After completing the Ailerons, I decided to give the fuel tank sealant another try. I mixed the sealant then placed it into a ziplock bag and cut the tip end off the bag similar to how one might decorate a cake. This method worked fantastic and made the process much more manageable along with less waist of sealant.
I finished installing the ribs in the left tank along with installing the fuel vent line. On the right tank I was able to work all the ribs except the last rib that connects to the fuel vent line (T-1003B-R). I need to fabricate the right vent line first.
