A rat got into my 2011 E250 and chewed the vacuum line from the intake and some front right head light wiring.

See below video. They made another video about this particular van and mentioned its 2013 I think? But the whole setup looks like my 2011, including under the glove box. All I had left under the hood was the hose going to the intake. The vacuum reservoir looks hard to get to without removing the AC dryer and a bunch of other crap.
If the video below is correct, I need some tubing, a T, a check valve, a new reservoir, and a way to couple onto the black poly tubing going to the damper controls (behind the glove box. In the video the guy tugs on it and it comes from the firewall going up). Problem with the video, is it is just crappy music and no explanation. Do I seem to have a good handle on this hack repair?
