Can JB weld fix a leaky fuel sending unit?

I got my gas tank out of my daily (67 camaro) right now to fix a leak it has when its full. it seeps out a little around the sending unit line. we tried some of this crazy plastic body epoxy my buddy uses at his body shop but the gas ate it alive. I can order a new sending unit but it take a week to get. the sending unit line moves around a bit and its damp near it im not 100% sure its leaking cause there was another hole in the top of the tank but thats all fixed now.

I just want to know if the gas will eat the jb weld like it did the other epoxy i used. Id like to get the tank back in today either way cause i cant have the car down while i wait for the sending unit to come in. but i dont really want to pull the tank again but i will if i have to.

Thanks
Bryan

 

I've seen it done before and will probably see it again. Not saying its right but it will hold.

 

yeah it works

 

yea i know its not right. i will still fix the sending unit down the road when i have a chance. I have to weld up some exhuast for it so i figured i would fix all the gas leaks before i did that

 

There is some type of JB Weld (Marine, maybe?) thats made to work around gas and oil.

 

We used to sell "Seal-All" when I worked at a little hardware store......I used to hear one of the ole' guys there tell customers that he put it on the gas tank of his 70's Chevy truck and that it was still holding....like 6 years later. We sold a lot of it just for this purpose. No one ever complained about it not working, so, I ***ume it did.......I remember him saying it had to be really dry and you had to put quite a few coats on it...letting it dry in between...

With that said, I'd try some JB weld first. That stuff is slick!

 

If your only looking for a temporary fix, try using kitty hair fibergl***(Canadian specific brand?) Basically a long hair fibergl*** mixture that you add hardner to. Clean the metal as best you can with a grinder if a very small leak(**be careful**) or s****e the area and wire brush it clean, use lacquer thinners to degrease the area and mix up some fibergl*** to spread over the problem area. Not a perfect solution but should last you a year or so.

 

My sending unit leaks in the same spot too. Same deeal, on my daily, can't pull the tank for more than a day. I think JB weld is the way to go, gas won't eat it and I don't have to wait a week for it to come in the mail. Seems like were in the same spot, I was actually going to do mine today as well. Deja who??

 

I have used it on cracked oil pans, seems to work.

 

Nope, they sell that **** everywhere, even in San Diego, Mexifornia.

 

I had a rock bounce up,and puncture the bottom of my tank.My neighbor gave me some "Seal-All".Without even draining the fuel,it stopped the leak.I never did pull the tank,never leaked in the six years that i owned it.

 

Look for info on the package of any sealer as to what it is made to do. If it says gas resistant should work fine.
