Part number for hose coming off top of '99 throttle body (1 Viewer)

While cleaning my throttle body on my '99, I noticed this gasket has a crack threw it, so I need to replace it, anyone know the part number?

I don't see it on the diagram. Was that port covered with a cap? I'm not with my truck to check. If so I think isn't a part# for it. It would just be considered part of the complete throttle body, not a sub assembly.
