vaccum port

[dan2286]

I cant answer your question but is there a vacuum line routing diagram on the fan shroud?

I am having a hard time telling which one you are talking about there. I had a similar port on my GP, but that was a SBC. The only line i can think of right now went back to the vaccum modulator on the trans.

can this one go to the carb? cause what you see in the pic it's hooked up to the vacuum ball for heat but i changed things to what the manual said from the firewall Grey line to the water heater, and the other line to the vacuum ball, and there suppose to be a line going from the vacuum ball to the small engine port on the driver side.. so i did that, but i'm not sure where the BIG vacuum port hooks up to, is it suppose to go where my arrows point to in the pic?

That port that looks like a bolt that your arrows are pointing to goes to a checkvalve, and vacuum ball for the cruise control......... the other small line at the back of the carb that your pointing to goes to the switch for the EGR and other emissions stuff............ at least it does on my car.........

I tried taking a pic of my emissions sticker but my camera sucks....... it turns out too blurry to really see anything....

if you can post pic not sure what's the same with yours an mine cause mine is an 80. right now i just got it plugged with a screw till i can find out where the hell it went

 

[joeairforce]

My bad..... its also A tee that supplys the vacuum to the heater control doors.... here a couple of pics though......





(my camera sucks......but ignore the blue engine..... i thought it would look better than the black when I put it back in....... i'm gonna repaint it back black next time I have it out)
