Vacuum Line Set?
 

Does anyone know of a company that sells a complete vacuum line set for an 88 4.0?

napa sell themhttp://www.comancheclub.com/forums/v...hp?f=2&t=29751

just replace em with regular vacuum lines, a lot less cluster****y than that OEM hose set up and cheaper.

LOL, I ripped most the vacuum crap and smog off mine today. Most of its trash anyhow. Unless you live in a smog compliant state. I dont.

if you remove vacuum lines your going to have serious leaks and issues.

to the OP running basic vacuum line in place of these overpriced brittle plastic lines will not effect you emissions, seeing as your stuck in california

Doubt that. Less vacuum lines, less leaks. All I removed was the smog stuff and AC. Im a mechanic, this aint the my first rodeo. I know what to remove and not to and what to plug off.

don't go and buy that vacuum harness, just trace out where the lines go and take the time to cut proper lengths it will clean up under the hood and and that stupid little box where the two halves meet is just going to break again and since you are in CA like me as long as things are hooked up and working it all good.

My YJ has almost no vac lines anymore. They were causing too many problems.

Thats why I removed the useless ones! Kept the ones for the PCV, Heater controls, MAP sensor, FPR. Got rid of the charcoal canister and that football behind the bumper.

I had to reroute all my vacuum lines when swapping to the 99+ intake manifold. Pepboys sells vacuum lines by the foot in about 6 different gauges in the parts department. Real cheap.

well the way you said it could give the OP that the idea vacuum lines are not needed and some of the vacuum lines are needed, especially since he is in california, jus cause your a mechanic doesnt mean the OP is, and im a heavy duty mechanic so :tt2:

Hahaha :laughing: Okay, then do you guys think that I should go with the pepboys idea?

Dorman offers the whole set up in 2 pcs [Front & Rear] available at any local parts store for about 30.00 for both sections. Check online at Rock Auto. Dorman Pt#46004 and Pt#46003

yes, just cut your own lines the original lines are a bad design and not worth the money

In california you cant remove anything! But yeah he could have misunderstood what I was saying I guess. Heavy duty mechanic? Whats that mean the parts weigh more? Mechanic work is mechanic work.

lol yea stuff i work on the big stuff......basically pay is better, and i hated working regular automotive than going home and working on my own vehicles, so its different enough that i can do it and still enjoy working on my own stuff

All right then, that's what I'll do. Thanks a lot guys! The forum never fails!

:cheers:

Always some shade tree mechanic got more knowledge and better ideas than the engineers who designed and manufactured it. Guess these opinions depend on whether you want to fix it right or half *** fix it. Thats why I have always preferred to work on my own ****. By the way to the guy who removed the football under the fender Does your heater blend door and your cruise control still work? Or are they not supposed be functional either? lol

Well if your referring to me. Read on, if not then disregard.

No, I removed the cruise.(Do not need it for offroading, its not a DD. And all the blend door needs is a vacuum signal. It doesnt have to be from that dumbass football. Think about it, where does that thing get its vacuum from? Uh, obviously it comes from a source connected to the intake manifold!!! All that thing does is redistribute vacuum! If you looked at a vac diagram then might know that. Theres your shade tree education for the day BTW!!!

And before you get your holier than thou hat on you should know who your talking to and what kind of mechanical background they have before you start pecking the keys on your keyboard. What Ive done obviously works. Or else I wouldn't have done it. All I did was delete stuff that is useless on my rig. Just because an "engineer" put it there doesn't mean the vehicle will not function properly without it. The first engineers were "shade tree"!

Im not suggesting everyone do what I did with my rig. Some states require this stuff to pass regulation.

The redo

Air box > vac switch

Air box > cap other

Air box > front top valve cover

Vac switch > fuel regulator

vac switch > EGR switch

Egr switch > EGR valve

Intake port > dedicated vac line for HVAC (or vac ball under bumper)

Intake Port > Rear top valve cover

-----------------

That just about covers it. Enjoy.

Cool it. We mechanics do this for a living, we know the laws and we are trained to follow them. In some cases where improvement can be done to an existing system, it should be done.

Everything was cool, till Driv1923 spouted off. :surrender:

:thumbup1:

BTW MODERATORS: This should be sticky-ed. this is the proper way to re do the vacuum harness on the Renix 4.0 liter.
