The noise was indeed coming from the vacuum pump. Upon further investigation I realized it was cycling which does point to a leak. However, when I removed the hose and plugged it with my finger the pump stopped cycling and ran continuously. Then I noticed that the original vacuum switch had been bypassed and a alternate plumbed in. Apparently, the alternate has failed as well.
I see the original component is a GM unit. But, I'm not seeing anything on the usual parts site. Perhaps I'm not searching for the right thing...calling it a "vacuum switch". Any suggestion on a source for a new one?
