I finally got my fuel sending unit installed in the tank today. I pulled up the calibration menu on the gauge and set it to the zero setting. With about 3 gallons of gas in the tank it showed 1/4 tank. With 5 more gallons it showed 1/2. I have a 30 gallon tank.

Question

Is it more accurate to calibrate it with a full tank?

Does it help to adjust the "pot" on the sending unit?

DO they operate linear at all?

Or

Are they just approximations no matter how they are set up?

Cheers,
