67 a/c heater vaccum routing
I need some help on the vaccum hose routing for a 67 sb with factory air. I know it goes from the manifold vaccum to the a/c heater switch on the a/c heater box, out of the a/c heater switch to the heater control valve. I'm just not sure about the in and out side of the a/c heater vaccum switch and the assembly manual is not very clear on this. Thanks.

The search function is your friend. Also the FAQ Section at the beginning of this C2 Forum page.
Here is one from our archives that may help: https://www.corvetteforum.com/forums...y-a-c-car.html
I believe this vacuum switch has two different size ports to go along with the two different size vacuum hoses. Just match the hose size with the fitting.
