Replace my VRO fuel/oil pump with standard (2000 OMC 40hp)

#1 Post by guy48065 » Mon Jun 10, 2019 7:09 am

The more time I spend under the hood on my Johnson 40 the less I like the vacuum-driven oil/fuel pump. I've seen discussions of replacing this pump with a standard one, and I've now heard the same thing from 2 different outboard mechanics ("it's not a question of IF it will fail, but WHEN").

I can probably feel my way thru the project, but how do I find the right pump for my motor that came with a different one? There are mounting bosses & a manifold vac port right next to the fuel filter. Will ANY non-VRO pump from a similar year 40-ish hp Johnson work?

"I thought" I read about this conversation in this forum. Maybe not.

I am in the same situation my fuel pump went out and I started looking for just the pump and not the vro them I realized the PO of my boat had blocked off the vro and was using pre mix. I was able to find a fuel pump that a replacement for the vro type pump grrr 310 bucks. Or u can get a bracket and use a replacement fuel,pump for non vro stuff bout 15.00

My motor already has the mounting bosses for the traditional pump, which costs about 1/4 what a VRO pump costs.

But it's not the cost. It's the idea that the oil is added IN the pump and if anything goes wrong and oil stops, you get a warning tone as your motor is is seizing.

I like the convenience of filling the tank with regular gas, but I don't like the BIG downside.
