This months Trailer Life Magazine had a write up on the 5.9 Cummins engine, the write up covered at least 6 or 7 pages. As I read the article all 5.9 Cummins engine block coolant plugs rust out. T...

OK Troy, whatever you say. We all know you take every opportunity to say the Cummins diesel is junk. That's fine. Pretty sure that opinion is contrary to most people's opinions and experiences.
But hey, we are all allowed to have our opinions. :)
Carry on...:B
OK Ian... I've owned 05 Dodge and my cousin wrenches on them. Injectors on these common rails fail more than your internet buddies report. :W
People with the 03-07 5.9 Cummins should be running as small of a micron fuel filter as possible if they want to make it past 150K.
Say bull all you want but you talk to Dynomite Diesel or any Bosch injector shop and they will tell you the same.
Like everything there are variables. So you won't run a 4 micron filter if it will help your injectors run longer?
There are several things one can help prevent or fix on a Cummins if they so choose.
1. replace starter contacts before it won't disengage and burn up wiring
2. replace lift pump on 98-02 24 valve before the lift pump takes out the injection pump.
3. Tab killer dowel pin before it comes out and damages the timing case.
There are several more but bury your head and roll the dice. I don't I fix things before they become a problem.
4. Delete (At your own risk) all the emissions******(ie DPF/EGR). Every hot shot truck I see has some how lost the DPF. :h
I believe improved fuel filtration can only help, but not limited to. I'm not sure what are the tolerances of the parts inside a injector, but I bet they're much tighter than engine parts. Add in minimal lubrication from ULSD, Pilot injection (cycles your injectors 5X compared non Pilot injection engines) and a fuel filter that passes some solids to your injectors so injectors do fail for various reason.
