Installed the 14 fuel tank stiffeners, the fuel fill flange and the nose rib to the fuel tank skin. Installed the 5 nutplates on the fuel tank guage access opening and installed the fuel supply flange and fuel vent securing tab on the aft inboard rib. I cut the 1/4" fuel vent line to size and put a 37 degree flare on it. I prepped the tank to spar mounting brackets and inboard tank bracket for paint and painted with two part epoxy paint. Plan to install the rest of the ribs Wednesday.
