Doesn't it have a float on a wire? Not the same. The sight guage I
described has nothing in it except gas. I suppose you could put
some chewing gum in the tube to plug it and it might stay full.
Can't really call that a mechanical failure.

Never say never. I've personally seen the failure of just the type of gauge
you are talking about. In a Super Cub. Showed 3/4 actual zero.
