Fix it. That is your EVAP canister purge solenoid hose from the canister to the solenoid. It will trip a CEL.

And will also cause a vacuum leak, resulting in a lean condition and poor idle.

go to the auto parts store and get a piece of vacumn tubing and reconnect, so it looks like the one next to it.. maybe even replace the tubing on both of them

Most of the cars have a vacuum diagram on the radiator support and while it'* not the clearest, it should assist you in determining where a line should go if one were missing.
