I installed the left wing tank today. I laid out and fabricated the fuel tank vent line. I will use flex hose for the fuel supply and return lines between the wing and fuselage. I still need to get the correct bolt for the wing tank to fuselage bracket. I need one a little longer and with a safety wire hole in the head. Once I get the bolt in I will drill the hole in the bracket. I have put this item on my punch list so that I will not forget.
