  1. Cruiser I installed each of these vacuum parts but my hoses from the egr solenoid to the egr valve are different. Mine run from the solenoid to the vacuum housing and then back to the egr valve is this okay or did I do something wrong?

  2. It does but the two doorman products up top are made a little differently than the diagram but I think it works the same.

  3. According to the napa and dorman websites these harnesses do not fit a 1987 Cherokee 4.0. They do look very similar but do you have any experience using them on an 87? Didn’t know if they could possibly be used with some modification?

  4. Word to the wise (which leaves me out, unfortunately), if you buy one of these new vacuum harnesses… Inspect it thoroughly before installing.

    My new NAPA harness was broken, and I didn’t notice. In short I installed a brand new vacuum leak!

    I have no idea if the pic will work, worth a try I guess.


    Took me a while chasing running issues before I found this, it was the line for the EGR system and a ways down on my diagnostic protocol.

  5. So my question is… and I’m new to renix btw. If I but the front and rear does that mostly cover all the vacuum lines (say suspected vacuum leak) or is there more to it than that?

  6. My Comanche dies random when coming to stop sometimes, turning and accelerating also has a hiccup when driving at a constant speed cuts in and out almost kind of annoying any suggestions?

  7. He cruiser, I have narrowed my issue of the heat not working down to the the heater control valve not getting any vacuum, Any idea how to get vacuum there or where that vacuum hose routes to?
