I am having a hard time believing that....can you provide some source for this info????
Maybe it's just me, but if I can see the gas, then I don't think it is getting sucked back into the pump
Because if I'm understanding you accurately, then I would be able to stand there all day, continue clicking past the cutoff and never spill a drop.
Now that I think for a moment, I do believe at some stations they have a type of "vapor recovery system" that is supposed to pull the vapors back somehow to help eliminate their escape into the atmosphere as you pump....is this what you are talking about???
And, Old Tele man... thanks for the link. That had some good info in it that I'm gonna have to read through again to make sure I understand how the vapor system works.
