I had removed my intake manifold for my '63 SDV 390. There is a tube inside it that puts heat up to the choke via an aluminum tube. The other end is to protrude out from the bottom side of the intake manifold to get fresh air. Where is this other end supposed to go? Mine is snapped off. I will be replacing the tube and want to know where to route it to. My guess is it may come from underneath the carb on the driver's side via a vacuum hose?
Andy, the tube is stainless steel. The tube runs from both sides of the intake. On the right side, about in the middle of the carb mount base, you will see a hole for a metal tube to fit into. The other end on the left side of the intake is the inlet, and is viewed from the bottom of the intake.
