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??

It's not necessary to pull the tank and plug/flush the lines. Leave it connected and it's plugged/sealed by default. How is a welding spark going to get to the gas? If you have a leak? You could bounce sparks off your gas tank all day.

If you have wet gas puddling around, it will burn. If you have contained fumes it will explode!! Obviously make sure you don't have either. If you make sure you don't have leaks, you do have good ventilation, and throw a wet towel over anything that could leak fumes or be vulnerable to melting under a spark, it's just not a big deal!

The original question was about welding a front trunk AC hole. It's not like he's using a cutting torch to cut 1/2" plate right above the gas tank spout. But whatever. Do what makes you feel safe. I just don't like doing a bunch of unnecessary work for no valid reason.

Rand, I could not agree with you more; The input was varied quit a bit. I can see that I would not be in danger on the front or even engine comp, fumes or something extra I coud not see/understand which is one reason I asked to fill the tank first. If I created enough heat to penetrate that far I would not have a front trunk at all. The chance that I have a leak or even a small pool of gas under the tank is minimal as I have changed everything down there and have been under there a couple times this year. and the spark going the one in a million jump to down the opening around the tank to underneath and staying hot enough long enough to spark, it is crazy odds. I just asked in the begining to check prior as I do not think I know everyting. Wet towel ect. to be certain is good enough. I have spilled gas all over me and on the driveway before and I lighted cigs all through the ordeal.. Fumes have to be concentrated and i am bascially outside no garage.

All the input confirmed my original thoughts, thank you everyone.

There is another reason I ask about around gas safety. I loss 90% of my smell sometimes it is better than others but it can be dangerous, I have accidently inhlaed flooring stripper all day and did not realize how much unitl I got sick headache./.
