IIRC this pump is about 30 years old, bought at Grainger back when.  I assume Speedaire or Campbell Hausfeld, but who knows?  I have no further info other than the pictures.  Crank case appears to have a casting number, no other identifiable numbers on the pump

Seems to be leaking air from the intake port once the tank is filled.   The exposed valves, in the photo, are rusted (heat) and slightly bent up.  This maybe the source of the leak.

Assume I need new valves, gaskets and filters for the top end.  If option, I'd like to buy a better air intake filter solution...foam and mesh doesn't seem good.

Thank you in advance....

Well that didn't work well....no photos uploaded.  Any clue why the photos didn't upload?
