To Ruppstang yellow wire

The gas gauge shows full when yellow wire was grounded. So I am assuming I have to take sending unit back out.

Yes your problem is in the back but before you take it back out I would ground the sending unit with the wire hooked up. Then check and see if it is reading, If so you need to ground the tank.

One way to save the pain of finding out you have a bad sender is before installing it in the tank ground it's frame and hook up the sender wire. Then move the float arm up and down while checking the reading on the gage.

The circuit is looking for a Ground through the sending unit.

Either the tank is not Grounded to the frame of the car, or the sending unit is not Grounded to the tank.
BOTH MUST BE GROUNDED.
