Refueling

[tonwe]

I've done a search and the one thread that popped up didn't really answer my question; is it bad to refuel our 6.0l's while leaving them running?

In the summertime especially I always leave the 6.0 Excursion or 7.3 Dually running. With as big as the fuel tanks are (44 gal & 38 gal IIRC) and as long as they take to fill up, my wife and son would melt if I shut off the A.C. I can't say if it's good or bad, but I haven't had any issues from it that I'm aware of.

I never shut mine off, same with my 7.3 I had for 2.5 years. I don't see why it would make a difference? Did someone tell you it would hurt the truck?

Funny story, one time I was filling up my 7.3 and this hippie lookin dude pulled up to the pump beside me in a Honda Insight. I had my straight piped 7.3 runnin on high idle in the cold, it wasn't all the way warmed up yet so she was screamin and stinkin! The guy nervously looks at me and says, you know your spark plugs can ingnite your gas fumes and you could kill us? I looked at him and said you know this is a diesel and it doesn't have spark plugs and I'm pumping diesel fuel not gasoline so I guess were good then right? He looked back and said, well............ your killing our planet! Before I could even snap back at him he had the pump back up, his cap on and taking off like I was gonna shoot him. Maybe he knew I was carrying? Oh well typical hybrid driver I guess.

Hahaha, that's hilarious man. I've got my truck running and plated now and I'm kind of hoping I get some hybrid/smug/high and mighty person telling me off just so I can rebuke. On the other hand, it could get a little ugly depending on how high and mighty they are...

I always leave mine running for my 03 7.3L, never had any issues and I have never heard of any.

In the 2.5 years Ive had my truck Ive never had someone try to start an issue with me about it, though I kinda want someone too, just so I can tell em off!

Kinda weird too, I would think with my age (20) a lot of people would wanna try and teach me a lesson

You know all the urban legend stories of static electricity sparking off gasoline. I think diesel is much more stable so I doubt you could even light it off with a spark plug, much less a zap from rubbing your shoes on the carpet.

Now in a gasoline car that monitors evap you could turn a check engine light on IF it were to test evap while you were fueling but outside of that I can't see a problem fueling a gas car. I see NO danger in fueling a diesel vehicle. Plus diesel smells better than gas, both going in and coming out.

Agreed. Most people don't know that diesel fuel isn't flamable. Unless you mix it with Tide, then it gets crazy!

The reason they say to shut the 6.0 off is because for some reason the fuel sender doesn't respond as quickly and the fuel gauge doesn't show the proper level.

I've noticed in my 6.0 that by the time I'm back in the truck, the fuel gauge is correct. Now my 7.3 took it about 10 mins of driving for the gauge to catch up, or shut it off and start back up.

Programming could have an effect on how quick it goes back. Mine is off for a little while after refueling.
