Installation Notes
- Disconnect the negative terminal of the battery. Relieve any pressure from the fuel system in a well-ventilated area.
- Identify and disconnect the fuel inlet, fuel outlet, vacuum pulse, and oil inlet lines from the original VRO pump.
- Carefully unbolt and remove the old VRO pump assembly from the engine block.
- Mount the new fuel pump kit using the original or supplied mounting hardware, ensuring it is secure.
- Connect the fuel line from the tank to the pump's inlet and the fuel line to the carburetors to the pump's outlet.
- Crucially, cap or plug the unused oil line from the oil tank and ensure the engine's vacuum/pulse nipple is connected to the new pump's pulse fitting.
- This kits bypasses oil injection. You must now use fuel premixed with 2-stroke oil at a 50:1 ratio (1 pint of oil to 6 gallons of gasoline).
- Use the primer bulb to fill the pump and fuel lines. Check thoroughly for any leaks before starting the engine.
Troubleshooting & FAQ
How do I know if this pump fits my engine?
This kit is designed for Johnson/Evinrude 90-115 HP V4 60° Looper motors that use OEM part #5007420, 438400, or 5004558. Always verify your engine model and original part number before ordering.
What does "eliminates VRO" mean?
This pump replaces the original Variable Ratio Oiling (VRO) system. After installation, you must use premixed fuel and oil (50:1 ratio) in your fuel tank, as the engine will no longer receive oil automatically from a separate tank.
Are the outlet fittings plastic?
No, this unit features machined (non-plastic) outlet fittings for enhanced durability and a secure seal, which is a common failure point on lower-quality alternatives.
What are the signs my old VRO pump is failing?
Common signs include the engine failing to start, bogging down at high RPMs, fuel starvation, or visible fuel/oil leaks from the pump housing. An inconsistent or non-functional warning horn for the VRO system is also a critical indicator.
