1986 Ford Bronco Vacuum Hose Routing Diagram - EGR, Purge, Dual Tank Lines

This document is a scanned, hand-annotated vacuum hose routing diagram titled "VACUUM HOSE ROUTING." It shows the layout of vacuum lines and emissions-control components as viewed from above, with "FRONT OF VEHICLE" marked at the bottom. Hand-written labels identify components including the A/CL DV (air cleaner duct/valve), A/CL BI MET (bi-metal sensor), ACV, PCV, EGR valve, manifold vacuum (MAN VAC) taps, exhaust heat control valve (EXH HCV), heat valve (HEAT VLV INT), TK (thermactor check), two SV CBV TVV assemblies, two carburetor canisters (CARB CAN), multiple purge control valves (PURGE CV) with a line noted "TO FUEL TANKS," distributor (DIST) vacuum connection, filter (FLTR), VCV, VDV, VRDV, IVV, LCV, HICV, VCKV, TVS, SOL V, vacuum restrictor (V REST), and AIR BPV (air bypass valve). An inset box labeled "A/C ONLY" shows additional routing (VCKV, V REST, SOL V, TK) used on air-conditioned vehicles, with connection points A and B tying the inset into the main diagram. Hoses are traced in colors (red, green, blue, tan/yellow, gray) to help distinguish circuits. A reader can use this diagram to route or verify vacuum hoses on the emissions and vacuum control system of this Ford truck, including dual fuel tank purge plumbing.
