5007421 Fuel VRO Pump for Evinrude Johnson 3-Cyl | JLM Marine

Fuel VRO Pump for Evinrude Johnson 3-Cyl | JLM Marine

This VRO replacement fuel pump is designed for Evinrude Johnson 3-cylinder outboard engines rated at 60HP and 70HP, converting VRO-equipped models to a premix fuel system. Engineered to replace expensive oil injection VRO pumps, this assembly allows operators to run on oil and gas premix, eliminating the VRO oiling function.

This aftermarket pump directly replaces OEM part numbers 5007420, 5007421, and 5007422, as well as OMC #4-7359 and EMP #1399-07359. Designed for 90-degree outboard motors, it fits all VRO-equipped 3-cylinder models requiring rebuild or repair.

• Non-oiling conversion: Must premix oil & gas in your fuel tank at 50:1 ratio (1 pint oil to 6 gallons gas)
• Direct OEM replacement: Fits Evinrude Johnson 3-cyl 60HP and 70HP VRO-equipped engines
• 90-degree configuration: Compatible with 90-degree outboard motor designs

Installation Guide

1. Disconnect the battery and ensure the engine is off and cool before beginning work.
2. Locate the existing VRO fuel pump on your Evinrude Johnson 3-cylinder outboard motor.
3. Disconnect all fuel lines and electrical connections from the old VRO pump. Label lines for correct reinstallation.
4. Remove the mounting bolts securing the old VRO pump to the engine block.
5. Install the new fuel pump in the same position, aligning mounting holes with the engine block.
6. Secure the pump with the original mounting bolts, torquing to manufacturer specifications.
7. Reconnect fuel lines to the appropriate inlet and outlet ports on the new pump.
8. Since this is a non-oiling pump, disconnect and cap or remove the oil injection lines (they are no longer needed).
9. Prime the fuel system by squeezing the primer bulb until firm to remove air from the lines.
10. Prepare premixed fuel at a 50:1 ratio (1 pint of 2-stroke oil to 6 gallons of gasoline) and fill your fuel tank.
11. Reconnect the battery and start the engine, checking for fuel leaks around all connections.
12. Run the engine at idle for several minutes to ensure smooth operation and verify no leaks or abnormal sounds.

Troubleshooting & FAQ

Q: How do I confirm this fuel pump fits my engine?
A: This pump is designed for Evinrude Johnson 3-cylinder outboard engines rated at 60HP or 70HP that are VRO-equipped with a 90-degree motor configuration. Verify your engine's cylinder count, horsepower rating, and existing VRO system before ordering. Cross-reference your current pump's part number with 5007420, 5007421, or 5007422.

Q: What does "VRO conversion" mean and why must I premix fuel?
A: This pump eliminates the VRO (Variable Ratio Oiling) injection system, which automatically mixed oil into the fuel. With this conversion pump, you must manually premix 2-stroke oil and gasoline at a 50:1 ratio (1 pint oil per 6 gallons of gas) in your fuel tank before use.

Q: Will this pump work on V4 or V6 engines?
A: No, this specific pump is designed exclusively for 3-cylinder Evinrude Johnson outboards. It does not fit V4, V6, or 60° engine configurations. Check your engine's cylinder count and configuration before purchasing.

Q: How often should I replace this fuel pump?
A: Replace the fuel pump if you experience hard starting, loss of power, fuel starvation, or visible leaks. Regular inspection every season is recommended, and replacement intervals vary based on usage and fuel quality—typically every 3–5 years under normal conditions.

Q: What are common signs that my fuel pump is failing?
A: Symptoms include engine stalling or hesitation at high RPM, difficulty starting, poor acceleration, fuel leaks around the pump body, and inconsistent idle. If you notice any of these issues, inspect and test the fuel pump immediately.
