This, gone are the days you can siphon gas out of a car, any car. Since like 1985 or so. Gas tanks do have drain plugs at the bottom, usually.Attempted this. Once the hose gets to the fuel it meets resistance (maybe from fuel level float?). Without the pump line well into the tank, it is futile.
OOPS, my comment was before reading this.Any modern car(at least in the US market) is equipped with a roll over valve in the gas tank filler neck. That's why you can't siphon/steal gas out of them. It is designed so if you flip your car on its roof in an accident the gas doesn't pour out on the ground and possibly catch on fire. It also prevents gas from being siphoned out the filler neck.
I'm guessing that most of the people telling you to siphon/pump it out haven't siphoned gas out of a car in a pretty long time. If you don't have the ability to drain it at home get the car towed to a shop and have it drained. You can also disconnect the fuel rail and power the fuel pump and pump it out but that's a whole different can of worms.
Here is a short video explaining what I'm talking about. The green ball in the filler neck. It's not a Lamborghini but the same principal applies. Also, I don't recommend removing the ball like he's talking about in the video. It's a safety feature.
Good luck. Let us know how you make out.
