I replaced my tank - which, coincidentally, was about 35 years old – because I was looking for a source of persistent diesel smell and discovered some pinhole leaks on the bottom of the tank. The tank sat on a wooden platform with no air space or cushioning under the tank. So the pinholes were apparently the result of corrosion from moisture trapped between tank and wood.
When I reinstalled the new tank, I bought some 6”x6”x1/8” rubber squares used to make plumbing gaskets (about $.50 each at Lowes) and installed 5 or 6 of them under the tank to provide an air gap.

When I reinstalled my tank, all the 4 hose connections were really tight....C&C didn't waste an inch on any hose when they built my boat.....the one inch drop in tank height compelled me to either get all new longer hoses or loosen existing clamps holding the 4 hoses to bulkheads....I loosened the clamps....not as neat as before but not as costly and difficult as replacing all the hoses. After I reclamped the tank to its holding station and loosening clamps to make the 4 hoses to connect, I then thought about putting one inch whatever under the tank to bring it back to its original position and the hose connections.....but that's now 20/20 for this genius!
