My lack of vacuum is the reason I'm going to manual brakes. Dave recommended I try a master with 7/8" bore. After hearing your success I'm confident I'll be happy with the swap. I also see you put in a 45 degree fitting for the hose from the intake to the water pump. I tried every hose but with my intake they never fit properly and always had a slight kink. I was always going to put in a 45 and now I see it will work
