Hello members, I am a proud new owner of a 1966 Pontiac grand prix. 4 barrel carb with a/c and p/s. I am looking for a vacuum hose diagram for this vehicle.
I have searched the web with no luck. Any thoughts?
correct. engine was disassembled for reconditioning and im stuck trying to figure out this puzzle.
there are 2 vacuum sources coming from intake manifold. one is on the lower runner and one on the upper runner. both appear to be connected to a plastic 3 way tee and other nipple of the 3 way goes to pcv valve. strange to think they have 2 vacuum sources for pcv system.
thank you sir for the information. I went ahead and took your advice and ordered myself a service manual. I am not very familiar with the Pontiac product but am learning so much about this project I inherited. the service manual will be handy.
