I had to right a wrong with my cammers fuel gauge. When on empty I would have about a half tank. I had the dash out for some other repairs, and tested the instrument cluster and fuel gauge. Everything checked out and I made sure of a solid ground conection to the dash bezel.
I still had the fuel gauge reading the same. So out came the tank. When the tank was out, I found the PO had routed the sender's ground to an incorrect location. He added a length of different gauge wire through to the inside of the trunk.
I thought I had found the smoking gun with that PO repair. But before everything went back together I tested the sender to see if it's values were correct, and they were. I also made sure the senders float was in the same position as my old sender from my convertible. The floats were identical in the empty and full positions.
With everything back together, I filled the cammer, and it still has the same problem. When reading empty, it only takes ten gallons to fill it.
I plan on removing the tank again and bending the sender arm. I hate to do it that way, but I've run out of ideas on what else could be wrong.
