Eagle Posted March 31, 2018 Share Posted March 31, 2018 My '88 XJ has been off the road since my wife died four years ago. Now that the snow has receded, I was able to get underneath and patch the fuel leak -- I thought it was a gas line, turned out to be the metal fuel filter had rusted through. Got that all fixed, tried to start it this morning -- and all six injectors are leaking. What's a good source for injector O-rings? Link to comment Share on other sites More sharing options...
MuddFoot Posted March 31, 2018 Share Posted March 31, 2018 Rockauto.com or Napa but I'd go ahead and change the injectors. Order off Amazon or eBay you can get a set for about 60 bucks and comes with o ringsSent from my Z981 using Tapatalk Link to comment Share on other sites More sharing options...
HOrnbrod Posted March 31, 2018 Share Posted March 31, 2018 Mopar p/n 83503637 for your 4.0 Renix. Ebay, Amazon, etc. Probably the regulator will need new rings too... https://www.amazon.com/Cherokee-1987-1990-Motor-Injector-Replacement/dp/B00B7CQW2K/ref=sr_1_3?s=automotive&ie=UTF8&qid=1522515414&sr=1-3&keywords=83503637 Link to comment Share on other sites More sharing options...
Jess Posted March 31, 2018 Share Posted March 31, 2018 If you haven't already you might consider upgrading to 4 or 12 hole injectors. I've been using these 4 hole injectors for a few years now, they're great. But apparently, 12 hole injectors are all the rage now. Link to comment Share on other sites More sharing options...
fiatslug87 Posted March 31, 2018 Share Posted March 31, 2018 If you only need the o-rings, get NAPA part CRB212079, all 12 o-rings and a little tool for easy installation for only $6. Link to comment Share on other sites More sharing options...

The best $52.99 I've ever spent on my MJ. https://www.amazon.com/gp/product/B01N302XMZ/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 Link to comment Share on other sites More sharing options...
Eagle Posted March 31, 2018 Author Share Posted March 31, 2018 Yeah, I know. I have no idea how much longer Old Faithful can last, but I doubt it'll be more than another year or two. I would like to make 300,000 miles (it's now at 287,000). I really didn't want to sink any more money into it, but I remember that the Renix-era injectors are known for separating between the metal and plastic body, so I girded my loins and ordered a set off Amazon. Which means I can't get it running this weekend. Link to comment Share on other sites More sharing options...
