does anyone know what this hose does/go to? I will attach the image and I found it when I was moving my bed off a little. it sits right next to the differential on top. Thanks.

There is a hole in it. Not leaking or anything. just wondering if its important to change if not, I'll leave it. its hard to research online because I don't know what its called or what its hooked up to.

 

It's part of the EVAP system, just wrap some duct tape(or electric tape) around it, it will set a code over time if hole is not sealed

There is gasoline fumes in that hose while driving

Round tank is the charcoal canister
Rectangle box is fuel over flow container,can't remember its exact name but its there for people who over fill their gas tanks, the extra fuel will sit in that box and evaporate instead of going into charcoal canister and ruining it

 

Vapor canister.
