Vacuum Hose Drawing

EF & EC-204component photo

GA16DE engine.

Vacuum hose routing drawing for the GA16DE intake manifold. The upper view shows the intake manifold collector with the throttle chamber at the right end, a vacuum gallery line running along the top of the manifold runners, and a pressure regulator at the left connected by a vacuum hose. A 'View A' arrow points to the throttle chamber/collector junction area. The lower 'View A' detail shows the throttle chamber elbow with vacuum hoses routed to the pressure regulator.
