What model year does this vacuum routing decal apply to?

The EPA compliance text on the label states it is applicable to 1985 model year trucks.

What spark plug gap is specified on this decal?

The label shows GAP-.042-.046 (inches).

What emissions components are shown in the vacuum hose routing diagram?

A/CL DV, A/CL BI MET, ACV, PCV, EGR, two SV-CBV TVV valves, MAN VAC taps, EXH HCV, C/O HCV, VCK V check valves, V REST restrictors, fuel tank lines, SOL V solenoids, PURGE CV valves, VCV valves with FLTR filters, VCS, DIST (distributor), and AIR BPV.

Does the diagram show any air conditioning-specific vacuum lines?

Yes, one hose section at the lower right of the diagram is labeled "A/C ONLY."

AI caption July 2010 · Photo 7 of 19

This document is a photograph of a factory under-hood emissions/vacuum hose routing decal, site-classified as belonging to a 1985 Ford Bronco. The right portion shows the complete "VACUUM HOSE ROUTING" schematic, depicting hose connections among emissions components including the A/CL DV (air cleaner duct valve), A/CL BI MET (bi-metal sensor), ACV, PCV, EGR valve, two SV-CBV TVV (thermal vacuum valves), manifold vacuum taps (MAN VAC), exhaust heat control valve (EXH HCV), C/O HCV, vacuum check valves (VCK V), vacuum restrictors (V REST), two fuel tank connections, two solenoid valves (SOL V), purge control valves (PURGE CV), vacuum control valves (VCV) with filters (FLTR), VCS, distributor (DIST), and the AIR BPV. Hose colors (red, tan/yellow, green, black, dashed) are printed on the label. Orientation is marked "FRONT OF VEHICLE" and one branch is labeled "A/C ONLY." The partially cropped left column contains tune-up/adjustment instructions (references to 575 RPM, 700 RPM idle-set procedure, throttle screw), a spark plug gap specification of .042-.046, and an EPA compliance statement stating applicability to 1985 model year trucks, confirming the year. Useful for restoring correct vacuum line routing on a 1985 Ford truck/Bronco.
