If this is a hard plastic line which is what it looks like, it is more than likely this is for the washer fluid. There are a couple connection points for this line so it may have just come off. If not, then it broke and needs to be replaced.
I am attaching the info for this line as it is going to connect to the nozzles under the hood and then the pump as well that is on the bottom of the reservoir.
Please see the attached info and let us know what you find with this.
Thanks
