The fuel sensor calibration took longer than I thought, as I originally calculated my set points assuming I had a16 gallon tank. In actuality, mine measured as having a capacity of 14.2 gallons. It must be that the angle of the tank in a tri-gear reduces the capacity from the tail dragger configuration. So I had to drain the tank, recalculate the set points for the Princeton capacitive sensor, and configure it a second time. The procedure is very easy however.
