I happened to have a sender unit out of the 69 midget and measured the resistance with it removed from the tank. It reads roughly from 20 to 250 ohms as the float goes from empty to full position. Now mine was not working correctly so I took it apart and discovered a weak point. Inside the case the arm of the float unit connects to the wiper blade that moves across the wirewound resistance surface. To assure good contact of the arm to the case/chassis there is a spring that presses against the inside of the case. The case being made of steel was rusted on the surface around where the spring is designed to make contact preventing a good contact between the case and the wiper arm . . . cleaned it up and the unit is working fine again.
What I am getting at is: If your sender unit is not working, if your resistance readings across it is not a smooth progression back and froth between roughly 20 to 250 ohms rather than toss it and spend the money for a new unit you can open up the unit and clean up those areas and perhaps save the cost of a new unit.
Those of us playing on a tight toy budget can save a few dollars that way.
