Thanks, Loren. For once I did in fact do the troubleshooting in advance, everything is good as far as vacuum pressure (at least, with an isolated engine bay) until I put the pump directly on the shutoff. Once there, I can neither draw a significant vacuum by hand with the engine on or off (pump - coupler - vac tube - original coupler - IP), nor can I shut down a running engine by hand or by engine vacuum.
The only oddity is that I was expecting to also see oil, but maybe since it got bad very quickly I've been lucky.
