The inlet manifold wants to be able to suck air out of the servo so install so you can blow into the manifold.

The servo is vacuum assisted i.e. air is drawn out of the servo by the depression in the inlet manifold and a vacuum is held in the servo by the non return valve whilst on boost. When fitted you should be able to suck air out of the servo, but not blow air into it
