Diesel Bombers - FNG checking in

Hi folks!
I've been lurking here for a while now, picking up tid bits of information, but I didn't have a diesel vehicle to learn any specifics. Well, that all changed last payday! I was able to latch onto '92 F-350 7.3 idi with 187,000 original miles on it. It comes with a Banks Sidewinder kit installed.
It's been reasonably well maintained (mostly complete service records came with it) but does have a few things going on with it that I'd like to address, in the proper forum of course.
Thanks for reading!
