Stop in for a cup of coffee

So I was told a story from an old mechanic. Gas tank was leaking on a customer's car. The old shop owner told him to fix it. He didn't know how. Old guy showed him. Start the car on the lift, cover exhaust with a hose, feed other end in gas tank filler neck so all exhaust is blowing in the tank. Grabbed the welder, and welded the tank, right there, while running with gas in tank. He freaked. Old guy says, won't blow up without air, the carbon monoxide will not let it ignite!! This person never tried it himself, was a mechanic his whole life and 100% honest. I would never, but it is said to have taken place. Scary ****

Teamster mechanic mentor of mine and long time co-worker of my father tells me one day "Fill the diesel tank all the way to the top. Use 1/8" 6013 welding rod, set the arc welder a little on the hot side and haul ***." I watched him use this technique on a skip loader tank one day, vertical crack in a seam. Started at the top of the seam and hauled *** down the leak. Little jet of flame now and again. I've used the auto exhaust and oxy acetylene on motorcicle tanks. When my Yota 4x4 tank got a rusty pinhole in it I drained the tank, sanded the paint off acetoned it to get the remaining oils off and used an industrial epoxy we had at the rock farm with it's fabric reinforcement material.
