Re: 4207 Fuel Tank Replacement
That's a big undertaking. Been a while since I've worked on a 4207 so I may be mistaken here but I don't think that those can be removed without moving the engines first. Perhaps Waybomb can confirm as he had a 4207 in the past. Pretty sure the tanks tuck under the decks or at least under the side cabinet compartments so I don't think simply pulling up the cabin floor port and starboard will allow you to pull them straight up unless they're only under the cabinets and dismantling those will allow you to pull them up and out.
Have you tried contacting Carver with your hull number? They may be able to offer up some recommendations. You can also ask them who the tank OEM was (probably not around anymore) but there should be a label on the tanks with that information. If you can find a manufacturer that has the drawings for those tanks, that would be the best way to go. One that deals with a lot of marine tank builds might have drawings from either the original OEM or recent builds.
Is it leaking from the bottom of the tank?
Keep us posted.

Re: 4207 Fuel Tank Replacement
It's not a bad way of doing it.
I've seen it done a few times on 53' Hatteras flush decks to get the old Detroits out

Re: 4207 Fuel Tank Replacement
But then again. I never did it
Definitely need more due diligence on this one.

Re: 4207 Fuel Tank Replacement
Another option would be to open top of tank up (if accessible) and build another tank inside the existing tank. Just aluminum and welding... The panels can all be measured and cut outside the boat. I've heard of this done before.
