Vacuum line goes to where?

[scottydog]

My son has been replacing vac lines and we can't figure out where one of them goes. It's a line coming off the rear of the intake manifold below the EGR temp sensor . I think it goes up to the EGR system but I can't figure it out from the vac diagram.

Been searching for a photo of this but no luck. Any ideas?

not sure if this is the diagram you were talking about, but it might help if it's not.

Thanks, I think I figured it out. Per the diagram there are two "T" vac connections under the manifold the the EGR valve. One connects the BPT valve/EGR solenoid/canister. The other seems to be what I'm looking for: intake manifold/svc valve/fuel regulator.

Hopefully this does it. EGR problems in these cars are a PITA!

Thanks!
