Chrysler Vacuum Hose Routing Diagram Decal 4179622 - Carbureted V8 ESA

This document is an under-hood emissions/vacuum hose routing decal, part number 4179622, produced by Chrysler Corporation and photographed affixed to an inner fender/firewall area. Titled "VACUUM HOSE ROUTING DIAGRAM," it depicts a carbureted V8 engine with color-coded vacuum hoses (black, red, yellow, orange, blue, green) and identifies key emission-control components and their hose connections. Labeled items include the carburetor bowl vent hose, canister purge hose, canister signal hose, vacuum amplifier, vacuum solenoid valve, filtered air bleed, a hose connecting to the power heat valve (steel) vacuum tube, the line to the fuel tank, dual vapor canisters, CCEV valve, air switching diverter valve, EGR valve, PCV valve, and the manifold vacuum source. An inset "AIR CLEANER – AUXILIARY VIEW" shows the temperature sensor, ESA (Electronic Spark Advance) module, ESA vacuum transducer, ESA vacuum hose, heated air vacuum diaphragm, and the air cleaner heated air door hose. An engine designation field at the top right is illegible. A reader can use this decal to verify correct factory vacuum hose routing and identify the location and connections of the emissions components on this Chrysler-built carbureted engine.
