Welding Saftey around Gasoline? Options

[detoxcowboy]

Ignornat questions but..

When welding in the front trunk A.C. hole is it safe not to pull the gas tank? Full tank gas better?

When welding in the engine compartment (shelf below battery where fuel lines have to be disconnected as they pass through that shelf) what do you do with open fuel lines, cap them? wet towel? Engine will be pulled so I could not just leave them connected unitl I finished??

I have no problem smoking around gas just welding is a little hot spark??

Echo Troy. Simple, no worries. Throw some wet towels over what scares you.

Keep ventilation open!

You wanna talk about real freaking out, my dad used to weld on gas tanks. He would hook a tube from the exhaust of a running car into the intake of a tank, let that flow a bit, and weld away.

You do the same thing with aircraft. They call it gas-freeing the tanks. Blow enough air through a tank for a given period of time (depending on tank size) and fuel used. Viola! It's safe to weld on.

I knew a guy who would let a tank basically dry out for a 1/2 day, then, with a lit torch at arms length, go to the filler neck. A flame would shoot out for a second (read that: explode out). No more vapors. Safe for welding. THAT was a little foolish for my taste.
