So while repairing a coolant issue I found that my vacuum line from my resonator to my fuel pressure regulator was broken. It broke right where the line enters into the rubber elbow.

I have read that having this little line broken will cause your vehicle to idle rough or not properly. I have noticed before my coolant issue that my vehicle would have some rough idling from time to time.

Does anyone have any advice on how to repair this? Do I have to make my own vacuum line hose? I seem to can't find the part online at all.
