Hope that this is not a really dumb question. I understand that the idea is to prevent air from entering the fuel system and reaching the injectors to quiet down the engine/cackle. Other than the noise, is it detrimental to the injectors and engine longevity when this happens? And if so, why would Ford have designed the fuel return system in a way that would cause this situation?

Yes, air introduced into the injection system is bad. It is bad for the pump and for the injectors. Imagine if you were hiccuping for hours on end. Thats kinda what its like for your engine.
Just remember that any given car/truck is a compromise of the best technology at the time vs cost to build/sell. I would love to have been able to own one of these new and really know how they ran and sounded. Probably great, but car makers don't really build them to last 100-300k,and more, without maintenance. And upgrades.
Thanks for the response guys,
As treckbasso pointed out, as this is my first powerstroke I have no idea if I actually have a problem with air or not. I also have a '98 MB E300 TD and it "rattles" some but it is not NEAR the size or type of engine the 7.3 is, so it is not much to compare to.
