new o-rings are about 2 bux from autozone. easy to pull apart and replace.
it's usually just the upper o-rings that need replaced.

on a side note, i got some 703 injectors from the junkyard for 10 bux. great shape, like freakin new. i just threw in new o-rings on top and better than ever.

just poke around the yard for someone that paid the cash to replace them just before they junked it. you might just get lucky.

It's leaking from the body. I pulled the fuel rail a few months ago and used a chem-resistant two-part epoxy to seal the injector body. That worked until just the other day. I could just do the same thing again and get a few months out of it but if I'm gonna pull the rail, I'd rather just replace/upgrade.

Are the 703s Neon injectors? Are they truly a direct swap on a Renix? No need for harness adapters? I've asked about this before but no one had an answer.

 

Yeah I figured you'd replace the o ring if that's all the problem was. And yes, the 703s are a direct swap for the Renix. There's a vendor that sells em here but if you have a JY close, I'd recommend doing that instead

 

Okay, good to know. I've got a friend out in the IE whose been wanting to make a JY trip out to Fontucky, somewhere, so I'll keep my eyes open for a suitable donor. Think I might yank the rail this afternoon and re-epoxy until my puny little tax check arrives. Better safe than... KABOOM.

 

On a side note, the PO gave me all of the maintenance receipts she had and one of them (from June 2011) was for replacing the injector o-rings. I'm guessing they did that because there was gas present around the injector(s), I'm also guessing the gas they detected was coming from the injector body and not the seals.

 

Good plan my friend. Better that than letting it leak all over the place

 

I ended up going it alone today at the JY(s). I hit up most of them within 20 miles and only scored four of the necessary six 703 injectors but they were only $2.50 each so I still left with a good feeling. What are your thoughts on swapping out four of them? Probably a bad idea, I know. Just don't want Heep catching fire :/

I'm kind of surprised at how few 4 cyl. Neons, Strati, Cirri, Sebrings, Breezes and Caravans have made their way to the scrap heap. Must be pretty reliable.

I only found two Cherokees, one was a 90 sport 2wd that had been gone over pretty well but I did score a $1 window crank so my passengers don't have to use that stupid Vise-Grip and I also picked up a full instrument cluster out of an '89 for $10. No sound bars or swing-out spares

 

don't put in just 4. go get another 4 so you have spares just in case one or two are bad.

and yes, direct fit. i've done it.

 

I knew you'd say that. Oh well, the search continues. I'll pick up another set of four as soon as I can get to another junk yard but in the mean time, have gas leaking out all over the place in my daily driver. What's worse, running with (4) 703 and (2) stock injectors or leaving them as they are? I'm gonna leave it for now and hopefully find more tomorrow, even though I can't afford to take another day off work. Dammit.

Does anyone know if I should get o-rings for the Jeep injectors or the Neon injectors? Or does it matter?

 

I put these on my 703s. And they fit just fine. I just tried entering in your XJ information in Autozone and it said that these don't fit but I'm sure they will since I'm assuming your 703s wont be different than mine.

Awesome, thanks for that 1996sportXJ. I'll pick those up tomorrow and hopefully put them on all SIX 703s.

 

No problem man. They come in packs of 4 so you'll need 3
