Reply to "Diameter of vacuum booster tube inder the car"

panteradougMember

3/8 is probably ok. It's just for the brakes.
I used 5/8" od ss tube and -10 Russell ss hose.
I believe that the factory banjo on the booster is for 5/8 hose (inside diameter).
By process of elimination the intake fitting must be for 5/8" hose also.
Since I never had the original intake manifold on this car, it was an Edelbrock when I first got it, and it has Webers on it now. I don't know what the original factory connection looked like.
