Almost done changing my intake gaskets and decided to replace the heater hose from the intake and check to make sure the restrictor was in there. To my surprise, no restrictor! So I bought one from Ford. The plastic one with the rubber doughnut for restriction. Part number XR3Z18599AA.
Scoured the net to find out install location and got various answers. I know the restrictor has to go in the inlet hose (one from the intake). But which end? Put it right next to the core or right at the intake? Putting it at the core would make the rubber hose absorb all that pressure which could lead to it popping?
