Best stuff to patch hole in gas tank?

[Kenny_McCormic]

Put half a tank in the rage today, got home smelled gas and found a slow drip, rubbed wet area down and it became a spray , after jacking it up and getting a couple gas cans and a catch pan ready a screwdriver turned it into a ~5/16 hole .

J-B stik or other epoxy putty?

Drive a bolt in it and use seal all around it?

Silicone and a bolt?

The tank is solid other than this spot, it got dented in by something and that took off the undercoat, Michigan did the rest.

is it a plastic tank or a metal tank, i would be weary about driving in a bolt, if it metal you could rivet on a thin plate and seal it up..

id be tempted to take it out and weld it

 

[KieranM]

never welded on a gas tank, my brother welded on a diesel tank, but if you do, make sure you leave it sitting for while for everything to evapourate, we dont want any accidents happening now

acctually u fill it right up as u will never get all the fumes out without alot of work
petrol will only burn as a vapor so if it is full it will not burn

your nabour did it with a truck tank (deseil of corse)
the deseil was acctually coming out while he was welding but no fire

i know that if you have a half empty tank, you can fill it with co2 to get rid of the oxygen so no combustion will take place, but with a full tank??? i dunno i would not like to try it

never heard of the c02 thing but my theory works but be buggered if im trying it

I would be cautious on these grounds boys, I have heard many stories of welders losing digits/limbs/lives welding gas tanks. I would fill it with 100% Water, if you are arc welding(MIG, Stick, Tig). It should then prevent any unwanted explosions. But still I would be weary of it, wouldnt it just be easier to buy a new tank? I mean, what does one run for nows days, $100?

I guess some of you guys are not familiar with my automobile.

There are few things I take pride in, high on the list is never going to the burn ward. Pulling the tank to fill it with co2 and braze it would be a lot of work for a $600 car that I will hopefully sell in a few weeks.

Good Idea... I hear its quite painful when they have to debreed the burns... ouch...

Started picking at the hole to remove all the bad metal, ended up with a ~1" by .5" hole. Went to NAPA and bought a tube of JB WATERWELD epoxy putty, they claim you can use the stuff on a fuel tank while it leaks. Wire brushed the area pretty clean wiped it down with brake cleaner and cut a little chunk of brass screen to cover the hole. Then I glued on the screen with a bead around the hole, put more glue over and around the glued screen where there was tank left underneath, waited a minute so the screen wouldn't move and filled in the hole.

I guess that's a fix. I was going to suggest some epoxy, sheet metal, and pop rivots. Drill out tank and plate, put epoxy around hole, pop rivot sheet metal on. But that stuff should hold.

Should hold more than long enough to sell the POS and find a decent CRX or Civic.

Not for ricing, I just want a small fun car that's easy on gas. I can't to run a camaro or somehting along those lines, I would be buying tires weekly and getting 6 mpg. Thinking realistically, a lightly modded subcompact is exactly what I need right now.
