Messed around again today adjusting the fuel float arm to hit just short of full and empty. Flipped the float around in the wire so it sits more aft and that seemed to help getting it just right. It's not perfect, but comes in very close once installed at 30 ohms resistance, which the instructions say is what it's supposed to be at full fuel. Since my quick build wings are vintage, ie 2005, the tanks did not have the anti rotation bracket for the pick up line. I drilled a very small hole in the hex of the fitting and safety wired the it in place. Mixed up some proseal and installed the cover plate and the fuel float. Proseal is the messiest, stickiest stuff ever and gets all over. Guess that's why it works so well. Plan to leak test the tank soon so I can get started on the next one. Sanded and applied more filler to the wingtip leading edge. It's close, but needs a few divots filled.
