Complete renix vacuum diagram?

[1990XJ4x4]

Does anyone have or know where to find a complete vacuum diagram for the Renix engines, I am wanting to replace all of my old vacuum lines and make sure everything is the way it is supposed to be. When I bought my 90 the previous owner was good at messing little things up under the hood. I keep finding vacuum lines with screws stuck in the end.

1) Check for an emissions sticker on the firewall (usually, in front of the driver's seat) - it would have the same vacuum diagrams that I have scanned, but don't recall where they are...

2) If you just want to replace vacuum wiring, go to NAPA and get it from there. It's going to be in their Echlin catalogue (and part numbers are posted here somewhere) and it only cost $50 each for me to do two vehicles three months ago, in the SF Bay Area (where parts cost twice what would be considered "expensive" everywhere else but Alaska and Hawai'i.) You'll need to get three kits - they were $52 all up, as I recall, and once you join the two major kits (there's a junction block that goes at the front corner of the intake) you can infer where everything else went - it's all preformed.

How much can the previous owner have screwed things up, anyhow? The RENIX vacuum wiring is pretty simple - considering the vehicle era - and is almost all necessary...

Are there any diagrams out there of all that vacuum wiring so that I can just replace the pieces that need to be.

Have you looked for your emissions tag? They're required for emissions control - not having one in CA is usually grounds for a failure - even if everything works up to scratch.

Failing that, I can see if I've got a scanned copy to forward - but I'd say to get the kit anyhow, no sense in keeping possibly faulty vacuum wiring if you think it's faulty, and fairly cheap to replace.

The three part numbers from NAPA will replace all of those EXCEPT:
#1 - Carbon Cannister Purge Line
#7 (line) - MAP Sensor

But what about the vacuum lines for the heater controls and the vacuum bottle up front? lines to the transfer case and front axle disconnect? These aren't in that diagram.

Thats what he ask for.

Not trying to high jack this thread but is #1 a vacuum line? Does it connect to a barbed end into the intake manafold?

I's a hard plastic line, it changes to hose and then connects to the vacuum tree.

If I connected that to a vacuum would that let the a/c blow out the front vents not just the defrost?

No the line I was talking is only for the fuel evap system.

Oh okay I have a different problem then. I do need to connect that but I also have to find out why my a/c, vent or whatever only blows out the defrost..... thanks.

Well make sure you don't have a big leak where it's supposed to be connected.
The vacuum line that goes through the firewall is the one for the heater controls.

Check the vacume lines at the bottle, in the front right corner of the front bumper. That's usually where they break causing that.

As well if it comes disconnected at the back of the unit, you'll get the same result. Found this when I knocked mine off.

Not to hi-jack or anything but looking for the same thing. Been having a bit problem with my vacum disconnect going in, but then it seems to not be in 4WD, like it slips out or something. Have checked the diaphram, and all the lines up to where it joins beside the valve cover. They're all fine. Replaced the rubber boot where the lower lines connect to the metal hard lines just to make sure there's no leak there. The other strange thing is that with the heater, I noticed that when on heat or bi-level, the floor vents will only blow cold air. Are these connected??

I've seen mention of a line that goes to the TC, and that where it connects that can cause problems. What does this look like? and what am I looking at $$ wise for it? Need to get my 4WD working asap.
