N-DAP Diesel Pump

On our garage forecourt there is a lot of spilt diesel, which causes a lot of slippery problems. Especially dangerous when on your shoes, I am told as they slip off the pedals. If the nozzel was made similar to washing machine liqued dispensers with a double cylinder pourer, the inner one not quite as long as the outer, the outer one would catch the spills, if it also had an air suction devise on the outer one, which only worked when the handle was pressed to release the diesel, it would suck any spills.

I have done a drawing but dont know how to load it.

Bris: If you can make any sense of this I wondered if you might help me out, please. Thanks

       Take shoes off to drive.

       (Some recent debate in UK to the effect that driving without shoes could be construed as illegal.)

       I can feel the pedals that way better. You wanna make me BUY shoes?   

       Croissant for anything that reduces wastage of fuel and improves safety.

       Do you want me to host your drawing [gizmo]?

       //you wanna make me BUY shoes?// If you can afford to run a car, is that such an unreasonable demand?

       I see problems with metering as the excess fuel sucked back would not be delivered into the fuel tank, yet would be measured.   

       re shoes: Hot and humid, so prefer open sandals without socks.

       neelandan: plenty good shoes drift by daily in canals if money is tight. Can be fished out with a shopping basket (also plentiful in canals) if a net is an expense too far as well.

       Not in my part of the world.

       Here in Virginia, U.S.A., we've recently repealed a law that mad it illegal to operate a motor vehicle without shoes. Sometimes I wonder if lawmakers have too much time on their hands.   

       [neelandan] "I see problems with metering as the excess fuel sucked back would not be delivered into the fuel tank, yet would be measured."
If the fuel is going to spill anyway....
  

       An advantage to [gizmo]'s idea is that the outer spout could create a vacuum seal around the gas tank opening which could prevent spills from 'topping off' the tank.

       Based on description, this type of nozzle was done for @10 years in late 20th Century, at least in California. One hose to giveth, one to taketh away.

       Barefoot driving is illegal in Nova Scotia, Canada.

       Oh yeah, [thumbwax] those ones with the big, huge, ripply, vapor recovery jacket thingies, right? The thing is that they seemed to cause more fuel to be dripped upon the ground.  I recall sitting at a station in San Rafael watching a hapless motorcyclist trying to fuel up with one of those bulbous things without dousing his bike.  He wasn't very successful.

       All he needed to do was pull the sleeve back, same as if he was going to fill a gas can - they still use the sleeves - just not the double-hoses. I believe it's still illegal to drive barefoot in CA.
thumbwax, Apr 11 2002
  

       No, it's not illegal to drive barefoot anywhere in the US! See http://www.urbanlegends.com/legal/driving.barefoot/driving_barefoot.html Some states respond they recommend shoes, but I've also heard many driving instructors and other officials recommend taking impractical footwear (like high heels) off to drive. I'm on an active mailing list of people who go barefoot around the world (non-fetish!) and while we don't have members in every country, we've never found any place where it is illegal to drive barefoot.   

       I think a no-spill pump is still a good idea, because any footwear (or lack thereof) will slip when oily, and also all the spilled diesel is of course harmful for the environment. Don't know if your design works but yes, stopping spills is a good one!
