  1. TJ Technical Discussion
    I want to replace all my vacuum lines. I've done a bunch of searches, but "vacuum lines" is too broad of a search and I think my simple mind can't narrow it... Here's the question: Can someone tell me what size lines I need. I am not concerned with lengths...inset joke here :)... I plan to...

    Hey guys, So a few weeks back I posted here asking for help getting my air vents to stop blowing out of my windshield vent. This has been one of the projects that's been on my list of things to get to. Trying to fix this on a 05 TJ...AC was stripped from the engine when I got her (although the...

    First timer great to be here thanks for having me. I worked for Harley Davidson for 25 years very mechanically inclined. 1993 YJ If I disconnect the TC switch vacuum line(s) plug to do some driving tests, will it cause any drivability or vacuum issues elsewhere that I need to head off at the...

    So while installing highline fenders I had to move around some parts of the emission control system: Evap Canister, Leak Detection Pump, Leak Detection Pump Filter, and Evap Purge Solenoid. The lines are pre-bent to fit in the stock configuration so when the components are relocated the stock...

    My vacuum lines melted from resting against the actuator motor.

    So I have the typical heater vent problem where it's only blowing out of the defrost. After following all my vacuum lines under the hood and finding no problems, I took a look at the actuator motors and found my problem. Two of my colored vacuum lines that connect to the actuators had been...
  9. TJ Technical Discussion
    So while doing some maintenance on my TJ today, I noticed under the IAC/Throttle body that it seems I'm missing a vacuum hose. I can't find any diagrams showing what it is and where it connects to, so I'm including some pictures of what I mean. Let me know if you have the knowledge I seek :)...
  10. YJ Technical Discussion
    Okay folks. Ran into a problem the pother day. I was riding down the road and my jeep (92 yj 2.5, 5speed) decided to act like it was running out of gas. MY gas gauge does not work so I have run out of gas a few times in it and know exactly how it feels. The problem is, i had just put 20 bucks in...

  12. YJ Technical Discussion
    Can anyone send me some actual pics of a working vacuum line setup for the 4.2. Just put a new motor in a Jeep for my friend, I rebuilt the carb, but there wasn't any vacuum lines on it, and I need to put them back in. The carb needs adjusted and without the proper vacuum lines I fear I will be...

    After much study and rerouting of vacuum lines, here is a diagram of how they should arrange on a 4.2 YJ. Notes on the drawing show what can be eliminated if you do the Nutter bypass.

    Anyone know what this hose is for and where does it connect to? It appears to go up near the rear brake line area in front of the rear axle. I do not see any line with no hose on them though. Thanks, Scott

    DIAGRAM NEEDED VACUUM LINES TO ENGAUGE THE 4WD. Does anyone have a good diagram for an 88 JEEP YJ 4.2 I6 4WD System. I've got some vac lines cut and dont know where the one from the manifold goes into the front axle. Thank you for all the info.
  16. YJ Technical Discussion
    I have replaced all the lines after my dad removed them all. I probably dont have them in the correct locations. Need a diagram very bad. When it starts it will idle but very rough and smokes pretty bad white smoke. when you press the eccelerator it is very sluggish. Has new accel plug wires...
