E85, almost the same thing %15 gas, %85 moonshine =)

 

you know come to think about it, i havent seen gas station around here in south florida, that still has the one gas line instead of three. but yea i wouldnt think 3 gallons its probably more in the range of say a few drops.

 

You haven't looked hard enough.

 

A lot of places around here, the vast majority I'd say, are on a single line. =(

 

i suggest you guys carry an empty gallon barrel and before you pump it into your car just pump some in the barrel. do it everytime untill the barrel fills up and then just funnel that into your other car that uses low octane gas.

 

What about people who pump low octane after you? Don't they get some high octane fuel for less?

See, it all works out in the long run.

 

I'm gonna throw a match into the trash can next time i'm at the station.

 

I don't know about you, but every station I've been to has bigger than 3/4" hose. 1/2" to 3/4" line is the size of home plumbing lines and would have very high pressure(which you really don't want with combustibles like gasoline). Average Gas Station hoses have more inside volume than a garden hose by almost twice that. Also you have to account for the amount of line that goes inside the pump and to the switching valve which is about another 4 feet+. This still all depends on the pump and the station. Like I said, maybe 1 gallon+/-. And yes, I did the math first thing when the post made. For reference, I used to own a Shell Station for short time. Also, I have seen people drive off with the filler nozzle still attached and you can see the inside circumference of the hose when the safety joint breaks. No urban myths here, just legit concerns for people that I must agree with. I think 3 gallons is pushing it, but you never know

 

I'm going to email Shell or somebody like that and ask them about this. I will report back any info.

 

this has been discussed before.....it siphons it back down to the tank.

and the pump tube is even less in diameter because it is double walled.
the reason the handle is so large is because it has a mechanism that works like a vacuum and sucks the vapors back into the tank. if you cut it, it will be a tube inside a tube. the inner one, with smaller diameter, is the one that gas travels. the outer one is for the vapors.

 

please somebody provide a real explanation to this instead of people giving this kind of advice...

Personally, i wouldnt do something like that for my OWN benefit. Please consider the other people around you...you never know it could be somebody that is close to you could start a fire and....you get the point.

 

ATTENTION!!


okay, i just talk to one of our engineers here. they design plumbing and fire protection piping...anyways according to him, base from fire protection laws, gas doesnt stay in the hose, meaning when you cut it nothing will come out...once the sensor from the nozzle sense the pressure, you hear it clicks. that triggers the shut-off valve from the tank down there and it does vacuum the gas that has left in the hose. You probably will get a couple of drops from the last gas...

i wish he's the one explaining here. i did my best to explain what i found out...

 

Don't ever trust UTI losers!

hahahahahahahah funniest thing i read today
