You could run what you want to fit. I had spare unused bits too. I just used what was needed minimally in order to connect it. My gauge supply is tapped into my vacuum for my AWE DV, so set-ups vary and I think they give more than what you really need.
Mine has a 1/8" to 3/16" coupler(in the green circle) and the red arrow point to my splice into my DV vacuum source. If you need any vac line connectors look at NAPA.
