As it is an aluminum tank, it is less likely the leak is from corrosion, so maybe a seam or as my steel tank did a contact wear point. My steel tank wore through on the shoulder where it narrows and was touching the inner fender. It would weep and smell of gas in the garage the next morning after filling the tank more than 3/4 full. I was fortunately able to remove the tank strap and move the tank over enough to be able to sand and effect a bondo repair (the stuff specifically for gas tanks) until the next time the engine was out.

Early tanks were indeed aluminum, and the geniuses at the DOT forced Ford to wrap the aluminum with fiberglas as 'protection' against cracking. It is one layer thick and likely has long ago debonded. I would remove ALL the useless fiberglas so the actual leak can be located. Then since it seems small, Devcon or Bondo are both totally fuel-proof when cured- even the witches brew we're sold as "gasoline" these days. A pinhole in our tank was fixed with Bondo 15 years ago and still no leaks. Of course, TIG welding can also be done. Std steel tanks can replace it as well but early tanks are different shape than later ones. See the write-up in your Newsletter a few years ago on what Ted Mitchell had to go thru to adapt an early tank to a later car. Good luck- J DeRyke

Hello,
I got early 71 car and my fuel tank looks as it is wrapped in
fiberglass and
painted black.
I tried with the magnet and actual tank is
non-magnetic; is it aluminum?
Problem is that it must have a tiny leak as I see
one corner on the bottom
always being wet, but it is not enough to actually
make the fuel drip.
Are there any suggestions on best way to deal with this
problem?
I understand one needs to take the motor out to get to the tank?
Is
there a good way to repair/reseal my tank or is the best option to
replace it
with new one?
What is best option/where to buy a replacement tank that would
fit in stock
location.
Thanks,
Robert
