Vacuum Unit Connections
Vacuum control valves are connected differently on the various engines. Refer to the Vacuum Diagrams shown below and on the following pages for connections for each engine with or without these special controls.
NOTE:
Additional vacuum lines are also used for other controls, such as Vacuum Override (Thermostatic Air Cleaner control) and By-Pass Valve (Air Injection Control on Thermactor Engines), and these lines are also shown on the vacuum diagrams.
