Make sure when you are putting in your bladder that there is nothing sharp or an edge it will rub on. You might find yourself replacing your Bladder more often that you thought if you do not.
JHartz- If you can open the floor up enough to get your tank out in one piece why not get a new Alu or SS one made and stick it back in as a metal tank?
Make the access hatch removable without a chop saw and you will have a long lasting maintainable replacement.
If you open the floor from center stringer to stringer u can pull the tank. There plywood under the tank so nothing sharp down there. Stainless is heavy and alu rots Both are $$$$ and a blater needs no vent and when that go bad there an ez swap.
