During construction I calibrated the fuel quantity gauge according to the plans. During phase one flight testing on a high angle of attack power on turning stall I think the float in the tank got stuck somehow. For the next 15 hrs. the quantity on the Dynon read 14 gallons, then yesterday during a flight it droped suddenly to 0. After the flight I disconnected the lead to the sender and measured the resistance on the float (246 ohms) then added 7 gal of fuel, resistance stayed the same. I am thinking the float may have failed in the tank someway. Any thoughts/ideas?
