thats a lead, thanks george.

I took a look around where indicated both under the hood and even the wheelwell but nothing looks out of order. Everything looks at least clean and new, actually. Nothing looked like it was a vacuum reservoir. I found the housing to the smog control paraphernalia but I didn't open it. Doesn't seem like it shoud be in there-- as I write this I'm thinking I should open that housing and have a look. If anyone is more familiar with the 129 vac reservoir location/connections, please advise.
