86 fuel tank removal

[jetblue319]

Working on my 86 stepliift, i started removing the factory fuel tank so i can have it pressure tested for leaks. I scrapped off as much of the foam around the tank and removed the two wooden floor supports (2x2) which were nailed in with rubber spacers under it. i power wash to remove as much of the foam around tank (messy). the tank wont move yet. this weekend i will use a Eng lift or come-along to lift the tank up slowly. I got as far as i can go around the tank. i enclosed a few pictures, will take some during lifting.

how about using a piece of cable and a couple of handles to saw the tank free

EDIT: I guess it would be about impossible to get it under the tank

A couple of guys here had done that same job already. Maybe they will chime in and tell you the best way to get it out.

I did saw along the outside of mine with a handheld pruning saw, but no matter what, you will still need a come along to break it free. Run a 2 x 4 across the gunnels to support it, and you should be able to break it free. Good luck.

I pulled mine with the cap off. I used a chainsaw around the edges and no luck. I was lifting the back of the boat off the trailer. So I tear the front bulkhead out and go under the tank with the chainsaw as far as I could. My saw has a 22" bar. Try lifting again and still lifting the entire boat. So I turn the boat uphill put the plug in and start filling it with water while the back is hanging by the fuel tank. Then I said to hell with it and start driving wedges under the tank. I begin to hear something ripping and panic. Before I could let down on my winch the whole boat dropped onto the trailer and my fuel tank was floating in about six or eight inches of water. Turns out the foam itself ripped apart. Now this is with the cap off and a bulkhead ripped off.

well i having no luck with this fuel tank removal, i broke off the fuel tank outlet, and the fuel tank inlet is slightly crush, the tank area around the inlet flexes, but that's all i get. i dont want to remove cap, or cut any of the stringers of frame. last hope will be to fill tank with water to removal any gas uels and cut tank open :( any another ideals out there.
