AI caption October 2010 · Photo 94 of 653

This is a photograph of a factory Chrysler Corporation vacuum hose routing diagram decal, part number 4405730, applied to a metal panel (apparently under the hood or on a body panel of the vehicle). The label is marked "ENGINE 5.9L-4," indicating it applies to the 5.9L (360 cubic inch) carbureted V8 engine. The schematic shows the routing of vacuum hoses among emissions and engine-control components, including the carburetor, EGR valve and EGR amplifier, PHV/EGR solenoid, air switch relief valve (ASRV) solenoid, heated air temperature sensor, heated air diaphragm, PCV valve, power heat valve (PHV), trap door and trap door delay valve, spark delay valve, T.I.D.C. valve, air pump with upstream and downstream air switching, vapor canisters, thermal and electric bowl vent valves, CVSSP, and connections to the fuel tank, air cleaner, cruise control, and heater/A-C control. A dashed-line legend indicates optional vacuum-operated accessories. Partially visible to the left is another decal showing tool storage and jacking/drive information ("REAR WHEEL DRIVE"). A reader can use this document to identify correct factory vacuum line routing and component names for this Chrysler/Dodge 5.9L application.
