Where does this Vac line go?
92 302, two vaccum lines come off the top of the upper manifold together, one goes to the fpr the other continues around to the back of the manifold, I can't see what it connects to. Any ideas, it's one of the plastic red lines attaches somewhere around the back of the manifold. The line is broke on mine can't see where it goes....

the red ones go to control the AIR system if I remember right. Look on the inside of the hood above the heater box and there should be a diagram.
If I remember right it goes all the way behind the plenum and down the LHS of the motor to the coffee can on the wheel arch. in the middle of this line is a Y piece and a line runs back from here to one of the valves near the coil.
There are white, black, red and green lines if I remember right. Green is EGR?
I worked it out through feel and if you lie on top of the plenum you can see down between the plenum and bulkhead/ firewall.
can you view this url?

The lines do have a habit of failing and will go brittle. Replace with 4mm OD Nylon airline.

Thanks I will have to try laying on top. The diagram just shows the line to the fpr and not the other line, would this be in the Haynes manual? I have one around here somewhere just need to find it....

Can't remember if the Haynes book of lies will have it. The best place is the under hood sticker. If you get stuck I could try getting a photo of mine when its daylight and not tipping it down with rain again.
