85 300D: Basic Hose Identification

[rbc]

Just found a 90% sheered off hose. Making a big mess. Cannot seem to find the name of the hose so I can replace it (or get the specs to replace it). It's the smaller hose within the photoshop red box (red box located just northeast of air filter assembly in picture) coming from the turbo side -- the little one running from the top left of the box to the bottom right).

See image. Thanks.
