My 2000 S has an vacuum leak in a line leaving the left front of the manifold at the point where number 23 is shown in this diagram. The hose goes left and down under the car heading forward. I'm almost positive it's the vacuum feed for the brake booster.
The online parts places and Porsche catalog show the following diagram. Is number 14 below the right part? My line is leaking at the accordian section at the top where it has rubbed on the chassis. It looks like this line has a junction under the car.
Can anybody confirm if I'm on the right track here? I'm getting ready to order part 14. If anybody has performed this repair and has any insight I'm all ears.
