You really can't tell me the fire wouldn't go down the lines that run from the pump to the tanks. Those lines are full of gasoline, you know, and oxygen would follow the fire down the lines as well. Besides, those tanks can't possibly be airtight, can they?

Huh? Oxygen follow the fire through the pipes, which are full of gasoline?

Reality doesn't work that way. You watch too many movies.

I never do and rarely see people doing this. Only saw it once I can rememember, about two weeks ago (go figure). I was going to tell the person but it dawned on me that it might be an urband legend.

Bottom line:
1) Engine is running ... things are moving. There is the potntial for static charge build up. Gas pump is grounded. Why take the risk? Ever gotten a static shock when exiting a vehicle?

LOL

You think static is made from the engine running? The moving parts make the static?

Please educate yourself. The static is made by your clothes and/or the plastic materials inside the car.

Q: Engine Running
Why is it dangerous to leave your car running?

A: Many people believe this safety warning only applies to older cars. That is not true. A running car presents a number of "ignition sources" for fuel vapor. The exhaust components of a modern car can literally glow red hot during normal operation. The typical ignition system creates voltages above 40,000 volts.


Bullshit, normally operating cars do not have glowing hot exhaust components.

Tuned cars on the other hand... 😀
 
I always turn it off well except if it is minus temps in the winter. I'll leave it running then just because it is so hard to get it started in the first place but I've only done that a couple times.

actually, this is the time where it would be more likely. Ever notice you get shocked more in the winter when its not humid at all? Well theres more static electricity then. In the summer, i never get shocked. But I doubt it even matters. I never shut off my car. If it explodes ill probably laugh as i die because ive never seen this on the news or witnessed it EVER. Most engine wear occours at startup. Plus in my car (carburated) you burn extra gas when you shut off and start up. So it stays running.
 
I live in So Cal, so it gets really hot over the summer. Right now, I turn off the engine, but leave the key in so I can run the AC.

The static electricity you see in the winter, due to less humidity, has nothing to do with the engine running.
If you want to eliminate that problem, then shock yourself when you get out of the car, then don't get back in until you're finished pumping.
 
The ignorance in this thread is strong. What all you non-mechanics dont understand, is that DC current is traveling through the frame of the car, while it is running. Since there is DC current running through the frame, there is risk of a spark igniting the fuel vapors. How do I know this? a)This is why when you jumper a car, you connect red to red, and black to engine block or frame. b)This is why your self installed juiced up stereo shuts off if not properly grounded the the frame. (Theres no ground in your automobile, its just the black terminal of your battery is wired directly to your cars frame.) So now, what does that mean? You can actually have a fire even if the key is in the "accessories mode only" You must completely remove the key from the ignition to eliminate all danger of accidental fire. Cant believe im the only one to point this out.

But once you stick the nozzle in you car, that should ground your car to the pumps ground. So that instance of putting the nozzle in would be the only chance of sparking, and usually gas is not flowing before you stick the nozzle in. Would this be correct?

Yes, no, and not really.
The primary point of spark would most likely be the point of insertion and removal, and any shifting of the handle during pumping. However
1)The pump handle is not grounded. It is connected via rubber hose.
2)Regardless of gas flowing, it is not the liquid gas to be afraid of... It is the fuel vapor eminating from the tank, in the nozzle entrance, from a freshly driven car. Vapors ignite far easier than liquid fuel.

How does removing the key eliminate ALL danger of accidental fire? Ignorance is strong, you're right about that :roll:

I only speak of accidental fire from vehicle spark. Removing the keys, wont stop you from blowing up if you smoke while refueling. :roll::roll::roll:

I think the problem here is we have made things to safe in our modern society for the Darwin effect to really work. So we need to introduce more hazards to reduce the idiots out there.

exactly. we should get rid of all signs that say "gets hot when heated" and "caution - gets wet when raining!" or such.
 
Oooo...just to fuel the fire, I filled up my Envoy with the engine running this morning...AND I put the gas cap on the handle to keep it running.

Know what? It didn't start a fire and the pump stopped when it was full. Yet another week of life! WOOHOO!!!
 
I'll always turn the car off. I'm not going to risk blowing up myself, other drivers, or some guy's business.

Why waste gas for a few minutes when having to pump gas?

😕

Finally someone asks the right question.

The question should be, why are people wasting gasoline and not, will the car blow up.
 
from what i know, getting gas with your car still running can cause air bubbles in your gas tank and affect how your car runs.
