Whenever I fill up on gas some gas drips out of the nozel at the end of the use of it. This drips on the ground and is unused. I think that there should be something that slides over the opening of the gas pumps at the end of there use. This would stop gas from dripping out. The save of gas would not be huge but with all the people who fill up it would be a few gallons a day.

All mechanical parts fail. A check valve could be installed near the end of the nozzle to reduce the amount of leakage, but it would leak itself after a short time and would also reduce the rate of fuel flow for a given pump pressure. This would waste more energy than the few lost drops could produce.

It may be feasible to relocate all of the inside workings of the pump handle nearer to the end of the fuel nozzle.

I agree that every drop counts to some degree. Not only is the loss a monetary one but also an environmental one too. What if the end of the pump nozzle was encased in a vacuum hose. This vacuum would automatically come on for two seconds after the handle was released. This would suck up any fuel present at the end of the exchange between pump and vehicle. Of course you would run into the issue of who the vacuumed gas belong to but perhaps you could elect to donate the gas in the vacuum to some worthy cause.

Gas vapor reclaimation devices are already installed on pumps in some areas. Like Las Vegas. (Probably Califonia, but I haven't been there in a few years. . .)

If possible the excess fuel could be reapplied to the storage tank.

Better, instead of a vacuum, would be a pulse of air to blow that few drops of gas into the customers tank. The infrastructure for that would be much simpler and regulation friendlier than some mechanism that sucks exess fuel into a system.

Or you could just shake the pump when it's halfway out so that the extra drops fall into your gas tank like I do...

I agree totally with this idea. If you think about it it would save alot of gas and save your paint job on your car, your new pair of shoes, and the environment. a total win win situation for the oil companies and the consumer. The gas that drips is ghost gas, it doesnt exist . if there were such a thing to stop the gas from dripping then the gas would go into the next persons tank. I know of a company developing this exact product. email for support GreenAmericanSystems@gmail.com

Hello World!

I am Jordan partial owner of a newly founded GREEN company (Green American Systems LLC) located in Northren Minnesota. I am posting this profile in response to a topic disscused on this web site. That is, the Dripping of gasoline at the pump in between fill ups. Just about anyone old enough to drive has experienced this problem at one time or another. The question is, is there anyone doing anything about it? Is there anything i can do about it? The answer is YES! Me and my associate have built are company around this concept. (Green American Systems).

For more information, or if you would like to get involved please e-mail us at

GreenAmericanSystems@gmail.com

Thank You For Reading!
