Ever wonder how the gas pump nozzle shuts itself off when the gas tank in your car is full? Yeah, I never have either. Until I saw this article on MSN. I guess I just never thought about it. It’s relatively simple though, and pretty impressive considering the ‘technology’ behind it has been around for 50 years. Impressive because there really wasn’t technology back then.
This article also answers some of the other questions you’ve come up with while driving but never thought to actually ask. Anyone have anything that wasn’t covered in the article?
I remember a few gas stations that did not have that kind of nozzle, so you had to listen to hear the gas coming up the spout. That is almost impossible today with so many cars going by the station all the time you can never hear the gas in the spout.
I remember that too Charles. I remember getting gas all over my shoes a couple times when I would space out and let it run to long and the gas would overflow. That would never be allowed to happen anymore because of all the issues with pollution and part of the climate change discussion is even putting some sort of regulators on gas nozzles that keep fumes from escaping! Plus I can't afford to pay for gas that doesn't make it into my tank. Although I won't complain because it's not nearly as bad as it was a year ago.
