Unless someone knows a product, may need to see about having the gas tank boiled out or something. Didn't think it would be to bad when I took the gas tank off, but after pouring out the 15 year old gas ( the gas tank was half full) it was nasty and still full of stuff. Any advice? Can a radiator shop clean this? Now that I know this should I blow the line out going to the carb?
Thanks

Thanks, I've called the two shops here in Rome this morning, one shop gets $85 for boiling and lining, the other is $85 plus however many gallons it holds. Before I drop it off, I'll look and see what else is available.

Cheez, I can't believe that, I just called advanced Auto and they wanted $190..   $59 plus shipping is only $11.. I assume that the one I have is considered to have a external filler.

I know you've already ordered it, and it is the cheapest way to go, but, if done right, you may be better off by having an old one cleaned and lined.  The bottom line here is that these things are made from a cheap grade of metal that will, sooner or later, rust.  Replacing it will get you by for several years, but if you keep the car long enough, sometime down the road you'll be dealing with this problem again.  If it's properly cleaned and lined and the outside cleaned and "painted" with a rust blocker such as POR-15, you'll never have to deal with it again.  Eastwood (and other places) sell the chemicals needed to clean/line a tank at home . . . but for the cost of the kit you can have a professional do it for you.

The old saying "Take my advice . . . I'm not using it!" applies here.  I've always just replaced the tank . . . and usually with a used one that was only slightly better the one I was replacing.  But, that's getting old.  If I have the cash, I'll have the next one fixed.
