Another AC Vacuum question
I am trying to find a good and strong source for the vacuum of my AC unit in my 72 C10 with factory air.
I need to run the hose from the vacuum tank under my dash to provide vacuum and was wondering which way would work best? I have two choices - (1) use a T and tap into the main line from the valve cover and the carb (2) use a T and tap into the vacuum advance of the distributor. What is your opinion - see two pictures below. Thanks for your help, KellerMac

Re: Another AC Vacuum question
Thanks med.bronze - does it matter which hose off the manifold that I hook to?

Re: Another AC Vacuum question
no it shouldn't, but it might be better to put a 3-port vacuum fitting on the manifold.
