Vaccume Lines 1985
I could use some help with routing of vaccume lines on my 1985. I believe there are four vaccume pickups ont the plenum / throttel body. One runs off the bottom of the throttle body it "Ts" and one line feeds vaccume to the canister in the left front of the car and the other feeds the EGR control valve mounted on the right rear of the engine a line then runs from the valve to the EGR valve. There appears to be an attaching point on the rear of the valve (two metal clips) does a line go to this attachment point and if so where does it run. The second pickup point is on the left rear side of the plenum and feeds the power brakes. The last two pickup points are on the right rear of the plenum. The rear most has a valve/"T" and feeds the heater/AC controls and the cruse control I believe. The front one of these two is the one I need help with the picture I took is not real clear but it appears to "T" and one line runs back and under the plenum I would think to the FPR is this correct? The second I see runs to the front but I can't see where it goes can some one check their car and let me know? I guess I should have taken a few more pictures!

Here is an 86 vacuum diagram.

My 89 also has the diagram on the radiator shroud. On my car there is nothing coming off the back of the EGR solenoid, those 2 clips sure make it look like there should be,but the diagram above shows nothing either...WW

I believe the clips at one time held a mesh like filter that after time disappears. But I’m with you it sure dose look like it clamps a vacuum line to it, however that part is hard to fine been discontinued for a while.
