fuel gauge issues

On my 72 ford, the fuel guage will not register past 1/2 fuel when it IS full. I switch out the voltage regulator with no effect. When I grounded the pos wire to the tank it did pegged but did so in stages and slowly. Any ideas?? If it is a deffective gauge and can't be fixed and has to be replaced any ideas where to find a 1972 F100 instrument cluster??

Have you checked out the sending unit.Do you have a in cab tank?Ive had trouble with the rubber sock which goes over the brass float ball sticking on the side of the tank.Thats if of course you have that style tank.

Yeah I switched out the sending unit with no effect. Even when I had the unit wired uo "outside" the tank I couldn't get the gauge to register "full".

I have the same problem with my 72 F250. Never did find a replacement. Now everytime I fill the tank I just calculate 8 miles to the gallon! Dont want to run out of gas or pass a gas station.
