I'm actually not looking to hook anything up, I'm just trying to follow the vacuum diagram printed under the hood to find where there should and shouldn't be hoses. Someone "redesigned" the vacuum system in this truck, and I was having trouble identifying what components went where. I think it is correct now as the motor is running smoother than ever before, then again it may be the new head gasket, exhaust gasket, belts, water pump, valve train, carburetor rebuild, and ignition solenoid I have installed in the last few days.
