Ggarvis,
Sounds like you are making good headway, I hope I will do the same as soon as I can get my supply line replaced and set about working down the vac lines to each system. Keep us all posted on your progress as I would hope to learn from what you discover.

Just a thought about the brake booster. what is the pedal supposed to feel like? I am not sure if it is the age of this car or if the brake pedal actually feels a little hard. I put my vac hand pump on there and after a great deal of pumping was able to get it to register that it was holding vac. I was thinking that if the booster was not holding vac then it would not matter what was connected to the nippples on that supply line. Is my logic correct? or am I over thinking this.
