Default gas guage readings

put in a new fuel tank in my 71 270/350. I tried 3 new sending units, the guage shows half when in fact i use only about 5-6 gal of fuel, checked ground all seems ok, pull off round plug frm sending unit, guage goes to beyound full, pull off square plug, nothing happens, the gas guage was always fairly accurate with old tank and sending unit. Im original owner 73000 miles, car is all original. Need some advice to correct, thanks

Get an ohm-meter and check the resistance of the sending unit. It should go from almost zero ohms at empty to around 90 ohms at full.

What happened to the original sending unit? Does it no longer work after the tank swap as well ?

Thnaks for the help, the old sending unit was accidentally discarded, I broke my own rule about if you want to keep it, grab it right away.
