GM 8.1L EVAP System Hose Routing Diagram - Canister, Tank & Vent Lines

This document is an unlabeled line-art routing diagram of an evaporative emission (EVAP) system, filed by the uploader as the '8.1L EVAP route.' It contains no written legend or text other than ten numbered callouts (1-10) pointing to system components and hose runs. The diagram shows a fuel tank (callout 5) partly filled with fuel, with a rollover/vent fitting on top (4) and a fill/vent pipe with a flared opening (3). Vapor lines route from the tank to a large EVAP canister assembly (2). Two small rectangular components, likely solenoid valves (1 and 6), are connected into the hose network, with individual hoses and tubes identified by callouts 7, 8, and 9, and an open vent fitting at callout 10. A reader can learn the general plumbing arrangement of the EVAP system, how the tank, canister, vent, and control valves are interconnected, but because the source page carries no legend, exact component names, part numbers, years, or model applicability cannot be confirmed from this image alone. The diagram would typically accompany a service-manual legend page identifying each numbered item.
