Nope, you can't flood a diesel, unless you have real bad injectors.
The next time you swap a filter, pre-fill the new filter before screwing it on; THEN,
don't mess with anything else; leave that Schraeder-valve and the injector lines ALONE; just fire it up.
What happens when you go to messing with "bleeding" the Schraeder and such is the pump then sucks in all that air and it won't start.
If it started fine before a filter swap and you only swap the filter with a PRE-FILLED filter, and
didn't mess with anything else, the engine will never know the difference and will fire right off.
In all the years I ran my old 6.9 (over half-a-million miles), I never resorted to "cracking" an injector-line and the cap was never removed from the Schraeder.
