I'm about to change all the dash gauges to Stewart Warner Maximum Performance gauges. In order to do this, there is one piece of info I don't have that I need. What are the readings for a full and empty tank of gas on the fuel gauge? Other than that, I think I'm good to go.

 

Fuel level sending unit- full=6 ohms / 1/2=31.5 ohms / empty=80 ohms.
