talon bypass/ check valve

Now that ive finally gotten around to installing the FMIC and the talon bypass valve, I am having the famous partial throttle studder and vacuume leak at idle. I hear that one fix for this is a check valve. How is the check valve installed in the system? Is it installed in the vacuume line to the bypass or is it on the outlet so air cant be sucked in?

I have searched for the answer here and at turbo ford, but I can find VERY little info on the setup.

And I would post my old pictures, but the board won't allow me to upload images...

Sorry.

Thanks Natmac!

I went to a hardware store and bought a brass check valve. The car seems to idle better but I still have the partial throttle stumbles and there is still a slight idle problem. Maybe thats becasue its not plumbed back into the intake yet.
