Anyone have any good advise on removing my 1992 Evinrude 90hp VRO2 pump. I plan on mixing oil with gas manualy. <br /><br />Thanks,

Re: VRO Removal

Peters... The following may be of some use to you.<br /><br />(VRO Pump Conversion To Straight Fuel Pump)<br /><br />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 by doing the following:<br /><br />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.<br /><br />2 - Trace the two wires from the oil tank to the engine, disconnect those two wires, then remove them and the oil tank.<br /><br />3 - Mix the 50/1 oil in the proper amount with whatever quanity 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.<br /><br />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.

Thanks Joe, <br /><br />Will this setup pump the same amount of fuel as usual. I have no problem with mixing oil to fuel, it is better than spending 10 minutes blowing smoke at startup.

Re: VRO Removal

peters,<br /><br />Not to jump in the middle but Yes, it will pump the same. You will have no problems, as you are only getting rid of the "Oil" side of the pump.
