vacuum line diagrams

Knowing a whole bunch more about jeep cjs than yours

Are you sure it's not a "vent" for one of the drive train components (it might even have a plastic-like cap over the loose end where fresh air can enter?

Other than that

I did go into "prodemand"

I found "only" 2 vacuum diagrams that showed up for a 4.3l

They are at the bottom

Hi, I need to replace all vacuum lines on my blazer due to age and deterioration. I would appreciate it if you could supply me with a routing diagram for vacuum lines as I've had to remove and plug a couple of the the lines and am now not sure of the routing. Thank you, Mark

I can not figure out where the vacuum hose that runs
the door in the heater system to trip from defrost to
panel vents. I was checking the vacuum hose under the hood and the hose came off from somewhere and i
have looked and looked but can not find a place to connect hose

Do you mean you have a loose vacuum line under the hood and are looking for it's connection? If yes post the location where it comes out of the fire wall and I'll look it up. I've got a 97 myself, but there are a few lines under there.

I was just wondering if the vacuum hose was a normal rubber hose or something different

the vacuum hose is like any other one you can buy in a store. there are cases where there is pressure involved and those hoses are made heavier.

there are 3 vacuum lines that run from the top of the tranny,what are they and were do they go?

They are for the transfer case. Heres the diagram

can you tell me where on the engine point (a) connects to.

I am replacing a motor in my buddy's blazer, and need a diagram of the entire motor. Anyone know where I can find one?

what exactly you need diagram for? vacuum lines, ground wiring, ...etc..?? not really sure what you need but below are couple of pics for the engine..

Thanks so much. This helped tremendously. I still have a couple of hoses that I'm not sure of, but I don't know if they would have a super detailed diagram of those.

Thanks again.
