Smog Pump Check Valves

[Yank Yarborough <102557.1565@domain.elided>]

IH all,
While driving to work this morning, My Scout sprang an exhaust leak. The
Smog Pump check Valve has rusted off the manifold tubing. I'm not sure that
I am calling it by its correct name, just using the Autozone parts persons
name for it. Of course, they don't have a listing for it. I seem to
remember someone posting an alternative part to replace the stock IH part.
Has anyone else run into this problem? How did you fix it?
Thanks in advance,
Yank
