Ghetto Jet Not knowing anything about this I would fill it with water and leave the hose running in it then attack it with a sawzall.

toddalin Clean it out as best you can. Put dry ice in it and let most of it go to vapor. This will displace the vapors in the tank and the vapor from dry ice (frozen CO2) will not support combustion.

When we used to do underground tank removals at gas stations, the tanks were alwayed purged with dry ice.

I know a guy who was doing that to a flat on a truck inside a furniture warehouse packed full of furniture. When he ignited it the truck caught fire. I don't know if it was too much either, oil leaks or what. They had a fire extinguisher malfunction and almost lost control of the fire which would have cost several million dollars in furniture plus a very large warehouse.

nine4gmc i washed mine out with dawn soap, then filled it with water till it ran out the hole i was welding. i burped some out so i wasnt welding under water, then filled the hole.
my neighbors, we dawn washed/water filled and used the horrible freight air saw to cut a large rust hole out and patch welded it the same method. these were both out of service for a while but had the smell of bad gas in them.

just be safe, think twice before doing anything and think three times while doing it.

In the 1970's

We welded and brazed mant gas tanks we always purged the tanks with carbon monoxide from another running vehichle with a flex pipe off the exhaust pipes. We never had any problems gas could not ignite with out OX. Of course we dreained them also. The guy down the raod tried to cut into our business and blew the front of his garge off and into the streets. He didnt have the secret like we did....

NEW INTERIORS I have welded and cut on tank's many times... I just wash them out really good and get after it... I don't sit it out in the sun at all.... I don't like the idea of it being in the sun before I weld on it.. Heat will make fumes..

Wash it good and you should be fine....

Now I'm not saying it isn't dangerous.. It is... But it's also dangerous to get under a car on stands,, It's also dangerous to stand under a car on a lift..It's also dangerous to drive your family down a street when someone may be coming towards you that has been drinking..


My point is.. Everything is dangerous and some kind of way... Just use you head when doing something like this.. Do your home work to find out what work's, And what doesn't....Be safe when doing any of these things...

JMSTOY Thanks all for the advice! Lot of great stuff here as always. I was actually all set to go, I took a trip to the junk yard yesterday. A perfect size tank fell right at my feet. Literally, it fell ony foot when I was moving some crap out of a blazer to look in. But thanks all, as always. I'll be using this thread before the truck is done, for sure. Thanks!

cutting gas tank......

Hi,ive cut a few tanks in my time,i put a hose in the tank,and let the water overflow for awhile,then,when the tank is full of water,(i mean,REALLY FULL) i cap the tank and cut it using a 4 inch grinder with a metal cutting disc.then dump the water out,let it set in the sun for a few days,and then do the repair.

trees Flammable storage tanks are potential bombs and should be treated as such. Same as "unloaded" weapons: you have to take positive measures to ensure they are. We read about people being killed or injured by weapons and flammable storage tanks on a regular basis and continue to ignore sound safety procedures. I will continue to be a "safety net" when caution is to be strictly followed. I knew a couple of younger guys that were in the business of cleaning flammable tanker trucks and trailers. They had been in business for several successful years when it caught up with them. They had spent the morning cleaning a tanker trailer before breaking for lunch. They returned and started a planned repair when it exploded. Their remains were so jumbled that it was difficult to determine who was who. Never heard the final analysis as to what went wrong, but just another event to learn from.

By the way, radiator shops in my area will not clean fuel tanks. OSHA Snake's head is too deadly for them.

That being said, I totally disagree with the "do not try this at home" mantra. If you have a brain, are thoughtful (like the OP obviously is since he said he realizes the risks) and ask others with expereince how to go about it, then you should be able to do anything. So lets give USEABLE advise on doing it and doing it safely - not "I do it, but you shouldn't". I hate that.
Yeah man its cool!
Look Smokey lowered a spark plug hooked to a live and firing coil into a 55 gal drum half full of gas to prove a point(no fire no explosion) then he lowered a lit propane deal into the same drum(KABOOM!!) proves flame ignition is better than spark ignition any day.
I dont know what GJ.com is,you know sometimes little fish in big ponds can learn a lot.
Ok dissagree all you want! Its your rite,but dont tell the guy to do it............
Its up to him!!!!!!
So maybe you are right,maybe I only have half a brain,but I still got it...use all of it too,,

I've cut and welded a dozen tanks in my time and all I've ever done it is fill them with water until overflowing several times to wash anthing in there, out. Once you've done that nothing is going to ignite no howm no way, no time.

I also aint skeered to weld or gind near gas tanks either. I just finished rebuilding the frame and installing custom exhaust on my Galaxie with the tank half full (see my blog). Gas tanks don't just blow up everyday - or there'd be a LOT less of us doing this stuff....

Of course I'm not kicking safety to the curb, I'm just depositing a dose of reality into the conversation.
