Tried the search button but no luck, here is a pic of the difference between the PCV hoses on Earlie and later model rangers =
Small tube is 19-21 ranger # lb5z-6a664-b
Big tube is 21-23 ranger # lb5z-6a664-e

It is the tube that connects the intake vacuum port to the pcv valve, just wanted to show the difference between the early and later model design

Is the bigger part of the big tube just a covering? Or is that the actual tube?
I would have to see how it is routed on the engine, but maybe the smaller tube had clearance issues and a potential for wearing thru. The big hose seems to be molded to avoid obstacles, and the sleeve over it to prevent wear.

He is referencing the design change, that moved the vacuum intake port upstream to here.
Newer design - moved the Vacuum Port - Upstream
So, the need for a longer tube, feeds down to the Crankcase Vent Oil Seperator, pic below.

From Here:
The open end of the tube, connects to the Intake Port (blue connector)
Older Style (Design) had the port lower.
