump will fit my outboard?
A: This pump is specifically for Johnson and Evinrude 60-degree V4 and V6 engines (90-175 HP) made between 1991 and 2006. It's a direct replacement for OEM part numbers 438400 and 5004558. The best way to confirm is to compare your original part to the product images and check the part number.
Q: Does this pump automatically mix oil with the fuel like the original VRO?
A: No, this is a critical point. This is a "fuel-only" pump designed for systems where the VRO's oiling function has been disabled. You must use fuel that is premixed with oil at a 50:1 ratio. It will not mix oil for you.
Q: What are the symptoms of a failing fuel pump?
A: Common signs include difficulty starting the engine, stalling, sputtering or hesitation during acceleration, loss of top-end power, and engine surging. If your motor bogs down under load, a weak fuel pump is a likely culprit.
