Actually seen a guy use it and it worked way back. I don't know how long it lasted though.
Lol, Sealed a leaking birdbath and this cracked reservoir up with the spray. It worked but they needed several heavy coats ..….
Gas Tank Leak repair what are my options??

I read that soldiers used partly-chewed Tootsie Rolls to seal up bullet holes in Jeep gas tanks and radiators during the Korean war.

When I was doing plumbing a buddy bought a can of it. To test it I put a hole in a plastic water bottle and sprayed it. Filled it up and it still leaked.

If I was getting shot at I think I could find a lot of things to get me out of the situation but something tells me that wouldn’t work for a long term solution.

Lol, Ya' sound a bit skeptical there doogievlg.
All the blackened lines inside are the cracks. The liquid level is at the top white camera flash reflection.....
No leaks under it and it's oil based...……..

The stuff I used was black. Might be a different product and I’m glad what you used worked but mine was useless.
My father accidentally drilled into the tank on my blue 'vert. He used JB Weld. Still holding up 20 years later. But you made a much bigger hole, so YMMV...
Why would you take a chance of putting your finger in the dike. A new tank would eliminate any more problems. The glue may or not hold. When you fill the tank you're adding weight on that problem area. And God knows you won't be close to home when it decides to dump 15 gallons of gas, not to mention the flammable condition of fuel.

Hi Mike,
Looks like I'm going to spring for the new tank.....E Bay 100 bucks or so. Want to do this the right way. Taking out my rear end this weekend, going to pull the tank at the same time. Thanks for your interest.

I popped a hole through the top of my fuel tank years ago. I took a penny and a soldering iron and soldered the penny over the hole. The soldering iron is flameless and wont develop enough heat to ignite any fuel, hopefully.
So the real question is what is your life worth? Sealing up a water jug is one thing, having a gas tank spring a leak around an exhaust pipe is another, just saying.

I wrecked my gas tank putting on an electric pump for the Fitech injector system! Ha ha
I mounted the fuel pump externally on my old tank, and I wanted to use the shortest pickup hose for least restriction, and I wanted the pump mounted at about the bottom of the tank so it had flooded inlet, so I drilled a couple mount holes through the tank seam.
If you drill through the gas tank seam, it leaks! :doh:
Anyway, that was kind of dumb; but on the other hand, I don't care. I got the JB weld gas tank repair epoxy and patched up the holes and then mounted the fuel pump the way made sense to me, and then I let it cure, and then I filled it up with gas and checked if it's going to seep or if it's going to hold.
Anyway, it holds the fuel so - that's the way it goes.
Fitech throttle body works awesome BTW

Exactly, For $100+ why risk it!

I repaired my tank with a sending unit block off plate, neoprene gasket, and sending unit bolts with the o-rings. All from Summit, tanksinc stuff I believe.
I drilled 5 bolt holes and made the hole big enough to put the bolts thru from the inside so the o-rings are inside and nuts outside. Cut groves in bolt ends to tighten with wrench and screwdriver.
They make a threaded ring if you wanted to slide that in the tank, and then bolts from the outside. I had a hard time lining up the ring once inside.
Tried everything else, nothing worked more than temporary.
I have a wagon, no new or used tanks out there.
Pic is test run with cork gasket and metal plate I made. Have since replaced with the parts listed above, no leaks.

Back in the mid 1970's on my 68 charger I used a piece of rubber fuel line cut down the middle and then put a flat washer on top of that and used a self tapping screw to attach them to the tank. I was a poor kid so I couldn't afford a new tank. I forgot about it until I did a full restore a few years ago and saw the old repair. It mad me laugh remembering the things you do when you are poor, but It was still holding as good as ever over 40 years later. With that said replacing the tank is the right way to do it and I did just that during my restoration.
- In 1982, driving back to the lower 48 on the Alcan Hwy, in a construction area a sharp rock punctured the botton of the tank on my 66 Dart; an irregular hole about 3/16”. Jammed bar soap in it to plug until we could get to a town. I did essentially what 68Charger440 did. No new tanks in Whitehorse. Drained tank (that was easy!). Cleaned area around hole about 3” diameter. From the local hardware store, a short fat 5/16 sheet metal screw, a fender washer, and tight-fitting neopreme O-ring against the tank surface, smeared with pipe thread sealer stick. Tightened screw and wiped clean with gas on rag. Let dry. A thin coat of JB weld, let it set up for an hour, another coat feathered out, let harden overnight. I had a spray can of undercoat with me for some reason, and sprayed a coat on for appearance as much as anything. Planned to replace tank when i got home. Patch held, so decided to just replace tank whenever it started leaking. I still have the car, drive it regularly, though not daily. Has never leaked. I will still replace tank whenever/if ever it leaks...
Viewing this thread for the first time. I know I'm chiming in a year later, but have had great success using Plug N Dike powder in the Fire Service handling leaking gas tank emergencies in the field. It is a powder, mix it with water till u get a play dough consistency and slap it on the leak, It hardens from the petroleum interaction.
Some of our handiwork is still holding up.
Hope it helps someone.
