I?m wondering about the sealing process of the nutplate in the fueltank rib. I get the standard sealant under the nutplate and sealing the rivets like anything else, but specifically I am thinking about the threaded cavity. Is the screw/bolt providing sufficient sealing or is sealant added into the thread as the bolt/screw is inserted and tightened? The only other way I can think of doing a seal would be to create a sealant ?bubble? on the nut side that provides room for the screw to insert and go past the nutplate but not penetrate the sealant. That sounds a little far-fetched so I wanted to check how I should be doing this. Specifically it?s the nutplates and screw for the fuel senders.
