with the tan wire disconnected at the fuse panel and the key on you should read past full to 3:00 and with the tan wire connected at the fuse panel and the sending unit tan wire grounded you should read dead empty. Or you could run a ground jumper to the fuel ga plug on the fuse panel. This will verify the gauge readings are correct but you may have a short to ground on the sending unit wire between the fuse panel and the sending unit.
