From Peter Davis:

Could anyone tell me what the maximum vacuum pressure is for the Perkins. I can't find it in the Oka or Perkins manuals. I have a gauge which is 25" H2O restriction.

From Peter & Sandra James Oka 374:

I've not been able to find any data in the manuals I have but asked a diesel mechanic and he just said if the gauge is showing any reading then the aircleaner is restricting airflow. I suspect he was talking about the standard type of Donaldson restriction indicator that is normally fitted rather than an analogue gauge.
