Help with emission/vac hoses after fire

I bought a 91 Wrangler 4.0 5spd recently that had a engine fire that toasted FI wires along with vacuum hoses/fittings. I have replaced injector wires and tried to determine how vac lines were connected even though some hoses/connections were melted. What I would like is some pictures of stock engine compartment and emission/vac routing. I will also put a request in classifieds to purchase hoses and fittings. I just replaced CPS and it now starts but has to be shut off immediately cause it goes to max RPM. I would be interested in your opinions on what causes this, vac lines not connected or wrong or something else. This is my 1st Jeep and I would like to get it on the road without blowing motor. Any help would be appreciated. Thanks, George

Here is the one for a 1993 with the 4.0. It ought to be the same as your 1991.

kloppk, thanks for the diagram, that should get me started with hoses and fittings I have. When I get more parts at least I will know where they go. shaun1300

Sounds like you are good to go. Here is a pic from my '93 if it helps.

Pictures

Louie4, Pictures helped a lot, especially the second one. I need to come up with the fittings and hoses and run them properly but now I have way to tell where they go. Anyone have a pix of hoses/fittins for 91 4.0 5spd or are they same as 93. Thanks, shaun1300

If you have a junkyard nearby see if they have a Cherokee with a 4.0L. Most everything is the same except the airbox but the vacuum hoses should be what you are looking for. I may be able to dig up some other pics.

Cherokee

I bought a 2001 Cherokee 2 weeks ago with cracked block and had engine replaced. Plan on swapping over hoses that look like they will work on a temp basis. I will go to Pick & Pull and see what they have as well. Thanks for advice. shaun1300
