I have a slight leak toward the top of the tank which I won't know how bad and exactly where until I drop it. I will also be able to inspect it for overall condition. Has anyone any experience in repairing tanks and who you could recommend? If it can't be done I want to replace it with a NOS or really good conditon original and avoid a reproduction. If you have one I am interested. Thanks all, 518 248-1105

Re: 1964 gas tank replace or attempt to repair.
Mike,
Coupe of convertible? Where exactly is it leaking from? Could in possibly be at the filling neck flange gasket where it attachds to the tank? If it is just replace the gasket. Depending on the interior surface condition (rusty?) of the tank you may want to consider either sealing it or installing a new Quanta tank which fits more or less fits and looks just like the original. Another possibility depending on the size and location of the hole would be to seal weld the tank. CAUTION:You will want to be sure that you flood the tank internals with a non-flammible gas while welding on the tank if you go that route. I have perfectly good original tank from a '65 convertible that I may be willing to part with.
Hope this helps,
James

Re: 1964 gas tank replace or attempt to repair.
Thanks for the reply James. It is a convertable. I am removing the tank Saturday so I will know if it is the filler neck gasket or a hole. The inside of the tank is clean & shiny, no rust that I can see. I prefer to not go with a Quanta so if yours is available I may be interested. I also need to check out the sending unit as the gas guage bounces and doesn't read accurately. Please feel free to call me. (518) 248-1105. Again, thank you, Michael KalogridisComment

If your investigation shows that the tank's integrity has been compromised (not just a leaky filler neck gasket), just replace it - the good reproduction (Quanta) is the least expensive part for its size you'll ever buy. Don't screw with "fixing" or "sealing" it if it has problems - it's a major safety item.Comment

Convertible tanks for C2 are the same as coupe; only the filler neck is different.
I agree with John. If there's any significant problem with the tank, replace it. The Quanta reproductions are virtually perfect. They even include the O.L. Anderson logo (which can't even be seen with the tank installed in the car).
I absolutely do not recommend trying to repair a fuel tank yourself. If it's to be repaired at all, which I definitely don't recommend, many radiator shops will perform repairs.In Appreciation of John HinckleyComment

Re: 1964 gas tank replace or attempt to repair.
I bought a Quanta reproduction for my 68 several years ago and the O.L. Anderson logo looked simular but it was about 75% full size. You can obviously tell it is not original. Just FYI

Re: 1964 gas tank replace or attempt to repair.
I agree with the above posts stating to replace the tank if there's any indication of corrosion. However, in my 40+ years of working on these cars, I can't ever remember seeing a tank that didn't show evidence of leaking at the filler neck gasket. I'm willing to bet the gasket dried out and started leaking shortly after the warranty expired let alone 40+ years later.Comment

Yes, the original style cork gaskets are a problem in this application and often leak. Years ago I made a gasket out of 3/32" Buna-N sheet stock. Then, installing this using new screws with integral rubber gaskets my leakage problems were over for good.In Appreciation of John HinckleyComment

Re: 1964 gas tank replace or attempt to repair.
Removed tank. Looks as though the issue was the gasket. Tank is pretty decent. Will clean it up, replace straps, padding and gasket. This gives me the opportunity to clean that area well, get the rust off the frame and repaint it. Thanks for the help everyone. mkComment

Re: 1964 gas tank replace or attempt to repair.
Michael,
I'd recommend Joe's advice to make the gasket out of the buna N rubber if you can find some withoout having to buy a hole sheet of it. As for the tank straps, I'd reuse the originals. They are already form fitted to your origial tank which will make it easier for you to reposition the tank when you put it back in. I also use a double layer of the insulation material between the bottom of the tank and the frame. The repro stuff seems to be about half the thickness of the original gasket. Use some 3M Super 77 spray adhesive to glue them together.
Regards,
James West

Re: 1964 gas tank replace or attempt to repair.
I agree...The repo pads (insulation material) are nothing but strips of roofing tar paper. In fact it has the even has the lines on it for lining up courses or rows of shingles. Like so many reproduction parts, I used them but I wasn't thrilled about it.

Re: 1964 gas tank replace or attempt to repair.
Thanks James. The straps are really rusty but I may be able to clean, prime and paint them. Do I need to be concerned about correct bolt headmarks, nuts and washers? Same for cross bracket?Filler neck is corroded but original. Not sure I can get it spotless but don't want to replace with a repo. Suggestions on that?Comment

Unless the straps show evidence of heavy, corrosion-induced PITTING, you can clean them up, repaint and re-use them. Even if badly pitted they'd probably be OK but if it were me, I'd replace them at that point.In Appreciation of John HinckleyComment

Re: 1964 gas tank replace or attempt to repair.
Mike,
As Bill notes, the logo stamping might not be 100% correct. I've also read that the logo is rotated 90 degrees from original. If you want the exact same Spectra gas tank, but without the OL Anderson embossed logo, then an e-bay seller has been selling the Spectra tanks for years. The e-bay ID is mqproducts and the cost is $169.95 inc. free shipping. You can buy the Quanta tank with the OL Anderson logo from Quanta for $229 + shipping. I forget the typical shipping costs for Quanta, but it is not cheap and probably depends on which part of the country you live in. And as you probably know, you can't see the logo when the tank is installed.
