Ok i am lucky that its not worse.!!bloody stupid idea
My GTO was stuck in some mud ( sorry guys no pictures ) down to the diff. So we need to jack the car up and get some gear under the wheels - normal stuff. But The jack slipped and dented the fuel tank. It has a small weep and a nice dent.
Now in Aus a replacement tank ( new ) is $520 and shipping one in is worse ex states $700+.
My question is what are the interchangeable tanks . I found a Camaro will it work http://cgi.ebay.com.au/67-69-Camaro-...#ht_500wt_1156
Any other cars ????
Have you repaired large dents in your tank and it worked .
Or i am up for a new tank!!.

I have a small leak in my tank as well.

You can pull the tank and take it to a radiator shop. They should be able to clean it and locate the leak. The problem is that I don't think they can braze it because of the explosion hazard. Might be able to bang out the dent with a brass punch. They have tank sealers that you pour into the tank and slosh around.

I guess you need to find out how big the crack is. I think I'm just going to replace my tank, but it wont cost as much living in the states.

Good luck!

Radiator shop CAN repair the tank in most circumstances. They clean tank, defume it and then welding/brazing can be done. Clearly, one does not braze on a tank that has not been tanked and cleaned of any fuel contaminents.

Depending on where the dent is and how large, you may be able to use one of the suction cups that they use in bodyshops to pull the dent out. Its worth a try. Problem is if your tank has ridges made into it, it will be hard to get it to seal up and get a good pull. You might think this is crazy,but I have heard of sealing up all holes/vents and using compressed air to blow tank back into shape.

i don't think that's crazy at all. i've seen compressed air split a new plastic tank, so popping a dent out is well within the realm of possibility.

i can't for the life of me remember what it was called, but there is an over the counter putty patch for a leaking gas tank. years ago a buddy of mine put a hole in his tank, got the stuff from and autoparts store and applied it. lasted for many years.

Just de-fume and braze. I did it years ago to a tank. Gotta take tank out. Flush it out with water a few times. Then I brazed it outside so if it does blow its only you and the tank, don't do it in a building.
Brazing is the only way to fix it for sure. As far as the dent goes you should be able to reach it once you pull the sending unit. Then pound it out best you can.
I'am sure a radiator place can fix.

Radiator shops don't normally braze or weld them, they don't even bother to get the fumes out. They use a hot soldering copper and solder them. Since there is no spark or flame there is no explosion hazard. On my 73 T/A I had a leak at the soldered joint where the neck joined the tank and I fixed it with a copper and re-soldered the joint.

If you want to weld one all that's needed is to hook the exhaust pipe of a running car to the tank taking the oxygen out of the tank.

I would assume any GM A-body tank from that year would fit. That includes Chevelles, Oldsmobile Cutlass', Buick Skylarks...

good luck.

[rlfonad]

I believe maurauder is correct, expecially for the chevelle tank.

You would have to swap-out the fill neck though ... they are different.

I have a friend that owns a welding shop the repair fuel tanks all the time usually they just empty the tank fill it with an inert gas like nitrogen and weld or solder it up, Although a do have to say it usually for big trucks and diesel which is a lot less explosive than gas. I'm sure if you remove the tank any competent welding shop could fix it.

A friend did that to his 69 Charger's gas tank years ago. Compressed air in the filler neck, sealed with a rag. Got 95% of the dent out.

We use to fill them with water to 3/4 full then pump argon in and then braze them. Argon is inert and does not light up. For the dent, you should be able to get access from the sending unit hole.

here's my input. If welding...rinse thoroughly with Drano...as it will neutralize the gas fumes. Run CO2 thru tank while doing the actual repair.A welding instructor taught me this. For temporary fix...good body filler will seal the leak...and I've seen it hold for years! Just a couple of FYI's. Good luck.
