The VRO2 is on the motor slippery sent me a very informative link http://continuouswave.com/whaler/reference/VRO.html where I saw how to identify between the two it does have a four wire setup also there is a small filter aswell near the pump also a small white plastic coupling right before the VRO pump itself not sure what for Capt Bob when the tank was empty I didn't notice a pump in the tank not to say I was looking for one but if it is in the tank would it be near the fill spout? If I can found out how to upload pics on here I'll take some either tonight or tomorrow after work. There is also what looks like an electrical line that runs out of the oil tank aswell? and no matter if it is the oil or not the fuel lines most certainly need replacing once again guys thanks for your input like always you all have been most helpful
