HI ED : Rumour has it that Eastwood has a tank liner kit that works with ethanol . If you go ahead with it , be sure to keep the liquid moving while it sets up , AND , keep blowing the lines out so they don't get coated over . Hope this helps -- LATER -- DON / Fleet 51
If it's just a couple of pin holes, I clean up the spot and solder it with a soldering iron. Of course, when you go to clean the spot, you are likely to open up a few more. I do this with tractor tanks.
I did coat a couple of tanks with some stuff I got at NAPA......forget the name though. It was in a red can. A quart was about $50. I would try the soldering first.
I have a 51 Chev car and the gas tank had a pin hole in it. I took it to the local rad shop and they just dimpled the pin hole spot and placed a penny over the cleaned up area and soldered it in . Its been 8 years and still ok. When i worked at a GM dealer several years ago i used to repair gas tank leaks myself with a soldering iron. I was nervous my first couple but it became normal operation after a few. Just no open flames or boom.
You can weld or solder a gas tank as long as the cap is off.
I have also heard of sheet metal screws with a piece of rubber under the head to seal them.

Don't try this.
Purge the tank first and weld away with no worries.
Pic below of the tank hooked up to the Japanese Fume Extractor. Then testing with open flame.
Pugs method works well as the exhaust suppresses combustion I have used a similar method piping exhaust in while brazing
It suppresses by removing the fumes completely. Nothing is left to burn. The checking, cutting of tank, and welding was after running the fumes thru and
everything disconnected. Gas fumes are gone completely.
A rag in the opening can work. Set it on fire and stand back. You get a nice show.
Preferable to do this at night. Gas fumes gone completely.
I see a lot of comments based on fear. Knowing what and how to do something gets it done safely.
I did some googlin on this topic before starting. That's why I had the soldering torch tied to a broomstick
when I did the test to see if the exhaust removed the gas fumes. I was also standing behind the corner of the garage.
I'm now confident to do this again with no worries.
To OP: if you follow this method to remove the fumes, you could zap pin the holes with a MIG.
However, when a tank has pin holes, it usually has rust divots all around with thin metal just waiting to break through.
If it is only a few, zap the holes, a bit of grinding smooth,and a coat of paint would do it.
New tank is the best of course. As mentioned, prices are reasonable for tanks.
Question !! When you over rev your engine does it blowup every time? What was Forest Gumps favorite saying?

If you're comparing the internal combustion engine to fumes in a gas tank, then, basically yes, engine "blows up" eight times per rev and the flames shoot out the exhaust valves just as they will shoot out the filler neck if welding on the tank without removing the fumes.
And unlike Gump, I do know what I'm gonna get. No explosions when fumes have been expelled using an inert gas.
It's pretty simple and no running around to locate dry ice. Every one of use has a fume extractor parked in the driveway.
I pulled the fuel tank out of my fume extractor to fix it!!! Now what am I going to do?
There are some sweet looking fume extractors down the street from me at the local GM dealer. I think I see one that would fit you perfectly. You will need to find one of those flexy hose things though.

The bus, but put your bus pants on.

I got one don at gas tank exchange in Mississauga, worked fine for 15 years. The tank had a couple of 1/4 holes in it originally. Only downside is it looked kinda crappy, flat black with some drips here and there.
