Help, cut a hole in my gas tank. What is a good patch?

[BMOTOXSTAR]

Here we go,
  You can all laugh, My pal was using a saw's all (that is what us hill bills call them) 
to cut the exhaust pipe on my 73' Rally so that I could fit my new slotted tips on.
Well, he cut a small slash on the top side of my gas tank while trying to cut the pipe.  
   What could I say, he was helping and f-ed it up. I am really upset. I have spent so much time & money on this Charger that the last thing I needed was a gas tank.
I figure patch it with some JB Weld & spray some undercoating over it? 
   What kind of expoxy could I use that will not get eaten by gas?
We put some of that 2 part Marine epoxy on and it did not do the trick.
    The sad part is that I still have to take the Charger to a Muffler Shop to cut the pipe the right way, my pal did not cut enough off and I told him not to try to help anymore.

Remove the tank and the fuel from the tank fill it with water and weld it! Your muffler shop could weld it? If it's original mite be best to get a new tank!

[konigcharger]

being a fuel tank i wouldn't trust and epoxies to hold nearly as well as welding it

how big of a hole are we talking about?

[Nacho-RT74]

I have epoxy right now, but just as temporally fix on a leak I found recently. An earlier leak I goty about 8 years ago was already fixed welding a patch

[bill440rt]

Other than welding, I don't recommend any other "quick-fix" patches. Be EXTREMELY careful when welding, drain completely & fill with water as suggested. Just make SURE you get all the water out again.

BTW, if your buddy was a true "pal" he'd make good on his mistake & offer to replace the tank for you.

I used that metal to metal 2 part epoxy at autozone for the gas tank on my 69 fury.  It held up for the 3 years I had the car.

[BMOTOXSTAR]

Thanks for the help. I purchased some 2 part epoxy from the local auto parts store.
   Since I have to go over the belly of my Charger I will have to take the tank out anyways , so I will take the advice and get someone to weld it, would that type of hole be mig welded?
Could it be soldered?
Thanks
    I was really  pissed at my pal at first but I am trying to get over it. 
That's what I get for not taking it to a muffler shop.

Welding on a gas tank is risky business, even if it's full of water. And many if not most welding shops won't mess with it (at least that's what I discovered after calling around). One guy even sounded as if he was personally offended that I would even suggest it, like just asking about it was like conspiracy to commit murder. I'd be more inclined to go the JB Weld route myself because you really can't blow yourself up with it.

[BMOTOXSTAR]

Wow,
  Even with no fuel in the tank full of water, that is something. I guess the petroleum chemicals must seep into the metal's pores and really get in there?
I believe what you are saying. I am gonna hope that the epoxy holds up.

I remember calling up some welding shops and as soon as I said it was a gas tank they told me with a very quick "You can't be serious?  We don't do gas tanks."

[Rolling_Thunder]

I've seen it done...      I have seen tanks welded - not something I would want to do...     but some places still do it - I will be buying a new one and having it modified for my EFI needs - BEFORE i put gas in it

[John_Kunkel]

The safest metalic fix would be to solder a piece of brass over the hole but I'll side with the epoxy guys, I've used epoxy with success on several fuel related repairs/mods.

[BMOTOXSTAR]

Holy cow,
    That epoxy works great. I bought some 2 part made for gas tanks, balled it up & let it set for 24 hrs and went on a test run tonight & no leaks.
Once again, thanks for all the help.
     I am going to keep the epoxy on & leave it at that.

It should hold up for along time, dude.  Congrats on getting it fixed

[BMOTOXSTAR]

I was really pissed. I have replaced allmost everyting on this car. I could have bought a Survivor pistol grip 73' Rally by now.
When it happened, I felt like "WTF Next"
I wanted to punch my pal in the face for a second then I came to terms. He was only trying to help. Thank god that epoxy works.

[Charger1973]

It works good, I have some on my tank too. 

[BigBlackDodge]

I JB'd a tank and it lasted for many years with no problem...................it was a small-ish hole though.

Dude, bite the bullet and buy a new gas tank... this thing holds your fuel... which is flammable and flames can hurt your Charger especially if it gets engulfed in them.

Buy a new tank.

Maybe Mike will get me one as a Mopar pal gift.
I can see his point, do not mess with fuel, it could cause problems.

I agree on this. A new tank is like what, $125 bucks? Plus maybe a $2 gasket for the sending unit and an hour in the driveway.
Also, YOU don't have to be a millionaire, your buddy does!    His mistake, not yours. What's he gonna say when your Charger burns up when the quick-fix epoxy fails? Will he replace the car for you?     Not trying to be the black cloud of doom here, but this is a MAJOR safety issue.

[BMOTOXSTAR]

Wow,
   Please hook me up on where you found a tank for $125.
I will have to break down and get one.
My pal as it turns out really is not a pal or he would have offered to replace the tank, I would have if the saw's all was in the other hand.

[bill440rt]

OK, so I was a "little" off:

I'm sure there are other companies out there that sell them at similar prices. Search around. I got mine ('69) on a blow-out thru Mitchell Motors, $125 + like $12 shipping. Worth it in my book.

[Nacho-RT74]

those are Auctions, not prices .

[The70RT]

those are Auctions, not prices .

Look back at completed auctions and some didn't even sell. Some only had one bidder so yeah 139-141 and 25 bucks shipping.

I was really pissed. I have replaced allmost everyting on this car. I could have bought a Survivor pistol grip 73' Rally by now.

I bet if you buy a new one then look inside the old one you won't feel like punching him in the face. Maybe just a little  .....have him help you replace it and bring some beer

Buy a new tank.

The epoxy will hold it long enough to save a few bucks up for a new tank. I too would eventually get a new tank but it doesn't have to be done right away. Just put $35/mo. aside for the next five months and come February or March you can buy a new tank and get it installed just in time for the summer shows.

Before I put a new tank in the Challenger, I had a leak and was calling junk yards trying to find a Challenger tank (this was the late 90s) The guy at the scrap yard said they had no challengers in the yard, and asked what was wrong with my tank?  I told him it was leaking.  He said brieng it in and let him look at it.  After looking at it he said" I can weld it up for $20 but you can't tell anyone and no reciept.  I was a little leary but he did a good job.  It held gas until I replaced it during restoration.  I even sold the old tank at Monster Mopar about 5 years ago.  So there are people out there that will do it, but at least this guy diddn't want his boss knowing he was!

[Nacho-RT74]

radiators guys are able to fix it... they did on mine 8 years ago, and will do when I remove the gas tank again soon for the new leak fix. As I stated epoxy works good as a temporally fix.

[788man]

I just went through this with my cj5. It was rusted inside and started getting pinholes in the lowest corner of the tank. I did some research and found to clean it up with a muriatic acid then they make sealant kits that you slosh around inside to coat the tank. You'll be into a $125 tank for $70.

But the bottom line is just get it welded for $20 or spend the $125 for a brand new one.
