1989 Ford Probe Vacuum Hose Routing Diagram - EGR, Solenoid Valves, Canister

This document is a scanned vacuum hose routing diagram for an engine, showing an isometric line drawing of the engine assembly (including the air cleaner/intake duct, intake manifold, and valve cover) with vacuum hoses routed between emissions and fuel-system components. Labeled components include the air bypass valve, fuel pressure regulator, vacuum chamber, EGR control valve, charcoal canister, vacuum delay valve, and four solenoid valves: purge control, pressure regulator control, EGR vacuum, and EGR vent. Individual vacuum hoses are marked with single-letter color codes — B, W, R, L, and G — indicating hose color (black, white, red, blue/L, green by common convention, though the diagram itself does not include a color legend). A reader can use this diagram to identify the correct routing of each vacuum line between the intake manifold, solenoid valves, EGR system, charcoal canister, and pressure regulator, which is useful for diagnosing vacuum leaks, emissions faults, EGR problems, or fuel pressure issues, or for reassembly after engine work. The document contains no visible year, make, model, engine designation, or part numbers; it was uploaded as applying to a 1989 Ford Probe. The style is consistent with a factory service manual illustration.
