1985 Ford Bronco Vacuum Hose Routing Diagram - EGR, TAB/TAD Solenoids, Canister

This document is a photograph of a factory underhood vacuum hose routing diagram (emissions decal/reference sheet) for a carbureted Ford vehicle, uploaded to the gallery of a 1985 Ford Bronco. The schematic is oriented with 'FRONT OF VEHICLE' marked on the left and is titled 'VACUUM HOSE ROUTING' along the right edge. It depicts vacuum line routing for both single-tank and dual-tank fuel configurations, with fuel tank vapor lines feeding carbon canister(s). Components shown include the MAP sensor, air cleaner duct/diverter valve (A/CL DV), vacuum retard delay valve (VRDV), air cleaner bi-metal sensor (A/CL BI MET), air pump and air control valve (ACV) routing to the catalyst (CAT) and engine (ENG), intake manifold (INT MAN), carburetor with EGR valve, P/D motor, TVV and SV-CBV valves, vacuum check valve (V CK V), CPRV, PCV, and three solenoid valves (SOL V) that control the EGR, TAD (thermactor air diverter), and TAB (thermactor air bypass) functions. Hoses are drawn with different line styles and colors (orange, green, black, pink) to distinguish circuits. A reader can use this diagram to identify how each vacuum hose should be routed between emissions components when reassembling or diagnosing the vacuum system.
