You implied that every Duramax owner can prime their fuel system which is by no means accurate and most of them would see this as being a "mechanic".
No such implication was made by me, what I said was:
"IDK, the "average person" is not likely to own a HD diesel truck in the first place. There is also onstar and AAA etc to come help out."
I also never said anything such as "Duramax owner can prime their fuel system"
or that any percentage of diesel owners are in any way a mechanic. Those were all embelished extrapolations you created on your own.
To me, the average motorist I was refering to drives a gasoline powered vehicle such as sedans, minivans, light duty trucks, etc. I would bet that a higher percentage of diesel owners are a lot more aware of their vehicle's operational needs than the average gas owner. Sure, there are a lot of people who buy diesels who simply use them for grocery getters or posing (compensating?) but most people who shell out the extra $10k+ for a diesel/Allison are far from the average motorist.
Further, priming a current diesel is pretty much a no-brainer for anyone who can check their own oil, tires, trans fluid, tie their own shoes, etc. (my Ford van didn't require any technique after running out of diesel other than add more diesel and crank away. Worked fine for me the 2 times I ran out in that vehicle) The method described in my LML manual appears to be about the simplest thing a person can possible do with a basic tool. It would only be easier if the method involved hitting something with a roadside rock. Additionaly, my GMC came with 2 batteries which should allow for quite a lot of cranking.
