Purge valve for the evap canister. Shorten the hoses to it so it's not hanging out so far.

Yup, purge control valve...

Being in CA, you'll need to keep it in good working condition. Looks like one of the hose nipples is already broke off of it. Time for a new one, with the hoses of appropriate length as well.
