Jim/Dan,

    Another kiss soln is a capacitance probe with an idot light on the panel that warns of high fuel level at about 10 gal in a 12 gal header tank.  Reason- You might slosh additional fuel with changes of A/C attitude if you sense fuel in the overflow tube.  My overflow is at the rear of the header tank and a climbing attitude will slosh fuel overboard at much more than 11 gal indicated in level flight.  just a thought   Don Skeele 235/320
