What vehicle and engine does this vacuum diagram cover?

It covers the 1987 Ford LTD Crown Victoria with the 5.0L engine, for calibrations 6-22L-R10, 7-22F-R00, and 7-22R-R00.

Which components are shown in this vacuum routing diagram?

FPR, MAP, VRESER (vacuum reservoir), PCV, EGR, EVR, VCKV, ACV, ABV, DIV and DMP solenoid valves (SOL V), CAT, AIR PUMP, CPRV, V-REST, FUEL TANK, CAN (canister), and multiple MAN VAC (manifold vacuum) taps.

What is the source of this diagram?

How is the diagram oriented?

The bottom of the diagram is labeled 'FRONT OF VEHICLE', so the layout is viewed with the vehicle front at the bottom of the page.

Does the air injection (thermactor) system appear in this diagram?

Yes — the AIR PUMP is shown connected through the ABV (air bypass valve) and ACV (air control valve), with routing to the CAT (catalyst) and ENG (engine), controlled by DIV and DMP solenoid valves.

This document is a scanned page from a Mitchell Repair Information manual (printed February 13, 2004; © 2003 Mitchell Repair Information Company, LLC) showing Fig. 5: a factory vacuum hose routing diagram for the 5.0L engine in the 1987 Ford LTD Crown Victoria, specifically for calibrations 6-22L-R10, 7-22F-R00, and 7-22R-R00, courtesy of Ford Motor Co. The schematic depicts vacuum line routing (solid lines for hoses, dashed lines for other connections) between emissions and engine-control components: the vacuum reservoir (VRESER), fuel pressure regulator (FPR), MAP sensor, PCV valve, EGR valve, EVR, vacuum check valve (VCKV), air control valve (ACV), air bypass valve (ABV), diverter and dump solenoid valves (DIV SOL V, DMP SOL V), catalyst (CAT) air injection, air pump, CPRV, V-REST, charcoal canister (CAN), fuel tank connection, and four manifold vacuum (MAN VAC) taps. The diagram is oriented with 'FRONT OF VEHICLE' marked at the bottom. A reader can use this page to verify correct vacuum hose routing for emissions and thermactor air injection system service on a matching 5.0L calibration. The page carries reference number 200741.
