I just purchased this car and notice a "noise" - we discovered a hose was not attached and upon further inspection it appears that someone had glued it where it was broken

Can anyone tell me what this is called? I don't have any problem changing stuff out myself but am having a hard time figuring out what this is.
The photos are pretty self explanatory of what I am trying to find out - but in case it is not
Can I just replace the hose?
If not, what is the piece called that it attaches to?

 

I have the same issues what wire is it called I broke mine changing the spark plugs now I'm scared to start the SUV....2007 Equinix

 

has anyone figured this out?

 

That hose attaches to the EVAP system purge valve - also called the charcoal canister or canister purge valve.

If it’s the valve that’s broken, the nipple can be removed from the fitting by pressing the white tab on the fitting and using needle nose pliers to pull it out. You may need a little spray lube to work it out. The valve will have to be replaced.

If it’s the plastic hose that’s broken (or if the nipple can’t be removed), it can be spliced or replaced using 1/4” or 5/16” emissions hose and clamps, available off the shelf at any auto parts store. If you don’t want it spliced, the line assembly from the purge valve to the steel line on the firewall should be available from a GM dealer. It will require a heat gun for installation.
