Trying to finish up the wings so they can go back to the airport, accomplished a lot of little stuff today. Corrected some wiring errors I had made to the strobes and position lights, and went to work on the fuel delivery system and the venting of the tanks. I am hooking all 5 tanks together to a common air source. All down hill sloped with no traps for moisture or fuel turning to gel. Redone the fuel supply portions of fuel lines that were 1/8 npt, upgraded to 3/8 npt for an easier flow of fuel to the center tank. Probably totally unecessary but sure will eliminate some of the pucker factor when coming home with low fuel in the system. I will be unable to do full flow testing until I get it to the hangar and do final assembly. I feel confident my flow will be quite sufficient.
