Drilled a 9/16 hole in the top of the fuel tank for the Fuel Tank Vent modification and deburred the hole. Removed the cured fuel tank sealant form the T-1209 Res Sender Plate and the T-1202 Fwd Tank Bulkhead using multiple applications of Poylgone Gel and using a variety of scrapers. There is another SB for the Fuel Tank that recently came out and I'll need to do it in addition to the other modifications. The new SB requires the installation of Doublers to the inside of the Fwd Tank Bulkhead. Deburred the F-01296 Vent Bracket and the AN Spacer 6D for the fuel tank vent fitting.
