Testing fuel tank
I have a 1990 Formula 242ss and sometimes I notice some gas fumes in the cabin. Can someone tell me the best way to test the tank in the boat? Pressurize the tank? See if it holds pressure? If so how much pressure? Thanks for any help

Pressurizing the tank won't work. Most are vented to allow for thermal expansion and prevent condensation.

Hydrostatic- plug vent and outlets, fill the tank until liquid is at the top of fill tube and wait...if it goes down leak
check your vent lines too they could be cracked and allowing fumes to escape

You can pretty much bet on the tank needing replacement. It's 27 years old and, most likely, unfinished aluminum. Not trying to bust your chops, but that's going to be the case.
I have a 1977 boat and when I had it apart for stringers I decided to go ahead and replace the tank. It was corroded badly on the sides and bottom and ready to start leaking. Glad I pulled it.
700 bucks and three weeks time and I had a new tank at the door. I bought mine from Florida marine tanks.
