'87 F250 4V 460.
Is the vacuum motor in the scoop on the *drivers side* of this housing replaceable?
It lets engine compartment air into the housing @ WOT and should be closed @ cruise.
I've been chasing vacuum leaks, and this diaphram is shot.
The line is plugged for now but it FAILS open, so there's always cold air flowing and the heated air riser @ the snorkle is not as effective as it could be.
Looking at it I don't see a seperate p/n and am thinking there's no way to service it short of buying a new housing......Yeah, right...

Anyone on here know about these things? TIA any advice.

You may want to try the research department at Green Sales at 513-731-3304. Just provide them with all the information and they may be able to help you.

 

My '86 has the same fresh air rig on the air-cleaner housing and yes, it's blown too.
