Vacuum line routing

Lane478 · Oct 28, 2007

I got the shaft. A local tuner did what they called a pvc "mod" to my 94 gt to help it pass emissions. They pretty much stripped out my vacuum lines, plugged some, and introduced a bad vacuum leak. I have since tried to put the pvc and vacuum lines back to factory, but I have not been able to find a complete list of the routing for them. What I really need is a list of all lines off the intake and where they go. Here's what I know is there, but not which port the go to and which lines connect on the same port. The pcv line, the line to the driverside vacuum tree, a line that goes to a four line block that has something to do with the egr on the right inner fender(that bunch of crap goes to the inner fender well), a line to the egr, the fuel pressure line, and a line that I don't have that goes to the vapor canister, which coincidentally, I also believe I need to fix but have no idea how to. I might have forgotten some. You can see that I need some laymans terms. like "this line goes from the small port on the bottom of the intake to this connection that looks like this by the (fill in the side of the engine compartment) side thing-a-ma-jig.

I got another issue. Right by the connector where you pull codes on the passengerr side and going into the wiring harness behind the a/c lines is a small black cylinder about two inches across and three inches long. It has what looks like a vacuum port on the bottom with no line. It about the size of a can of beanie-weenies, only skinnier(and without the pull tab.

) What exactly is that thing do? Sorry for the vagueness, but I'm fifty miles from home and working right now.

Thanks for the help.

That "cylinder" beanie wienie can thing is your canister purge solenoid for your evap system. It goes from the intake, to the solenoid, to the canister in the fender. You already named off all the required vaccum hook ups off your intake so you're good there. Let us know if you got any other hook up questions.

I'm glad you answered. I've read your stickies on the subject, but I don't know which port these items go to and which should be on a t and which should be straight to a port. Pictures would be a great help, if anyone has some that shows the routing on these.
