I'm also using the Brewer's Hardware housings with full ferrules. I want them welded as close as possible and will remove any excess from the inside of the keg. Even if there isn't any sticking through, it will be fine. Just need to weld them above the line where the false bottom sits to prevent creating a route for stuff to bypass it.
I had to use straight elements as the curvy ones wouldn't pass through the housing.
