The fuel sender unit in my 1980 Spitfire is not working like it should. I suspect the float is full of fuel. I've eliminated the gauge by simply touching the wires together at the tank, so I know the guage works. When off, the gauge goes to empty. When on, it jumps right on up to full -- and I know it's not full. I understand there are floats for other cars that will fit in my car, but I don't know what those models are, and I don't want to remove the sender unit until I have a replacement. Anybody know? And does anybody know why I can't put a right-side-up picture of my car in this forum? Everytime I try to import it, it's upside down. Even when I turn it upside down to begin with, it's still upstide down. Thanks!
