Mr Ashley as he almost always does nailed it right on the head. Zenchal26 came up with one fix.

If it's a factory style sending unit and float you should be pretty close but on after market units you have to make some adjustments to insure that the gauge reads correctly.
Mainly the travel of the float on the float arm has to be unimpeded in the tank and it needs to go through it's full travel. If the float hits the bottom of the tank it won't show empty if the float hits the top of the tank it won't show full. If the float arm is too short it will stay on full too long and then hit empty too soon.
