Mnh88xj Posted January 16, 2018 Share Posted January 16, 2018 I'm swapping in a 94 XJ 4.0 into an 89 comanche... I'm using the XJ fuel lines that go into the fuel rail, which don't hook up to the existing comanche ones. i thought i would try to buy the rear steel lines (that run along the rails and do the bend around the cross member) for a 92, assuming they would work since its the newer style. i just can't find any place that sells them. does anyone know of a place that sells these? or any custom ideas to get around this issue? thanks mike Link to comment Share on other sites More sharing options...

Pete M Posted January 17, 2018 Share Posted January 17, 2018 I was thinking there might be some info in the 97+ conversion threads that would be useful. Link to comment Share on other sites More sharing options...
kook911 Posted January 19, 2018 Share Posted January 19, 2018 When I did this I ran the HO lines to the fuel filter. At least for min they were just plug and play. I’ll try to grab a pic tomorrow. If I remember correctly you have to cut the Ho lines down to fit. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted January 20, 2018 Share Posted January 20, 2018 When I did mine(95 XJ into 89 MJ ) I just used rubber hose to connect the two steel lines together , this was before dorman came out with these ... https://autoplicity.com/187759-dorman-oe-solutions-nylon-to-steel-fuel-line-compression-union?gclid=EAIaIQobChMI2vX_jLbl2AIVRlgNCh3BWAHUEAQYASABEgJUzPD_BwE , they also have steel to steel connectors you can also take the 91+ lines off at a junkyard or buy the correct dorman lines ....

MuddFoot Posted January 22, 2018 Share Posted January 22, 2018 On mine I also just used the 95 Cherokee donor lines to the filter and then used everything else off the mj. But I'm using a Dakota tank and modified the rest to work with it. Sent from my Z981 using Tapatalk Link to comment Share on other sites More sharing options...
