Stop what you're doing right now.
You need to make sure the tank is EMPTY BEFORE you take anything off of it.
Wait, I think I misread your post. In that case I'm sorry. If the tanks empty and you have the burst disk off already, good.
I thought you said you were trying to empty it by taking the disk off.
Read the part I wrote about loctite and warm water. Heatgun/hairdryer could work. Be careful if you use a heatgun though.
I'll write the rest of the post in a minute, so check back.
Ok, now on with the edit.
I recommend have a trained paintball shop install this. If you damage any part of the tank (even if you can't tell its damaged) it will most likely be unsafe to use.
If you're sure you need to do this yourself, and are sure you won't damage anything, and are sure you can put it back together the right way again without damaging anything, here's what I'd do.
You have to empty the tank. There's a few options here.
1) Twist it onto a ASA that isn't attached to a gun. It'll spray CO2. Leave it outside for 10 minutes or whatever and then go get it.
2) Put it on your gun and shoot till its empty (probably the least fun choice)
3) Take the air line off your gun, or cause a leak somehow (loosen parts) and then put the tank on there until it leaks empty. Like number 1, probably best to just leave it outside and do something else for a few minutes.
Tanks empty? Good, now wait for it to warm up and then empty it again. Dry ice forms when you dump a tank like that and as it 'melts' it pressurizes the tank again.
Sure its empty now? ok.
Put it on your marker. The 'Top' side of the tank and valve need to be marker. Draw a small stripe on the valve and tank with some paint. If you fail to mark the top of the tank, the anti-siphon won't work. Also, if you put the tank on another gun and it doesn't line up right, it won't work.
The valve might be loctited. Heat breaks loctite. Heat will also make the tank unsafe if you have enough of it. A good solution is to put the valve half of the tank into some warm/hot water. Don't boil it, that could get into the not safe temperature range. Just warm.
Now you'll need a vise, strap wrench, or some other means of separating the tank and valve without scratching anything. Line the vise with leather or rubber strips.
Put the valve into the vise and strap wrench the tank loose. If you dent it at all, throw it away. It has just been compromised.
Once they're separated, clean the threads with a pick or wire brush or something. Don't be rough, just clean them.
Attach your anti-siphon tube. If you have to solder it be careful.
Now bend it towards the mark you made. It still needs to fit through the neck of the tank for the install, so don't bend crazy.
If the tank had loctite, reapply it. Probably red. Put the valve on and give it the proper torque. You don't want to have it come loose, but you don't want to severely over tighten it either. Aluminum is soft and doesn't care for abuse.
Let loctite dry for days before getting the tank filled.
I've probably forgotten something.
