I had a successful run with the Kingston Gasifier yesterday, but it was leaking gas out the "Vaporizer" or "I-shaped" neck when I went to start the car (I am still getting used to the settings). According to Jim Mahaffey, it should not leak and there should be gaskests between each seam. I disassembled it late last night and discovered that there were not any gaskets there, just Permatex. I cleaned everything up, made new gaskets and reassembled the neck and bowl last night.
Now I need to paint it. Does anyone have a recommendation for a paint that will not dissolve when in contact with gasoline? Thanks.
The only way that I have found to make the paint stick when gasoline gets on it is to bake it. I spray the carb with enamel then bake it for 15 minutes at about 400 degrees. The wife is not happy with me doing this but the paint does not seem to dissolve when gas gets on it and she understands the need.

So that works OK for a carb, but what can you use for a gas tank (on the outside)?
When I use my wife's oven to bake things or dishwasher for carb and other parts (works great by the way) I find it's easier to ask forgiveness than permission.
My wife says I can use anything in my garage. But stay the bleep out of her kitchen. I did have a fleeting thought about using the KitchenAid dishwasher once for carburetor cleaner but I got over that. Boy that steam unit would've worked beautifully. Sometimes I think even the government is afraid of my wife.
For baking small stuff like carburetor parts, you can just go to the local Goodwill store and buy a used toaster oven. Dirt cheap and you can keep it in the garage. Your wife won't want to borrow it after you have baked a few paint jobs anyway.

Lacquer seems to hold up. No wife to worry about so I have melted tar and dried paint in the oven. With the back door open never really noticed that bad of an smell.
"Hot Fuel Proof Dope" (if still available, been a long time)used by model airplane builders should work.
I was going to suggest the same thing, model airplane fuel is mostly methanol with anywhere from 10 to 30% nitromethane blended in, so modern gasoline/ethanol blends shouldn't be a challenge for "Hot Fuel Proof Dope".
Howdy Jim,
Here's a fool-proof product that comes in a variety of colors. It works! You can find it offered by loads of vendor sources if you goggle it:
Moeller Color Vision Engine & Fuel tank paint
Here's the OEM website:

or here's a vendor example

P.S. You don't need to find an antique 'Easy Bake Oven' on eBay either.

Thanks all - I just ordered the Moeller Neptune Black locally! I really appreciate all of the creative ideas. Let's hope this stuff works.
Can't believe nobody mentioned POR-15. This stuff is bulletproof on a carb.
any 2 part urethane enamel will not be affected by gas. No need to bake though you can just mix as directed and allow to dry, the hardener will cure the paint as if it was baked. So you don't need a big oven to put the gas tank in.
On automobiles the paint is baked on the assembly line, once put together plastic parts and others can't take the baking heat so now a hardener based finish is used to equal the qualities of the original when repairing it. Lacquer will redissolve if contacted by most solvents.
You don't see any effect from gasoline on todays cars if it has gas spilt on it.
Les, I used Rustoleum Cold Galvanizing paint on the gas tank on my TT several years ago. It has held up very well. Just a thought. Dave
I've used plain old black Rustoleum on carbs. No problem when gasoline gets on it.
Most professional paints have specific instructions on "baking". Usually somewhere in the 130 to 150 degree F range for 15-30 minutes...
With that said, I have never had any issues with properly applied DuPont or PPG paint products. If you are painting a fuel tank that is galvanized, you need to use the proper primer. I believe that new tanks are galvanized (zinc coated steel) and that some original tanks may be made of terne-plate (solder coated steel).
I picked up a almost new wall oven at a garage sale and installed it in my shop (only needed a 2 pole 30 amp breaker and 10 gauge wire). Up till now I have used it for baking cores for sand casting, preheating rods and caps etc. for babbitting. Now I see that baking painted parts might work too. It will go to 500F so might even work for small powder coating.
My problem is I have a speedster gas tank and a Stanley gas tank that both need painting this winter. The Stanley had been painted with some kind of Urethane but it was peeling around the fuel filler. Maybe because it was a copper tank and wasn't prepared properly. I don't know.

Carey abate is resting in hospital from injuries at home. Cause has not been determined but wife is prime suspect. It is said that Carey was going to use some of the kitchen or laundry equipment for cleaning Model T parts and that did not go over to well with said wife. He is expected to make a full recovery.
" WISH HIM A speedy recovery"
Just kidding Carey

There's a good reason Peter, nearly all auto manufactures now use the new generation of waterborne paints. It contains a suspended latex core which is highly resistant to fuel & acids. I currently work exclusively with PPG waterborne Aquabase & Envirobase products. Amazing stuff.

Hi Jim,
I have a 1911 T and I'm running a 5 ball carb, and it leaks sometimes. My engine pans are painted with VHT Epoxy Paint out of a spray can.
The paint is self priming all weather rust and salt resistant. Once it has dried and cured the gas leaking doesn't seem to affect it.

I also use this paint on my engine. You can spray it and touch up any place anytime, and it works well.
Hope this will help you.

Snyder's sells gloss black lacquer for carbs.
