Vacuum routing diagram for a 5.0L engine showing color-coded hose runs to the EGR, FPRC, vapor management valve, and solenoid valves.
Part of 1992-1996 Ford Bronco Vacuum Routing Diagrams
This document is a vacuum hose routing diagram for a 5.0L (302 cubic inch) V8 engine, uploaded to a 1992 Ford Bronco gallery. The diagram traces vacuum line routing among emissions and fuel system components. It shows the Vapor Management Valve (with a tan hose) connected toward the fuel tanks and the carbon canister (carbon can). The throttle body feeds the EGR (Exhaust Gas Recirculation) valve via a green line. A manifold vacuum source (red lines) supplies the Fuel Pressure Regulator Control (FPRC) and a line marked 'to vacuum check valve.' Black hoses run to and from the vacuum reservoir. Three solenoid valves are shown along the bottom: the EGR solenoid (green line), the AIR D solenoid (yellow line, noted as '49 states only'), and the AIR B solenoid (pink line), which control the AIR B/AIR D air-injection diverter assembly. Lines also route to the engine and the catalytic converter. Hose colors labeled include tan, black, red, green, yellow, and pink. A reader can use this diagram to identify correct vacuum hose routing and color coding for emissions components (EGR, air injection, fuel pressure regulator control, and evaporative system) on this 5.0L application.

Frequently asked questions
- What color is the vacuum hose from the throttle body/EGR circuit?
- The line from the EGR at the throttle body is labeled GREEN, and a green line also runs to the EGR solenoid valve.
- Which solenoid valve applies only to 49-state vehicles?
- The AIR D solenoid valve, connected with a YELLOW line, is marked '49 STATES ONLY.'
- What does FPRC stand for in this diagram?
- Fuel Pressure Regulator Control, which is connected to manifold vacuum via a RED line.
- What hose colors are used in this 5.0L vacuum diagram?
- Tan (vapor management valve), black (vacuum reservoir lines), red (manifold vacuum/FPRC), green (EGR), yellow (AIR D solenoid), and pink (AIR B solenoid).
- Where does the vapor management valve connect?
- It connects via a tan hose and dashed lines toward the fuel tanks and the carbon canister (carbon can).
