Loose vacuum hose...help!

[Les Huckins <jhuckins@xxxx>]

Vacuum input hose from the thermal control valve not connected (#26 on
the emission/evap control parts sheet) to the manifold. Only place that
looks logical is what looks like a grease fitting below on the
manifold. Shouldn't there be a typical hose fitting there? No vacuum
is coming out of the fitting, do you suppose someone stopped it up in
order to disable the vacuum advance? But then, why leave the hose loose
(unless it will no longer fit over this fitting)? Is there any other
possible reason for this manifold fitting? If this is the wrong one, is
there a part # for the correct one? Is there another answer entirely?
Thanks.
