Identify where this goes

[Sir Bonksalot]

Hey, I was tinkering with an unrelated problem with this car but I noticed this. I know it’s the 4x4 locking hubs line but for the life of me I cannot figure out where it connects. It appears broken but I can’t find the other side. Thx.

Kinda looks like the vent. I'll check mine.

Should be your front axle vent tube. Just zip tie it secure to the brake line there. You just don't want it to get submerged in water if you go through a deep puddle or something. You can follow it down to the other end and it should be attached to a nipple on the front axle.
