Rocky,
Truth be known, I was more curious about the "hydraulic system" marking tape that is on what looks to be a formed section of -6 CRES tubing that comes off the inlet manifold behind the middle carburetor. The tube stock and bending tools are easy enough to come by, but having that marking tape is unusual. Where did you round that marking tape? It also looks like you are using some of the blue fabric covered Aeroquip (or similar) hose to finish up the vacuum run to the servo. I used that "blue hose" to hook up my oil separator and PCV valve as well as the brake servo.
As for the silicone hoses, the short, upper hose comes off the heater valve location, easy enough to figure out. Given that I was operating under the assumption that the other silicon ran to the heater core from the water pump housing. I have to ask, how is the heater core tied into the rest of the cooling system on your car?
