The "Y" I messed with is the one you're talking about. It sits on top of the valve cover and connects the vacuum supply on one of the shorter legs, the transmission on the other shorter leg, and the longer leg of the "Y" goes through the vacuum switch on the valve cover to the injection pump throttle position vacuum release. The more throttle you give it, the more vacuum is released and the vacuum to the tranmission goes down.

I need to know in which leg of the "Y" the restriction goes. I'm almost certain this Y doesn't have a plastic ring anywhere, but I'll look again.

Thanks for any help
