new here with VRO conversion question

I've given up and got a 2-3.5psi electric fuel pump for my 70hp 2000 OB Johnson. All I did was take the VRO pump out, plugged the oil line, plugged the vacuum on the block. Drained the fuel, not knowing how much was in the tank, put 50:1 mix in the tank but now she won't start. The new fuel pump is working fine. Do I need to bypass or disconnect something electrical?
Thanks for the advice.

Re: new here with VRO conversion question

if you removed the vro then you already disconnected the harness..that will stop the warning horn for low oil. no other reason for it to not start as long as your carbs are clean, fuel lines connected properly with no clogs, good compression, good spark

The first thing you should do is get rid of that electric fuel pump. They're a fire hazard on an outboard. Go back to something that is pulse operated.

Re: new here with VRO conversion question

Agree that an "electric fuel pump" is a bad idea. ONLY if there is a way to kill the pump if the engine stalls with the key on is that a safe installation. Without that feature you risk explosion and fire and harm to yourself and passengers. It is not worth the risk. there is plenty of discussion regarding this. Use the "search" feature to find the threads.

(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.
