VROD4 – Fuel Pump VRO Delete Kit – Johnson/Evinrude

The VRO delete fuel pump kit lets you replace the original oil-injection VRO pump on many Johnson and Evinrude outboards with a simple diaphragm style fuel pump. Traditional VRO systems combine fuel and two-stroke oil in one pump, so they must meter both liquids to the engine. When the VRO unit leaks, fails, or becomes hard to source, many owners eliminate the oil injection altogether. They then install a dedicated fuel pump and use premixed fuel in the tank.

This replacement approach removes complex moving parts and simplifies the fuel delivery system. Most kits include a compact diaphragm pump, mounting bracket, hoses, and hardware that fit common VRO engines. These pumps deliver fuel reliably once you switch to premix, and many boat owners find them easier to maintain than the original VRO assembly.

With a VRO delete fuel pump installed, you no longer depend on the factory oil metering system. Instead, you mix your oil with gasoline before filling the tank. This method gives you full control over oil ratio and helps keep the fuel system simpler. Many people choose this solution because OEM VRO fuel/oil pumps can be expensive and prone to leaks as they age.

Overall, converting to a dedicated fuel pump and eliminating the VRO unit can improve reliability.
