Vacuum line on xfer case

[Tex06]

What is this black rubber line on the transfer case? NP231 off a '92 MJ w/4x4.

 

I cut it, will reconnect if important when installing new tranny.

Breather vent line.

Yup, vent line, it is important.

Vent. You need it.

I extended mine by using a piece of hard brake line as a joiner to add more tubing.

Yep figured that out once I got the tranny out. I'll run it up into the engine bay like the front axle
