For what it is worth I have welded on gas tanks before, have found that it
can be done with the right precautions,,,,,,,what has worked for me in the
past was the water rinse, and then to put a hose on exhaust of a running
vehicle and pump it into the tank, I said weld, but was really brazing with
brasse rod, have also known of friends that use a soldering iron and
soldered the holes shut, but that is not my method of choice,,,,,,,,

A while ago we had a long discussion here about repairing gas tanks, which
we concluded *can* be done--if done correctly. If not done right....I'm
forwarding the below story from the current Rock Auto Newsletter.
Thanks,

============
"A friend of mine visited a car wash after we had just upgraded the
exhaust system on his 1991 Dodge Spirit R/T. The exhaust caught on the wheel
positioning guides for the automated carwash, pushing an exhaust clamp into the
gas tank and puncturing it. In a matter of a few miles he went from a full
tank to barely making it up his driveway before running out of gas.
"My friend had just purchased a MIG welding setup, so we decided to fix
the hole by welding it shut. We removed the gas tank, filled it with water as
much as possible using a garden hose, and rinsed it carefully. We couldn't
fill it completely with water due to the positioning of the fuel filler
neck, but figuring we were safe, we settled down on his front lawn to weld
the hole shut.
"As soon as he pulled the trigger on the welding torch there was a sound
reminiscent of a fighter jet blasting overhead just over the treetops. I had
been standing, but when the noise stopped, I was laying on my back and
couldn't recall how I'd gotten there. My friend was also flat on his back,
welding torch still in hand, looking stunned. His neighbors came outside and
were all looking around wondering where the thunderous noise had come from.
"Apparently the small space in the tank that was not full of water had
sufficient fumes in it to ignite causing the explosion. The 16 gallon gas tank
had emptied itself completely of water in a fraction of a second, leaving
only steam wafting out the filler neck hole. It had also doubled in size,
expanding like a balloon, but fortunately hadn't blown to pieces. We avoided
any injury beyond the ringing in our ears and wounded pride.
"Needless to say he bought a new gas tank and we never attempted to weld a
gas tank again.
