There is a procedure to bench-calibrate these things. Involves pulling out the sending unit/float, checking the ohms at the top and bottom of the swing, measuring the tank dimensions, and then carefully bending the float rod so that the final "stroke" is optimized. It sounded too involved for my tastes (I have other things that I'd rather take apart and tinker with), so I've just become accustomed to making a hard charge for a gas station when I'm at 1/2 full.
