The valve priming station () has a boot (), a vacuum chamber (), and a vacuum channel () in the boot (). The vacuum channel () connects with the vacuum source () via the vacuum chamber (). The boot () sealingly engages a valve nozzle () of the fluid dispensing valve () so that the vacuum chamber () connects the vacuum source () with the fluid chamber (). The vacuum switch () couples with the vacuum channel () via the vacuum chamber () and has an opened and closed position based upon a vacuum level in the vacuum chamber (). The controller () is electrically connected with the vacuum source () and vacuum switch () and controls priming of the fluid dispensing valve () based upon whether the vacuum switch () is opened or closed.
