I think if you use a good quality sealer, and follow the directions to the “T”, it will work for you.

Remove tank, coat at least twice, and let tank stand for a couple of days before the second or third coating.

Take your time!!!! Read instructions!!!! Don’t take short cuts!!!!

We have had really good luck doing this. I even think that a good sealer will seal over one that was not done properly. If they seal over rust, why not other potential problems.

What do you have to loose.

Not sure,just I have been following parts like NOS 37-36 Ford parts for years and not Model A,just wondered if ever shown up.I imagine that a NOS would be rust and fatigue free if stored properly. Some NOS parts were manufacture seconds and needed work when it came to a dealership at least sheet metal parts. I bought a NOS 46 Ford fender once that had an issue when stamping out and I was told parts like this were never tossed but depended on the body shop to address.

I think as a stop gap repair you should add the later 31 style brace. This will help take the pressure off of the tank. Then you can clean up around the old bracket and seal it with "Seal-all" gas tank sealer or the epoxy gas tank repair kit. This will buy you some time but in the end you'll be removing the tank and doing it properly.

Hope this helps The Old Tinbasher

Someone put the dash mount on my 29 Tudor, then soldered the bracket without removing the tank. You can see the thick solder around the bracket, but it's well sealed, and the tank looks like new inside. You can use the large old soldering coppers to safely solder the tank.

I too was a victim of this tank damage due to the steering wheel mount. I did not want to remove the tank either. But in response to some advice (even some scoldings to "do it right" from this forum) I did. It was not an easy task but in the long run beneficial. In the process, since the firewall is part of the tank I replaced all the ignition wiring as well. For the tank I removed the riveted mount and TIG welded the the rivet holes. Then had the inside coated by a radiator shop. Repainted the entire tank with a rattle can. Color is one slight shade lighter but un-noticeable. 3 years later, not a drop leaking.

My restored car developed this same exact problem. I installed the later style bracket from the dash after the problem developed. My plan was to "seal" around the old bracket where it was weeping, but in 2 years there is no evidence of any gasoline weepage around the old bracket. Go figure!? Maybe that will be your easy way out as, so far, it has been for me.

Gas seepage or leaks of any kind are bothersome from a safety standpoint. And doing a repair with sealer does not solve the original leak problem, it just band-aides it! And once the sealer starts breaking down, ya got bigger problems. The easy safe way to fix this is really not easy but is the right way. Take out the tank, and do it right! Everything else in my estimation, just prolongs the agony.

Like many who have posted on this thread, you seem to assume the sealer will break down. Why? I used sealer for the first time over 20 years ago and that tank still doesn't leak a drop. It is one where I used one of my 1931 style column support brackets and then sealed the tank. I expect better sealers are available now than when I did that, too.
A good quality sealer properly applied will outlast us and most likely, the car.
I've also had good success when treating a rusty tank by using phosphoric acid (which leaves a white powdery residue) to clean out the rust, then using the best sealer I can find. In my most recent job, I solved both problems (rust and a leak) at the same time.

I used 31 bracket and sealed around tank bracket with Marine-Tex Gray epoxy. 8+ years and not a drop leaking.

I just bought an NOS Model A tank at the latest Hershey. Until I stumbled upon it, I didn't think they existed.

Was it a '31? or an earlier one?

After the "stop gap" methods; the permanent method. Right TinBasher?

Thanks for the ingenious tip, never would have thought of this on my own!

does anyone have any inside information that someone might manufacture the alternate bracket specially designed for 28-29s?

I did that for RHD cars. The supports are not available (as far as I know) for RHD cars. They were introduced in 1931 and no Model As were sold here that year. My supports work for both body styles. I bought a LHD one and cut it up to make a pattern to have them cast in aluminium which I heat treat so it can be drilled and tapped easily.
If there is a market for what you want over there, I suggest modifying a 1931 bracket to fit, then usung it as a pattern to do the same as I did.

Any Gasoline leakage needs to be fixed right! To me it is just a plain safety issue. The point of leakage is a common one. Using sealers is not the choice I would make. For me the tank needs to come out and that part of the tank fixed right by a pro! Again, gasoline leaks can be dangerous!
