Hello ! I have mounted a Inglese intake manifold with 4x48 Weber carbs. It looks nice, but there is no vacum in this manifold for my brakes. I consider mounting a electric vacum-pump. I was told that there are alternators with built in vacum-pumps, does anyone know where to get one ? Are there any good electric vacum-pumps anyone can recommend ? Grateful for all answers !
