If I'm filling up out with the semi trucks no I'm not shutting it down, if I'm near gas pumps yes I will..

Heck, in a rare instance, like PPL who like to talk on phones and stuff while refueling, bad things can happen. It is actually a state law to turn off vehicles while refueling, but some do, some don't, except under certain circumstances (Texas Transportation Code - TRANSP § 647.011. Fuel Restrictions). That not bother me as much as the "clowns" smoking while refueling, especially when it gets really hot, and U can just see the "fumes" in the air. We even blew up an immersion heater one day being in a hurry to get lit and not taking proper precautions. Good way to burn yer eyebrows off, lol.

Saw a KC-135 (Strato tanker) being refueled on the parking ramp one day. The FMS person either failed to follow procedure or something came loose, ie., static line. Fuel tanks in belly caught fire and that plane burned to the concrete, with only outer parts of both wings and 2 engines surviving. Talk about a bonfire.
The KC-135, was that in Alaska?

Have had my 2023 6.7l for 2 weeks. Curious as to what others are doing with their engines while fueling up, I see folks all the time gassing up and leaving their engine running. I know these engines use a grid heater and do not use glow plugs, does that even matter in regards to starting the truck? Maybe that’s an old school train of thought in regards to diesels. I also see where the user manual says to limit excessive idle time. The one time I’ve gassed up so far I just let it run. What does everyone else do while gassing up?
4 decades ago, I worked in a high end European shop. The owner hired a new technician who hailed from Romania. When the owner gathered all around to introduce "Stefan". He, the new employee stated rather arrogantly how he "Knew everyzing!".

Giving the new guy the benefit of the doubt and understanding a new environment dynamic, I kind of shrugged off this brag.

I was working in 2 service bays at the far end of the shop where the drive-on lift was located, given that I was the transmission specialist. "Stefan" was working at the other end close to the offices, break room, and parts room. Naturally, I had to walk right past "Stefan" to get to the business end of the shop.

After a week or so went by, "Stefan" was performing a major maintenance on a 1969 pristine Volvo 164. This car sported the Bosch D-jetronic gasoline fuel injection system, which operated at 90 PSI.

One of the steps in this Major maintenance was replacement of the rubber fuel lines at each injector and the longer line going from the frame mounted fuel rail to the injector rail. The required fuel injection hose for this particular car was of a special type which could withstand high temperatures and high pressure.

As I walked by this car one day, "Stefan" was replacing the fuel hoses, using standard low pressure hose like what you would use on a carbureted car with 4-5 PSI operating pressure. I stopped and pointed this out to "Stefan" at the same time as the owner of the shop happened by. Said owner told me to "mind my own business" and to concentrate on my own repairs. I was going to the parts room to grab a part, and as I walked by a while later going back to my work station, I observed "Stefan" reach through the open driver's window of aforementioned Volvo ad start the car. Within 2 seconds, the long hose began to pee a fine stream of gasoline emanating from close to the end by the frame rail.
I said nothing and just observed as "Stefan" took the end of the hose from the steel line on the frame and cut the offending end, and put it back on.

I walked back down to my work area, and heard a loud "FOOM" and a hubbub coming from the stall where "Stefan" worked. The Volvo was completely engulfed in flames. Seems as though that Pee stream had hosed down the adjacent starter. The Service manager managed to grab a fire extinguisher and put the fire out, but it was too late to keep the damage slight.

The hood blanket had caught fire due to years of oil soaking and bubbled the paint off the outside of the hood. The entire under hood wiring was burned to a crisp. All vacuum and fuel, and coolant hoses were destroyed.

The shop's insurance covered the damages and the non-body work under hood repairs were done by the owner and one of the junior techs including installing proper fuel hoses, and as the old saying goes, all ended well.

That Yule time holiday season was my exit from that shop, because I left to open my own shop.
Several years later, I was watching the news. There was coverage of a mechanic burning to death while working on a Mercedes in his shop at his home. It was a gasoline fire. It was "Stefan". He left a widow and 2 small children.

This really got to me because I'd worked with this man... and it really galvanized my respect for fuel fires. So when the sign at the fuel station says to shut off the vehicle.... well 'nuff said.

Just to the south of where I am a running vehicle is not going to be there too long. Heck, sitting at a light is a dangerous activity sometimes. And all those idiots have guns, so not worth it but to let it go.
