What is this?

I have a part on my truck I need to replace, I can’t find anything online that looks just like it so it’s hard to tell. But I believe it’s a rear proportioning valve. New to working on my truck so I just want to make sure I get the right thing.

That’s on the rear axle correct?

Axle vent hose with the side to side brake fitting in it?

Sorry guys I just checked this. But yeah it’s on the rear axle, I appreciate the help

As mentioned. That is a brake line. With the axle vent. I just replaced this on my 03 2500. Got it at advanced auto.
