That's what I get for using modern electronics (smartphone) to type on.

if you have a co2 fire extinguisher, just blast it into the tank, that will purge it and make it safe. (every farm and shop should have one)
A slight departure, but here's an oldie but goodie.....
A guy jumped out of a perfectly good airplane with a parachute strapped to his back. At the predetermined time, he pulled the rip cord, nothing happened. He pulled the backup-chute chord, nothing happened.
As he fell while holding 2 rip chords, he stared at the ground, wondering where he will meet his demise. Then he noticed a dot getting larger, it was getting larger logarithmically faster than the good earth. Very quickly, that dot grew to reveal that it was a man approaching him in mid air!
Thinking quickly, the parachutist yelled to the man; Hey buddy, do you know anything about parachutes?!?! The fast approaching man with his pants on fire yelled back; NO, do you know anything about welding hydraulic tanks?!?!

I once used natural gas when brazing some refrigerant lines to prevent oxidation and scale inside. As someone already said, you just have to push out the oxygen.
I'd have to think about it some before I'd try it on the Frame/ Hyd tank. It should work fine, it just sounds scary.

I'm going to make a lot of you guys mad by saying this.
Don't worry about heating the crack, burnt oil creates carbon deposits which will weaken the base metal when you weld over it. Don't worry about the hydraulic oil exploding when you weld over it. It wont happen.
I've repaired dozens of these things and this is how I do it. Its worked for loaded crude oil separators, hydraulic tanks, diesel fuel tanks and hydraulic cylinders. Go to the welding supply store and buy or order some X ERGON Black Glass welding rod or POLARIS Brutus rod. I use 3/32" .They are a little on the expensive side, but are worth thier weight in gold for repairs like this. These rods are simply amazing. They will weld through anything: paint, grease, oil, tar, crud, water you name it.
I used them a lot in the coal mines to root out cracks in leaking gear cases.
Fill the tank with fluid.
Wipe as much drip off as you can.
Weld the crack with the Black Glass Rod. Uphill or down it dosent matter. For the 3/32" rods I usually burn at 70 amps. Practice on some scrap of the same thickness to get used to it. These rods have very different characteristics from other rods.
The most dangerous part about hydraulic fluid is the rags you use to wipe the mess up with. Hydraulic oil is candelic. Meaning it burns with a wic, like a candle. You can throw a match into a bucket of hydraulic oil and it will put the match out. Get a decent spark on an oil soaked rag and you'll have a fire on your hands in no time.
PM me if you have specific questions
