Inspect the tank for signs of corrosion. If the transom and stringers need to be replaced, then the tank has probably been sitting in water and will have pits eaten into the aluminum.

if so, then go ahead and replace the tank. If not, then you can pressure test the at at 3 psi ( low pressure) to see if it holds air.

The aluminum tanks usually get damaged from the outside. Epoxy coating the tank helps slow or stop this issue if water gets back in. Here is pics of my old tank which had not yet made a hole, but replaced any way
