Johnson VRO 150 identification help needed

[tsubaki]

From what I remember that year had the ability to use the VRO or/either dual fuel pumps. I had one, it had the VRO removed and an electric pump added. We removed the electric pump and installed two siphon pumps and premixed the fuel afterwards.
Picture of the fittings to go to the dual pumps.

I went through my stuff and found I had an "84 and not an "85 so there might be some dependencies between the two years.

Now I'm just lost. I've been told to ditch the self mixing and just premix. For all I know it might of already been done. I'll post some motor pics when
I get the boat home and maybe y'all can tell me what I got going on.

The likely hood is there to be able to use a VRO pump for the fuel pump only and premix and disconnect sensors to be able to do so.
