Hey guys, I bought a 1987 johnson 140. I was not there to make the purchase, but was started and running before purchase was made. Anyway I got everything worked out except the VRO. I'm not sure if it's disconnecteded or not. I'm thinking it is already disconnected. I can't find any electrical wire running to it. I tried to upload a picture but it kept saying it failed.

Looking at the VRO from the side. There is a inlet without a hose conneted on the left that is what I'm thinking is oil intake, on the right side is what Im thinking is an outlet to the carbs, and what's on top is what I'm thinking is the pulse port. Problem is this doesn't seem to match anything I have come across for details and diagrams.
 
Justin... Any VRO that I have knowledge of has:

One (1) fitting on top that leads to the carburetors.

Three fittings on the bottom as follows:

One (1) large hose at the front or rear, depending on how you're looking at it, leading to the power-head. This is the pressure/vacuum line.

One (1) large (possibly slightly smaller) hose located in the center. This is the incoming fuel (gasoline) hose.

One (1) smaller diameter hose at the other end... the fitting is obviously smaller also. This is the incoming oil supply hose.

The proper method to change back to the fuel/oil premix setup is as follows. You can use this to compare with what you have to determine your present setup.

(VRO Pump Conversion To Straight Fuel Pump)
(J. Reeves)

You can convert the VRO pump into a straight fuel pump, eliminating the oil tank and VRO pump warning system, but retain the overheat warning setup (and fuel restriction warning if so equipped) by doing the following:

1 - Cut and plug the oil line at the engine so that the oil side of the VRO pump will not draw air into its system. Trace the wires from the back of the VRO to its rubber plug (electrical plug) and disconnect it.

2 - Trace the two wires from the oil tank to the engine, disconnect those two wires, then remove them and the oil tank.

3 - Mix the 50/1 oil in the proper amount with whatever quantity fuel you have. Disconnect the fuel line at the engine. Pump the fuel primer bulb until fuel exits that hose with the tint of whatever oil you used. Reconnect the fuel hose.

That's it. If you want to test the heat warning system to ease your mind, have the key in the on position, then ground out the tan heat sensor wire that you'll find protruding from the cylinder head. The warning horn should sound off.
