Can someone tell me if there's a GOOD complete vacuum hose diagram available for the '72 1.7? Besides Pelican site, Haynes & Drake manuals please.. They all leave out some of the hoses and are incomplete for my model. The Porsche shop manual any better? Somebody draw up a good one?

#10 is the Decel Valve. It opens when there is very high vacuum in the manifold, to allow air to bypass the throttle body.
The "additional air regulator" is what we usually call the AAR. It allows air to bypass the throttle body when the engine is cold, and closes off as the engine warms up blocking that extra flow. The AAR is part #5 in that same diagram. --DD |
