1994 Ford Bronco Vacuum Hose Routing Diagram - EGR, Thermactor Air, CANP, FPRC

This document is a vacuum hose routing schematic (typical of a Vehicle Emission Control Information / VECI diagram) showing the emissions and vacuum system layout as viewed with the front of the vehicle at the bottom. It depicts the routing of vacuum lines between major emission components: a fuel pressure regulator control (FPRC), an air-management valve directing air to AIR B (air bypass) and AIR D (air diverter) circuits with connections to the engine (ENG) and catalyst (CAT), two solenoid valves (SOL V) controlling AIR B and AIR D, the EGR valve mounted at the throttle body, an EGR vacuum regulator (EVR), a manifold vacuum (MAN VAC) source fitting, the carbon canister (CARBON CAN) with a line to the fuel tank(s), a canister purge solenoid (CANP), a vacuum reservoir (VRESER), and a takeoff to the A/C system. Solid heavy lines, hatched lines, and dashed lines distinguish different hose types/circuits. A reader can trace which component connects to which vacuum source, useful when replacing hoses or diagnosing vacuum leaks and emission control faults. The diagram contains no part numbers, calibration codes, or explicit year/engine identification on the visible image.
