dboisen Posted March 16, 2015 Share Posted March 16, 2015 Have an 89 xj 4.0 6 cylinder and the fuel injectors are leaking. O rings are fine. I've heard the 746 volvos are good but what years work? Are there any other jeep injectors that are a good swap? Link to comment Share on other sites More sharing options...
88mjblue Posted March 16, 2015 Share Posted March 16, 2015 You want to look for Bosch # 0 280 155 746 These are the best for the Renix 4.0s. They were found in volvo's, but Bosh was the manufacturer. I would search for them by bosh part number above, some on eBay, something like this: http://www.ebay.com/itm/121343759313?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT Try to find some that have been cleaned, tested, and have all-new o-rings, pintles, There is also a guy on cherokee forum that sells sets of the 746's remanufactured and tested for a similar price. I emailed him, but never heard back, and ended up buying a cleaned/tested set on eBay for about $80 for 6 injectors. Link to comment Share on other sites More sharing options...
boardmanMJ Posted March 16, 2015 Share Posted March 16, 2015 Correct me if I'm wrong but I was looking to replace my injectors as well and I was told that the Volvo injectors are a two piece injector and can possibly leak. I went with 98 dodge neon injectors but I have yet to put them in. Link to comment Share on other sites More sharing options...
dscowell Posted March 16, 2015 Share Posted March 16, 2015 Volvos, neons or mustangs. I have volvos and get a little better mileage and can speed up a little faster as well. I've heard volvos are best for renix that's why I went with them. Do some research before you make a decision. I know there is quite a bit of stufft on cherokeeforum.

SJBrooks Posted March 18, 2015 Share Posted March 18, 2015 I did a search for "replacement fuel injectors", and found an old post that contained this source: http://precisionautoinjectors.com/collections/jeep-injectors/products/bosch-3rd-generation-4-hole-upgrade-ev6-fuel-injectors-for-1987-1995-jeep-4-0l-engines Has anybody tried these? If so, what positive or negative experience did you have with them? Thanks, Steve Link to comment Share on other sites More sharing options...
cruiser54 Posted March 18, 2015 Share Posted March 18, 2015 Correct me if I'm wrong but I was looking to replace my injectors as well and I was told that the Volvo injectors are a two piece injector and can possibly leak. I went with 98 dodge neon injectors but I have yet to put them in. I'm correcting you because you are wrong... The Renix injectors were 2 piece and prone to leaking at the crimp/seam.

cruiser54 Posted March 18, 2015 Share Posted March 18, 2015 Get the 746s. They work the best. Link to comment Share on other sites More sharing options...
88mjblue Posted March 19, 2015 Share Posted March 19, 2015 Are there any additional o rings/seals within the fuel system that I should replace while I'm at it? Link to comment Share on other sites More sharing options...
cruiser54 Posted March 19, 2015 Share Posted March 19, 2015 Not unless you remove the fuel hoses from each end of the fuel rail..... Link to comment Share on other sites More sharing options...
SJBrooks Posted March 19, 2015 Share Posted March 19, 2015 Hi all, I'd really appreciate if somebody knowledgeable on the subject would comment back about my previous post (#5 above). My truck is an '88 5-speed. Thanks in advance for the help! Steve Link to comment Share on other sites More sharing options...
JeepsOLot Posted March 19, 2015 Share Posted March 19, 2015 What's odd about that eBay auction, SJBrooks, is, it only has Mopar injected Jeeps, 91 and above, listed. I was under the impression that these could be used in Renix injected Jeeps as well. Jerry Link to comment Share on other sites More sharing options...
HOrnbrod Posted March 19, 2015 Share Posted March 19, 2015 They can be used on Renix models if you use the EV1 Renix harness connector to the injector EV6 connector adapters, which are included in the auction in post #5. Link to comment Share on other sites More sharing options...
cruiser54 Posted March 19, 2015 Share Posted March 19, 2015 Having used Precision's in 3 Renix Jeeps and the 746 Volvo injectors in 1 Renix Jeep, I would never use anything ever again but the 746s. Link to comment Share on other sites More sharing options...

SJBrooks Posted March 20, 2015 Share Posted March 20, 2015 I too thank all for the replies so far. Further questions: 1. Are truly new 746 injectors available? 2. If yes, from where? 3. Will that source have the connectors needed to adapt the injectors to the stock wire harness? Thanks again all, Steve Link to comment Share on other sites More sharing options...
dscowell Posted March 20, 2015 Share Posted March 20, 2015 You can find used ones on eBay in decent conditions and get a rebuild kit and they be just fine. And you don't need to adapt them to the wiring harness it's all plug and play. Link to comment Share on other sites More sharing options...
Tommy Posted March 20, 2015 Share Posted March 20, 2015 I just bought a set of 6 from eBay for 45 bucks and a rebuild kit for 15. I'm doing the fuel filter and an ignition tune up at the same time. Should be a pretty straight forward way to smooth running. Link to comment Share on other sites More sharing options...
cruiser54 Posted March 20, 2015 Share Posted March 20, 2015 Easy peasy. Contact "programbo" on Cherokee forum for the Volvo 746 injectors. Link to comment Share on other sites More sharing options...
HOrnbrod Posted March 20, 2015 Share Posted March 20, 2015 ^^ This. I got a set of Bosch 0280155703 "Neon" injectors from him - good guy to work with. Link to comment Share on other sites More sharing options...
