The sending unit is defective, or the wiring. No signal = "full". Shoebox has a detailed writeup on checking the system:

The sending unit is riveted to the fuel pump support bracket. Many years ago when I replaced the sending unit, it was only available as part of the complete pump support assembly for about $250. Hopefully its available as a separate piece by now. You don't need to replace the fuel pump, but if you do, the sending unit requires no calibration or adjustment.
