Applied additional cork to tank area. Positioned and drilled the rear tank brace. Connected Skytek fuel lines and filled tank with 15 gallons gasoline. No leaks apparent after tightening return line joint. Will let it sit overnight before calling it good. Removed old spar root angle. Positioned replacement root nose skin and cleco'd bottom side. Did initial trim of spar root angle. Will wait until fuel is drained to do further work on the root area since the full tank changes the alignment of the tank rib and I need as good alignment as possible on my previously drilled holes.
