What is the function of this hose?

Hey folks!

Can anyone tell me what this small hose coming out the back of the air intake is?

Mine is obviously broken. I'm wondering if this is something I can take on myself? Can I just use generic hose or will I need something specific? (I'm reasonably handy, but definitely not a mechanic.)

Thanks!!

 

That normally goes over to your evap canister which appears to be missing?

Follow it to the other side, replace it with generic vacuum hose from a parts store, or just pull some slack over and reattach it

 

Just cut a nib off the tip and slip it in where the previous place tore off. The hose itself has enough slack to be pulled over.

 

2003.5 & 04 have the canister under the bed.

@OP just order some vacuum tube online in various sizes and replace all the vacuum lines you can your hands on. If that one is broken, the others are due.

 

My intake has a plug on that port. What's up with that? Can someone show how this connects to the evap? I thought it was if I wanted to connect a supercharger. I've got all those holders along the way that indicate that there should or could be a hose there.
