Product Details
This VRO Fuel Pump Rebuild Kit is designed as a replacement for Johnson/Evinrude outboard motors, covering 3-cylinder models from 60-70 HP and V4 Crossflow models made before 1984. It replaces the original VRO (Variable Ratio Oil) pump, requiring the use of pre-mixed fuel and oil.
This kit serves as a direct replacement solution for the pre-1984 Johnson/Evinrude VRO fuel pump system.
- Mounts directly to the engine bracket for straightforward installation.
- Requires pre-mixed fuel and oil at a 50:1 ratio, eliminating the original failure-prone VRO system.
- Includes an extended fuel hose for flexible routing.

- Connect the new hoses as indicated in the included mounting instructions.
- After installation, you must switch to a pre-mixed fuel and oil solution at a 50:1 ratio (1 pint of oil to 6 gallons of gasoline). Do not run the engine on gasoline alone.

Troubleshooting & FAQ
How do I know if my VRO pump is failing?
Common signs of a failing fuel pump include the engine refusing to start, bogging down at high speed, stalling unexpectedly, or sputtering. A physical inspection may also reveal cracks, fuel leaks, or a damaged housing on the old pump.
Why does this kit bypass the VRO system?
This kit converts the original Variable Ratio Oiling (VRO) system to a simpler, more reliable pre-mix setup. This eliminates a common point of failure, as a non-functioning VRO pump can lead to catastrophic engine damage from oil starvation. After installing, you must use a 50:1 fuel-to-oil mixture.
Is this kit difficult to install?
For individuals with baseline mechanical skills, installation is moderately easy and involves mounting the new pump and connecting hoses. However, because it is a critical fuel system component, professional installation is always recommended for safety and reliability.
Which specific engines does this kit fit?
This conversion kit is engineered for pre-1984 Johnson/Evinrude outboards, specifically 3-Cylinder models rated 60-70 HP and V4 Crossflow models that were originally equipped with the VRO pump system.
