Troubleshooting & FAQ
What does this kit replace?
This kit is designed to replace pre-1984 VRO (Variable Ratio Oiling) pumps on compatible Johnson/Evinrude motors. It effectively converts the engine from an auto-oiling system to a simpler, reliable pre-mix fuel system.
Do I still need to use the VRO oil tank after installation?
No. This kit bypasses the entire VRO system. You must pre-mix your gasoline and 2-stroke oil at a 50:1 ratio (1 pint of oil to 6 gallons of gas) in your main fuel tank.
How do I know if my old fuel pump is failing?
Common symptoms of a failing fuel pump include the engine bogging down at high RPMs, difficulty starting, engine stuttering or surging, or visible fuel leaks from the pump housing itself.
Is this a direct bolt-on replacement?
Yes, for the specified engine models, this is a bolt-on replacement. The included custom bracket is designed to mount on the silencer cover. Always compare the new pump to your old one before installation to confirm fitment.
