Leaking gas tank question

YellowDart69 said
When I went to move my car, to prepare for winter storage, I noticed a puddle of gas below the tan k[that explains the poor gas mileage]. I have a spare tank, from another '69, that has been sitting in my garage since 1976. Is there a way to check, if it's any good? I don't really want to deal with this till next summer.

Yes, you could temporarily seal up all the holes in the new tank with tape and plastic. Then blow some air into it at low pressure while another person is spraying a solution of water and liquid dish soap all over the tank. Look for bubbles to show up on all surfaces. No bubbles? Then it's a good donor tank.
