I had to read your old link several times. I couldn't understand how the guy could adjust the pressure while driving 31 mph down the road. Finally figured it out.
Thanks for all your help. I only wish the vacuum line was shown in that picture too. I'm assuming it's somewhere close to the modulator? I quess if I find the modulator I will find the vacuum line too, I hope.
