Re: Help hooking up oil tank
The OMC Carb motors only have a single oil line, and a ventilated cap. Does the tank have a part number on it? I have heard rumor that the e-TECs have an oil return line. You might see if it looks like that oil tank.
Merc oil tanks are pressurized to force oil to the motor resevoir. They obviously have two connections, one for oil and one for pressure, and a sealed cap.
