Another CJ Gauge Question

I know that the gauge dilemma has been covered a lot, but I can't seem to find my specific problem and thought I would ask.

For the most part all my gauges work
My problem is that my gas gauge reads half full when empty and is buried above full on a full tank and takes a while before it moves down.

My guess is the sender in the tank is out of calibration. If it is, you get to drop the tank to fix it.

I'd rather be lost on the trails than found at home!

X2 on John Strenks info. He's great ! (kinda like Tony the Tiger)
The parts shop that stocks part for Skylab II will not have parts for our year/model of Jeep
We cannot accurately judge the trajectory of a speeding critter (cat, dog, sasquatch)
Record heat waves and floods only occur when we visit that area
