Hello from paris France,
would like to learn about air lines and vaccum on my 914 2.0 GA 1974. I do not understand why the oil vaccum breather is pluged after the buterfly with a dizzy line and the valve for deceleration additional air. Thanks for your help CheeRS |

The number 10 hose is only there to keep crap out of the vacuum canister.
The distributor only uses the vacuum retard (hose 11), so the hose 10 is attached to the vacuum canister but the other end of the hose is just tucked under the intake plenum and not connected to anything. As the vacuum retard moves the diaphragm in the vacuum canister, air has to be able to go in and out of the advance side of the vacuum canister. Jim |
