Like I said:
Motocraft numbers (for RockAuto):
PCV valve: EV-261 (2C5Z-6A666-AA)
Hose to Throttle-body: KCV-240 (2L2Z-6A664-FA)
There appears to be no MGR number for the PCV valve even though it is "replace" at 90k on the service schedule!
Not sure about the hose.
If you need to identify WHERE the thing is and/or what it does, please PM me.
