So I confirmed that the hose is definitely running from the water pump to the vacuum storage tank. The tube on the driver side of the engine block is open and after looking at the pic (included) is blocked and both my heater cores have no hoses connected at all. If anyone has a diagram of how all this is supposed to be hooked up the right way, I would love it so I can get all this right. When I had my 69 GTO as a kid, with no extra money, I assumed that we did anything we could to make it run. It seems like that was the plan for this car.

Thanks again
