gas tank sealer

Hello Ford Barn, I have my coupe gas tank out of the car right now. This would be the best time to seal inside. It is still shiny inside, and doesn't leak. With this new gas we have to buy, what have you had success with. I was thinking of using the red sealer. Any comments, suggestions would be helpful, as I will only get one shot at it...Thanks, Dave
 
Do you have an issue with your tank now, rust garbage etc... If not I would leave it alone, the Model A tank has baffles built in which can effect how the sealer gets applied to the backsides of these hard to reach areas.. There has never been a full consensus of what type to use that will hold up to today's fuels.. It's a risky venture IMO.

We use the stand up in tank filter and some use the filter inside the glass bowl for normal tank function and protection..
Do a search "fuel filter"

Dave,
I wouldn't seal the tank if it is pretty clean inside like you indicated. If the sealer starts slaking off in a few years like some have, you are in big trouble. Just buy a pencil filter that fits in the inlet of the gas shutoff valve below the tank. These work well. If needed, the valve can be removed and the filter cleaned or replace if it gets clogged, which probably wont happen unless the tank is really rusty. Remember, you still have the sediment bowl filter and the carburetor filter to also filter the gas to the engine.

I just got done removing the sealer someone put in my Studebaker gas tank 22 years ago. I've always said I would never line a tank, and I still stand by it. I'd buy a different tank before I'd line one. I run the tank valve filter like Mitch mentioned, even though my Model A tank is spotless inside. Never had a fuel delivery problem.
 
I can't see why you would want to seal it if its in good shape. That being said, I got some of the white tank sealer from Hit N Miss 20 years ago and sealed a tank that was FULL of holes and rust. Has held up for all this time with gas in it continuously. I don't use ethanol gas though.
 
I bought a restored Model A over 8 years ago, and it had the tank sealed by the restorer well over 10 years ago. Not sure what he used, but it has held up very despite living in California, where we have to use ethanol gas. When I first bought it, I was worried about it flaking off.
 
Metal on rifles last long without rusting in tropical areas during monsoon seasons if one places a very thin film of oil on the metal to fill the open metal pores and protect the metal from harmful water molecules which cause ferric oxide.

In high humidity areas, it was never a secret for vintage commercial fishermen to add 30-W oil to their gas to coat the inside of their gas tanks to prevent rusting ....... same proportional mix as that recommended for later advertised top cylinder lubricant ..... 4 ounces oil to 10 gallons of gas ..... then try to maintain a full tank of gas.

Will this work? .......... Well, try this:

1. Fill a mason jar with this vintage recommended gas/oil mix.
2. Add about 25 small very rusty nail brads to the mix.
3. Call in Heaven to let us know when these tiny nail brads dissolve and fall apart.
