I'm getting rid of the smog/air pump, but where do the two vac. lines go? I see that they both feed into a loom that contains a couple other vac. lines, and then goes into the fender, and somewhere by the intake. What should i do with these? I have to hook the pump back up in two years, but won't it push enough air without the vac lines? I only would need it to pass a test once, so if i have to, i will either rip the lines all the way out, or just block them off on one end. What do you guys recommend?

ha, no problem! I know people usually just plug them, that much i have found so far, but do we have to? I'd rather pull them, but then again, i would have to put it back on in two years, and i don't want to be TOO confused as to where they go.
 
94 blue...if this is temporary than use some golf t's to block the lines and then wrap it with tape or a wire loom to hide it .....I removed mine for good.....

5.0 I have know idea what your talking about, you need to be more specific....
 
This is what they are:

Red - Vac feed to EGR solenoid, AIRB solenoid, AIRD solenoid. These valves are in the passenger fenderwell. The red connects to intake at the fitting that the fuel pressure gauge connects to. It supplies vacuum for the EGR, AIRB, and AIRD valves. The ECM turns on and off the solenoids to contol those valves. Remove the red from the intake, none of these will work.

Green - Output of the EGR solenoid. Sends vacuum to the EGR valve when the ECM opens the solenoid.

White (or Tan) - Output of the AIRD solenoid. Sends vacuum to the AIRD valve when the ECM opens the solenoid.

Tan (or White) - Output of the AIRB solenoid. Sends vacuum to the AIRB valve when the ECM opens the solenoid.

Not sure which one the white and tan ones go to. The way the lines are bent should tell you which is which.


If you are not running the smog system or the EGR, you can remove the red line from the intake and put the vacuum harness on the shelf. Plug that fitting on the intake, of course.

If you are running the EGR, you need the red connected. I'd plug the white and tan as the ECM might still open the solenoids and cause a vacuum leak.
