So I managed to do this twice since I made the thread, both without power tools. Sort of a pain in the ass but rather safe than sorry. First time drained the tank and left it over night to allow the fumes to disperse as BeastTX metioned. Next morning I simply took a brass rod and hammered it in slowly to create a bunch of little holes and formed it in to one big one (junk yard specifically wants one fist size hole, not a bunch of little ones).
Second time around, the drain plug stripped and I had over 10 gallons of gas to drain, so that was a real pain in the ass, specially because I was doing this on my driveway with the car on jack stands. Long story short I did the same procedure, but I would allow a bucket to fill up with gas, plug it back up, empty the gas in another car, and had to do that about 5 or 6 times to get it all out of there.

Key is just being patient, first time I was rushing everything and dropped a lot of gas on my driveway which got pretty messy. Second time around I took my time and out of 10+ gallons, I couldn't have dropped more than 1/8 gallon all while doing it on my back. Brass works great because it doesn't create a spark so if need be, you can hammer the shit out of the tank, specially if it is metal like mine was.
