I had good results with a company called Gas Tank Renu. They have a website. Sent my 1958 Biscayne tank to them and it came back just like new. Only thing I had to do was remove the tank and wash it out good with laundry detergent to remove the gas smell. Let it dry good and sent it off by UPS. If a recall, it cost me around $125.00. A lot cheaper than a new tank. Gas Tank Renu has various franchise locations. I think 4-5 in the northeast. Just another idea I thought to throw out there.
