MEK (methyl ethyl Keytone ) we will not dissolve the foam and it is a huge health hazard.

One of these work really well!! Don't worry about the mess :)

I made a tool when I removed my fuel tank. Then used a wire blade and sawed out the rest. Finished it off with a jack that finally made it come loose.

Thanks everyone. Looks like I'm just going to have to go Rambo on it. Don't have enough room to get pressure washer in there. I already took the foam out of the sides and tried to use a come along to pull it up with NO luck.

I used an oscillating multitool on low, cut it like butter, but be careful when u get close to the tank

Get it under heavy pressure and let it sit overnight or longer once you’ve gotten everything you can from the sides. I remember guys on classicmako setting up some rigs with hydraulic floor jacks, chains, and 4x4s across the gunnels to put big pressure on the tank and just let it sit. Sometimes they popped free, sometimes people went bigger.

SDS drill with a chisel bit.

I just removed all the foam around my 1986 Whaler Outrage fuel tank and had the tank out in less than two hours. I was expecting an 8 hour day trying out various tools. I wouldn't consider using anything else if I had to do the job over again.

(1) Get an old school hand saw. Sharpen the tip with a grinder and it will saw and slice the foam nicely to the bottom of the tank. Then the jack and other lifting aids come into play.
(2) Tanks with fumes are DANGEROUS. If the tank is to be scrap you can cut the tank and collpase it. Vacume can also collapse the tank some to make it easier to get out when under lifting pressure from the jacks. It does not take much extra clearance to greatly reduce the required lifting pressure.

12” pruning blade on a reciprocating saw.

100 ways to skin that c as t thought, depending on how well it was installed as how wet the foam was.
