Topic: Anyone used a bolt on fuel bung?

[Dolomite]

I really dislike the push to latch style caps used on the later 750 tanks. Came across this bolt on setup for a pop up style bung.

Has anyone used something similar to this before? Or is it better to just use a weld in? Also similar to the monza bolt in DCC sells.
