I know it can cause some issues with gas burners but can you fuel your duramax up while running without any problems?

I would think there will be catastrophic problems gasing up your, running or not, dmax.

 

But if your fueling up with a running diesel, even with a lit cigar, you'll be fine.

I fuel my diesel work truck up all the time with it running in the winter.

 

I always shut my gas vehicles off while fueling.

Lol, living in Minnesota my whole life, nobody (including myself) shuts their vehicle off while fueling in the winter.

I do sometimes if it’s very hot or cold if I have passenger. When I was 17 pumping gas in New Jersey my first job. Most people in extreme cold left their cars running. Lots of the cars had the gas fill behind the license plate. Now days with the evaporation system I guess it could trip a light. I’ve never seen a vehicle at night shooting sparks out the exhaust pipe. I do know vehicles warm up after shutting off. My conclusion is it’s just another useless rule our government likes to impose on us. Maybe someone could explain this to me. When you see a police car behind a car on the side of the road. Why do they point the front end and wheels towards the traffic lane. Instead of towards the side of the road towards the woods?

Stan, I would assume it's because it saves them a split second when they're after the next incorrigible, but for safety's sake it should be the way you've painted it.

The Police are trained to position their patrol car to protect themselves against a drunk bozo  side-swiping or rear ending them while the cop is at the driver's window of the pulled over violator.   The patrol car "aimed" out into traffic provides a protective barrier.

Diesels I don't think it matters.  No EVAP system on board.  Big thing with gas vehicles is static electricity too.  Getting in and out can cause it, phones, etc.  

 

But the bigger reason I could think not to leave it running is crime/theft rates recently in the US.  If its running and the doors aren't locked, you're asking for your truck to go missing vs. if its off, locked and the keys are on you.

The cell phone thing is an urban legend, but everything else you mention is on point.

I've never had any problems with refueling in the cold. Usually the fuel gels up at -40 and your truck never shuts off. In slightly warmer periods, day-20C the retailer may give you a hard time. Sometimes fuel islands will issues you warnings too. 

 

The process is actually safe enough.

Going across the southwest in the summer with the camper in-tow, I'd let the truck run while filling up with the wife and dog inside.  I did this because the RV lanes at Pilot/Flying-J don't have any sun protection, the fill times can be long, and the truck can go from cool to really uncomfortable in a matter of minutes.  No issues in the 10 or so times I've done that with my 2024 and my previous 2016.

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
