Ok, in my stupid ifinite wisdom I have disconnected some vacuum lines. I have marked one end but forgot to mark the other end. I need to find out where the other end attaches.
1. I got a vacuum line where one end attaches to the intercooler. Where does the other end go.
2. I have a plastic vacuum line with one end marked upper intake (it has a rubber vacuum line at that point). Where does the other end go?
I'm sure as I go along I'll have some more questions on these vacuum lines.
Thanks,
Gary Schweikert

#1 intercooler. The long hose goes to the vacuum tree. The short hose goes to the inlet tube on the compressor housing.

2 Upper intake. If this is a relatively large diameter, long hose, it goes to the vacuum tree. It's the main source line from the upper intake. If it's a relatively small diameter hose, short, with a metal tube in it, it goes to the FPR. Both of the above hoses connect to the fitting on the front, upper part of the upper intake. If it's a larger diameter hose that connects to the underside of the upper intake, then that goes to the PCV valve.
