Where is the check valve located in the smog system?

The check valve is shown inline between the smog pump hose/diverter valve plumbing and the right-hand injector pipe leading to the exhaust manifold.

Is any part in this diagram year-specific?

Yes, the right-hand injector pipe is labeled '75-76 RH Injector Pipe,' indicating it applies to 1975-76 vehicles.

How does the smog pump pulley attach?

The exploded view shows the pump, then a pulley spacer, then the pulley, secured with a bolt; the pump is supported by a brace and bracket bolted to the engine.

What valve is mounted on the engine near the intake in this diagram?

The EFE valve is labeled on the engine, and the diverter valve is shown mounted near the smog pump hose and elbow.

This document is an exploded parts diagram of the Air Injection Reactor (A.I.R.) system, apparently from a Corvette parts/reference catalog. It shows the emissions air-injection components mounted on a V8 engine and identifies each part with callout labels. Labeled components include the air (smog) pump, pump pulley, pulley spacer, mounting brace and bracket, smog pump hose, elbow, gasket, check valve, diverter valve, EFE valve, an injector pipe, and a right-hand injector pipe specifically labeled '75-76 RH Injector Pipe.' The drawing illustrates how the pump assembly (pump, spacer, pulley, and attaching bolts) fits together, how the brace and bracket secure the pump to the engine, and how the hoses and injector pipes route from the diverter/check valves to the exhaust manifolds. A reader can use this diagram to identify part names and relative locations when disassembling, repairing, or restoring the air injection (smog) system, and to see the assembly order of the pump pulley and mounting hardware. The only year-specific note visible is the 1975-76 designation on the right-hand injector pipe; no other years, part numbers, or torque specifications appear in the image.
