P.S. If you have to use the siphon method...

1)grab a hose and a large bucket/container.
2)stick one end of the hose into the gas tank as far as it will go
3)stand up (with your head higher than the gas tank...) and suck on the other end of the hose until the gas is near your mouth... try not to get any of that crap in your mouth.
4)take the end of the hose that is in your mouth out while plugging the end of it up with your finger
5)set your container on the ground (lower than your gas tank) and point the hose into it.
6)let go of the plugged up end of the hose and it should start to drain the tank.

I hate to admit that I know how to do this, but... you don't want to suck on the hose. Easy way to swallow some gas. You blow into the hose. A gas tank is a sealed pressurized system. Blowing into it will increase the air pressure inside the tank which will force gas out through the hose. Otherwise all your instructions are correct.

Don't you lose the sealed pressurized system as soon as you remove the gas filler cap?

Punching/drilling a hole in the tank would be pretty easy. It's highly unlikely that drilling would "cause the car to blow up," particularly because the tank is probably not even steel.

Blowing on the siphon tube isn't going to get you anywhere unless the tube is sealed to the tank somehow.

If you choose to siphon, get a long, clear hose. No risk of getting gas in your mouth if you can see where the fuel is. The longer the tube the easier it is to get the siphon going.

Play-doh around the tank... preferably seran wrapped so it won't get stuck, but should form enough of a seal around the hose and the opening of the tank for enough pressure

Drilling a hole in the bottom won't work to well because there is 30 dollars of gas in the tank so about 15 gallons. That would require a rather large try to fill into and it would be kind of hard to move.

Doh! Forgot to say that you use a plastic "Hefty" bag to seal the hose around where it goes into the gas tank.

Park on a steep hill, punch a hole in the tank bottom and get a few blocks away with a match ready. The rest is self explanatory. 🙂
