Vacuum Issues e99

i am trying to diagnose a vacuums issue, and i was starting with the motor, am i correct that if i plug line by line i should see which one doesn't hold pressure, so i started at the pump and after plugging the line coming off the pump i thought the pump would shut off after it built pressure and it didn't so i would venture to guess there pump is no good and replace it and start form there, what do y'all think.

thanks,
-will
