Motorcycle Repair: 1986 FXSTC oil tank outlets, oil tank, fxstc

Question
Hi Mike, I'm working on a 1986 FXSTC and neeed to know which oil line goes to which nipple on the oil tank. It is a horseshoe style tank with two nipples on the right side pointing forward toward the pump. In the bottom right corner is a bigger diameter nipple that had a hose connected to it that just went to a solid rod welded to the frame. I assume that the bigger nipple is a drain but that seems like rather poor engineering to me. The other two smaller nipples appear to go to the top of the inside of the tank. Can  you help me out? Many thanks, Mike in WY

Answer
The bigger one is the drain that is going to the solid rod. Look inside the tank to see where the inside lines go. The lowest one is the feed to the oil pump. The highest one is the return and the other one is the return from the motor.
Good luck and happy riding
Mike
