Refresh Emissions/Vacuum Hoses

[summerinmaine]

I'm trying to squeeze some more life out of my engine while I design/implement a running gear project, then do the stroker to satisfy my lusts. But I have persistent running problems that always seem to involve finding vacuum leaks here and there. Looking under the hood, all my hoses/lines seem to consist of a mare's nest of patches/kludges that connect the right-angle bends in the lines, or the size A to size B orifice step up/down mess that is the emissions system

 

Is there a "kit" or the like available to replace all the oddball rubber emissions and vacuum hoses/lines, so that I don't have to go nuts sourcing one weird hose/line after another? I see various "looms" advertised on eBay, tho not for my specific year MJ. So I'm getting really confused. :???:

Yes. Napa sells them. I think it's a front harness and a rear harness.

Thanks all!

 

I tried searching for the topic, as I knew it must have come up before, but I should have spelled it "vaccuum" or "vacume" I guess. ;)

For some strange reason the compatibility guides for the part nos. (Dorman 46003 & 46004) say they fit the 1988-1990 4.0L. So what's the 1987, chopped liver? I can't imagine that there was a major change from 1987 to 1988. Was there? :dunno:

87 was the same. I have an 87 , 88, and 90. All the harnesses are the same.

Arcata? I went to college there in 1972 to 1973.

Cool. My daughter's here as a grad student.

 

And thanks for the compatibility confirmation. Online guides in ads can do more harm than good sometimes.

My security screen freaked and said your link is buggy with malware. Is that another possible source for parts? If so, I appreciate it but I'm satisfied with the RockAuto source.
