86 fuel tank removal

[BERB]

I have the same tank as you! :-( used a power washer to get as much foam cut away as possible! Then i used a car door thin metal lock shim used to open car doors when you don't have the key. Its about 18-24" long and has a gap on both sides on one end, I used that to slide it under the tank and scraped away more of the foam and then i put a piece of angle in the fuel opening and attached it to a chain and attached the chain to a 4x4 across the gunnels. I put pressure on it with a pry bar and was able to pop out one end! It is a PIA! however when i got it out i found there were 2 Quarter sized holes in the Tank and I was glad I pulled it. You should be able to get a shim like i used from a boby sop or auto parts store. Let me know if you would like a picture of it and I will send it to you. :-) good luck!
