You can't from the filler.
From what I've read so far, it's not easy anymore. I've read descriptions of screens in the filler neck or at the tank that prevent a siphon tube getting down to the gas level.
So, who has siphoned gas from a newer car ? How did you do it ?
......... and no, I'm not asking for the purposes of ripping off the neighbors in the middle of the night. Thank you.
How modern are we talking here? I siphoned gas from my old '05 Nissan Quest. There were obviously a couple valves in the filler neck, but a relatively narrow and stiff tube got past them.
