even 3 lbs could do serious damage to the tank, the boat, and possibly your body.. think about it that's 3 lbs of pressure for each square inch... if the tank were 50" x24"x 18" You would have 15,192 lbs of force at only 3 psi!
Places that pressure test fuel tanks use less than 1 psi often with the tank submerged to look for bubbles or have the tank in a special box that supports all sides and is strong enough to withstand the pressure
My advice is that you completely forget pressure testing it or having it tested.... just rip it out and put in a new tank n be done with it.
