Yep you got it. Really that is a thing of the past too.

I've let tractors idles for hours upon hours before... The main thing you have worry about is the oil press which came be compensated by bumpin the throttle up to 1000r's.

 

If your running diesel injests those gasoline fumes through the air intake you may have what is known as a run away diesel with no way to shut it off. Again slim chance, but there is a chance.
I don't now anyone thats been injured by running with scissors either but that doesn't mean its a good idea.

 

Orig.. there was a thread somewhere about that a couple months ago. I guess it did really happen to somebody that was filling up at one of those stations that have the diesel and gas pumps on the same island.

Side note.. back in the day we used to dip a rag in gasoline and wrap it around the air cleaner of an allis when we didnt' have ether around. Worked great.

 

Ok that makes sense. And low oil pressure is bad b/c the ejectors rely on oil pressure to work, but when you boost RPM's it speeds up the oil pump and makes it ok. Sweet thanks again FARM69

Yeah, but I knew a girl who poked her eye out running with a pencil

 

Thats it, leaving your diesel truck running while filling up at a service station is like running with a pencil.

 

i personally have had trouble with starter solenoids so I know that they can and will deteriorate and cause starting problems, so, yeah, I keep my diesel running during fillup. basically any time i can realistically avoid shutting down i will, just so i won't have to replace starter solenoids. seriously, the ignition process and wear-and-tear on those mechanical parts isn't worth a teeny-tiny bit of safety at the pump, imho.

 

I run with pencils and scissors as well...One time I ran around my truck with a pencil in one hand, scissors in the other while I was filling up with the truck running...I just like living life dangerously...

You should really consider using glass containers for your gas. I wouldn't want anyone to accuse you of slacking.

 

anybody considered one of these? I know they use 'em in tractor pulls and stuff. Seems like a 100% effective way to stop 'dieseling' if it starts running of fumes in the air.

Yeah, I've seen them before on a couple pullers that I've looked at. Wish they would have put those on them old Detroits. I bet it works much better than wrapping your jacket or shirt around the air cleaner.

 

You are Johnny Dangerously, but you didn't share your chosen attire for the event.... loin cloth, birthday suit, or??

Oh yeah, the OT, I shut it down when filling up.

 

I never shut down when filling up. There is just something about hearing that powerstroke idle. For some reason I just love the sound.

Also if it takes you in between 3 and 7 minutes to fill up you will burn less fuel then if you were to shut her down and start her up.

But for me it has nothing to do with the fuel savings....It's all about listening to that beautiful music coming from the "stroke".

 

Hummmm a run away diesel.....running off the gas vapors from the guy fueling up his gasser next to you........yea......ya see that often? I doubt it. Thats as good as saying I don't want to shut it down because it will wear the starter out to keep starting the truck. Thats what I tell my wife.......she buys it.

I leave mine running in the winter. Because the folks riding with me want the heat on.

 

I was taught (on a farm with only diesel equipment) to never shut the machine or truck off if you can avoid it because:
- The engine may not start (not as likely with a PSD Ford than a Hough 70 payloader, but still)
- If it has a turbo you will deprive it of oil when stopping it and starting it
- If it has a turbo and you've just been working it you have to cool it down before stopping the engine
- The engine doesn't have good lubrication when starting it until it's running for a few seconds, this can accelerate wear in the top end.

I was also taught by the same people the following about leaving it running:
- An old motor may have bad oil pressure when idling and hot
- A big, old diesel may actually cool off and need to be warmed up again if you let it idle in the cold for too long and don't have the radiator blocked with something (or the shutter closed if they work)
- If it has a hydraulic system and it leaks, you will loose more hydraulic oil idling it than shutting it off.

So what do I do? I leave it running when filling it up or idling it for a short while but I only ever fill up a diesel only stations (truckers and old Mercedes Benzes only and everyone leaves theirs running).

About the engine running away on fumes, yes it can happen (though unlikely) and it can happen if it springs an oil leak into the air intake (turbo/supercharger seal kicks it, etc). Old Detroit diesels are prone to this (bad S/C seals) and yes FARM69, some did come with air intake cut-offs (all of the two-stroke Detroits I have owned or operated had them, though many were not hooked up in a place where you could use it without getting out of the cab!) What I love about diesels (aside from the sound and smell) is also their liability: it only needs fuel and compression to run, so if you are giving it fuel from somewhere and it's getting air for compression it will run!

 

Cheven, I never knew they had cut-offs. Used to work for a company that had an old one that every once in a while did that. The thing was in really rough shape. I doubt the cut-off worked anyhow. Sure did get the heart pumping when it did it though.
