I broke down and bought a rebuild. It's enough of a PITA to begin with. Got the hoses too. Vacume hoses were all snarfed up as well. I have it all torn down. The housing on the pump has a cast bolt hole that's snapped off. And...looking at the tear down so far, I bought a timing belt kit, as long as I'm in there, and no telling how long it's been; 278,000 miles on this engine, as far as I know. Cheap insurance.
