W/ Penny's help, I sealed the baffle plate onto the tank assembly, per the instructions. Attached the T-412 Tank attach brackets, and cleaned the outside of the tank. Installed fuel tank cap. Before performing the sealing, I reaccomplished the continuity checks on the capacitance probe and verified the fuel vent and flop tubes were open by blowing air through them. Also, did one last visual inspection of the tank interior.
