Does anyone know of any company that either has or repairs old/obsolete fuel sending units? I need to replace the sending unit for a 1980 T-Bird w/digital dash option. Its not the same as for the analog-needle style gauge(different resistance). I found only one company that will rewire the reostat, spooled wiring. Years of dirt in the fuel tank tore the wires to shreads. They quoted a price of nearly $150. Unfortunatly Ford discontinued the replacement sending units two years ago.
