VRO pump replacement with standard fuel pump (a How To)

[Stinky_Hooker]

This is how to remove the old VRO oil injection and replace with a standard old school Johnson fuel pump. The VRO system on my boat has long since been disconnected and I premix fuel which IMO (EVERY VRO motor not under warranty should be but thats another issue).However even without use of the VRO oil injection feature its still acts as the fuel pump. It developed a fuel leak so rather than rebuild or replace the expensive (non needed) VRO I replaced with a standard fuel pump. you will need the 3 outlet pump for this. It has a the standard fuel in and fuel out connections as well as a third for the crank case vacuum line to hook too. I ordered a used but almost new unit off fleabay for about $50 as oposed to several hundred for a VRO replacement.


Old VRO pump still on motor



Comparison in size between the old and replacement. The weight reduction should add ~~30mph alone.







Hooked to crank case vacuum line:




If its not obvious the gas "IN" from the fuel tank goes on the outer black connection and the brass one in the middle goes to carbs.

Hooked up and running.




I also took the stainless VRO mounting bracket and made a new mount for the new pump to be secured to but forgot to get a pic.



Hopefully this will help someone.
