1986 Cabriolet hose diagrams
 

I have rebuilt the 3.2L engine in my 1986 911 Cabriolet. The engine is in the car and I am up to hooking up the emission and vacuum hoses. There are a couple hoses I can not see where they go, the large vacuum hose for the speed control and another hose, 3/8 diameter about 15 inches long with a few molded bends which is open on both ends. I cannot find a diagram for hose routing in the Bently service manual or the engine rebuild books. Is there anywhere I could get a diagram showing the hose routing?

Thanks

The engine lid should have the Vehicle Emission Control Information label. This is from my 87.

The following 86 PET Illustrations have the vacuum line routing.
107-00 L-Jetronic I
107-05 L-Jetronic II
107-10 L-Jetronic III
907-00 Cruise Control

For the cruise (speed) control, I believe the large hose vents to atmosphere and the smaller one connects to a "T" by the brake vacuum booster line. See Cruise Control Vacuum Line.

I think the other hose you are describing is 930-207-236-00 item 28 on Illustration 107-00. It runs between the throttle body and air valve.
