I posted earlier that one of my 8-year old 100 gallon aluminum fuel tanks began to leak.  I also had two boatyards estimates of $20K which involved removing sliding glass door, dinette, galley, AC, floor panels and then port engine to get to leaking tank. I bought a Makita 10-gauge nipper (like electric hole punch) and a Kobalt skilsaw and cut the tank into small enough pieces to remove.  Took about 25 hours in a confined space (got $28 selling aluminum to recycle place).  Will be installing a Moeller 50 gallon poly tank (that I hope I will be able to fit).  BTW - as I cut the aluminum tank and got to place where it was leaking, I found a steel washer....with a perfect washer-shaped hole.  Not sure how the washer got under the tank.  Galvanic corrosion is nasty and expensive!
