The system is designed for blowby to go through the CDR valve and from there into the intake air stream so you really can't tell how much blowby you have unless you block off the CDR valve. After doing that, the only way for an accurate check is with a manometer and the spec is no more than 6" at governed no load RPM. The CDR is similar to a PCV in a gas engine only unmetered and way more blowby flow.
Lift pump pressure is fairly low, something like 3-5 PSI. Not critical to IP life like I understand it is on the Cummins.
No set time on the drainback hoses and O-rings, if you don't see a visible fuel leak, they let you know by extra long cranking time in the morning after sitting overnight. Local injection shops still carry fuel system components.
As far as the E4OD, I've personally known people who treated there's like gold, towed very lightly if at all, and yet their's failed. Others have had no problems. Nowadays I understand there's updated parts so when overhauled they're better than new.
