Vaccuum line?

What is this line?
In the photo it is the one I'm pointing to.

What year? It looks like a vacuum line for a fuel pressure regulator.

Yep, my bet is what I said.

Where can I buy it?

My bet would be a dealer. Might have to source a used one if no longer available. A short line like that you could replace with a piece of rubber line.
