Yes, as I interpret the source info (see original post link), the goal is to prevent the intake vacuum from influencing the ICU transducer diaphragm.

Just pulling the hose off at either end would do this, but the line must be plugged so as not to cause a vacuum leak.

My method would be to remove the rubber connector from the plastic line at the ICU end, fit a plug into the plastic line, then reattach the rubber connector. You could also do it at the manifold end, but the plug might get sucked out by the vacuum.
