72’ seafari tank removal

[Sprunx]

Hey guys,
Derigged and ripped the old crappy rotted console out of my seafari this weekend (its a seafari outboard / cc conversion done by the previous owner). I’ve had a new one in the works for a few weeks now. I pulled up the deck hatch over the fuel tank because I had an issue with water getting in my tank last year. Was going to try and pull the tank out but the more I looked at the more I became unsure if it would come out.... can anybody tell me if they have personally or know of anyone who has removed their tank without removing the deck with it? The hatch opening is definitely wide enough but idk about long enough to lift the front out and slide it out. I find it hard to believe that this is the original tank given its current shape and being almost 50 years old (from what I can see other than being filthy) but the deck is original from everything that can see.
