What spark plug gap is listed on this emissions decal?

The decal lists a gap of .042–.046.

What components are shown in the vacuum hose routing diagram?

The diagram shows the ACV with ENG and CAT ports, MAP sensor, FPR (fuel pressure regulator), fuel tank(s) line, carbon canister, manifold vacuum (MAN VAC) tee, TAB and TAD solenoid valves (SOL V), EGR valve, EVR, throttle body, and a PRV.

How are the vacuum hoses identified in the diagram?

Hoses are color-coded in the diagram — red, yellow, pink, green, teal/blue, and black lines route between the components.

Does the decal indicate a model year?

The partially cropped compliance text reads '...92 model year new...', indicating the label references 1992 model year regulations.

Underhood emissions decal showing color-coded vacuum hose routing to throttle body, EGR, MAP and carbon canister.

AI caption April 2013 · Photo 4 of 16

This is a photograph of a factory under-hood emissions/vacuum hose routing decal, site-filed under a 1995 Ford Bronco. The main portion shows a 'VACUUM HOSE ROUTING' schematic with color-coded hoses (red, yellow, pink, green, teal, black) connecting the following labeled components: ENG and CAT ports on the ACV (air control valve), the MAP sensor, FPR (fuel pressure regulator), fuel tank(s) line, carbon canister (CARBON CAN), a manifold vacuum (MAN VAC) tee fitting, TAB and TAD vacuum solenoids (each marked SOL V), the EGR valve and EVR (EGR vacuum regulator), the throttle body, and a PRV at the bottom edge. The left side shows a partially cropped emission tune-up information block mentioning idle speed/idle mixture, engine operating conditions (accessories off), reference to a shop manual, a compliance statement referencing '...92 model year new...' vehicles, and a spark plug gap specification of .042–.046. The decal is useful for verifying correct vacuum line routing and colors between the emissions solenoids, EGR system, evaporative canister, and fuel pressure regulator on this Ford EFI engine.

This document covers 1992, which may differ from this 1995 Ford Bronco.
