For that price I doubt that you could be making a bad purchase. Let us know how it works out for you.

The oil less pump will be very noisy. The other looks old and well used. I suggest you go to the Gast web site and look up the model for the used one. It will explain how you can purchase parts and rebuild and old vac pump. You will also need gauges. Some folks also use filters. The pump is just the beginning.
