What components are shown on this vacuum routing diagram?

It shows the fuel tank(s), carbon canister with V REST, CANP solenoid, AIR B and AIR D components with SOL V solenoid valves, EVR and EGR valve, MAP sensor, FPRC, manifold vacuum (MAN VAC) taps, throttle body, and VRESER vacuum reservoir.

Where does the EGR valve get its vacuum signal?

The EGR valve connects via the green line to the EVR (EGR vacuum regulator) solenoid shown at the bottom of the diagram.

What controls the AIR B and AIR D components?

Each is controlled by its own SOL V (solenoid valve): one labeled SOL V AIR D and one labeled SOL V AIR B, both mounted along the black vacuum manifold at the bottom of the diagram.

What is connected to manifold vacuum (MAN VAC) in this diagram?

Two MAN VAC taps are shown at the right side; the FPRC (fuel pressure regulator control) connects to a MAN VAC fitting via red lines.

How is the diagram oriented?

The bottom of the diagram is labeled FRONT OF VEHICLE.

This document is a color-coded vacuum hose routing diagram for a Ford truck emissions/vacuum system, uploaded as a 1993 49-state VECI (Vehicle Emission Control Information) schematic to a 1990 Ford Bronco gallery. The diagram shows vacuum line routing between major emissions components: the fuel tank(s) and carbon (charcoal) canister with V REST (vapor restrictor), the CANP (canister purge) solenoid, the AIR B (air bypass) and AIR D (air diverter) components with their SOL V (vacuum solenoid) valves, the EVR (EGR vacuum regulator) controlling the EGR valve, the MAP sensor, the FPRC (fuel pressure regulator control) tied to manifold vacuum (MAN VAC), the throttle body, and the VRESER (vacuum reservoir). Hoses are distinguished by color: black, red, yellow, pink/magenta, and green lines, with dashed lines indicating additional connections. Orientation is indicated by the label "FRONT OF VEHICLE" at the bottom. A reader can trace which components share vacuum sources, how the EGR, air injection (Thermactor), and evaporative emissions circuits connect, and where the vacuum reservoir and manifold vacuum taps are located. The diagram contains no text tables, part numbers, or explicit year/model callouts within the image itself.
