Not much progress in the last month due to flight training and. Christmas 2020. I started plumbing the second wing fuel tank tubing. In the process I discovered that the sump drain hole drilled in the completed cover is not located correctly due to the tank not being cinched into position when I cut the hole. I will rivet a circular stiffener around the area and cut a new hole. Probably will do the same on the other Tank cover in interest of symmetry.
