What purpose do the vacuum ports serve? Could I convert another WUR from a another application, make it adjustable and use that?

I couldn't help myself I opened up the 930 CPR aka "wur" and wow was it corroded. Look at the pin.

I sourced this other WUR from a Jetta. It looks brand new inside, but does not have vacuum ports. I put it on and it seems to work okay. Pressures are different of course. 74psi for control pressure, cold pressure 72, Warm seems to climb up to 72 also from about 64.
