I've never heard of a a good repair approach but maybe others have some ideas. My suggestion would be to find a good used tank.

Wow you must have found a tough branch to puncture the fuel tank!! I'm with gpt, don't know of any good fixes besides maybe some type of epoxy that can hold up againt gasoline??
I think I would by a used tank myself to save the hassle in the long run.

You could try to plastic weld it, but I may just be easier to buy a new tank and not have to worry about a patch. I would hate for something to happen.

Flex Seal??? LOL.  On the commercial they use it to make a boat out of screen door.   Surely it will fix a little hole in your gas tank... right?   

 

I saw it on TV. It must be true.

Ha I saw that too make a submarine out of a truck. But I think the gas would dissolve it since its a soft rubber compound. Gas eats duct tape found that out it eats the adhesive as well

The only way to plastic weld it with success,  is to use a  thermoplastic welder. You have to determine what type of plastic it is, then purchase the correct welding rod. If you don't know what type of plastic the tank is made of, you will have to try a few different welding rods to see which one adheres.  My best guess is that the Tank is either HDPE or Polypropylene.  I have one of these welders which can weld most any of the popular plastics. I recently used it to weld together side by side my trailer ski Glides which are HDPE, and the weld is as strong as the glide.  This can be used to weld any of the plastics on the sled, if you need to. Just have to know what the plastic material is.

well whats the difference between a soldering gun an a thermos plastic welder? beside the obvious like the name an obviously one was meant to do the job an the other is meant for soldering wires. But they both heat up with out using a flame so is it possible to use a soldering gun instead? since its -24 or something like that outside an I don't feel like driving to get a thermo welder

I have used a soldering gun to melt cracks back together on my 72 Olympic back in the day, you just have to be careful and not go all the way though the tank.

Not as good as new but it worked for quite a while. Used tank is the best way to go. Craig's list, Kiji, ebay...should be pretty easy to find one

I worked in plastics injection molding for a few years and as ultra rider mentioned, plastic only likes to stick to like plastics. Poly to poly, acetal to acetal, nylon to nylon.

I agree it is most likely a polypropylene tank. I've never plastic welded, but it makes sense so long as you don't burn through it.

Plastic welding works similar to 3d printing. Melting a little plastic together at a time to achieve the desired thickness without buring or warping it.

With plastic it's all about keeping the temperature correct. Poly melts just south of 450degrees F.
