I'm going to the junkyard tomorrow looking for injectors to put in my '91 Cherokee.
What vehicles should I look for that have injectors I can use in my '91 XJ. I'm gonna try to get two sets. A set for my current 4.0 with a few mods.(19lb) And another set for the stroker I'm building.(24lb or higher)
What should I be on the look out for? Any special tools I need to remove the injectors?
Thanks...

I wouldn't unless you want to send them off to get cleaned. Injectors that sit with fuel in them may end of stuck.

Agree. Might be a better idea to search in ebay instead.

I guess Ill just order some off eBay then.
Whats the highest flow injector I SHOULD go on a stock 4.0 with intake, throttle-body, and mild exhaust? From what I've read, is to either go with the neon 703's or the mustang #19's. If I read the forums correctly, I wont get more fuel with those 2 injectors but the atomization is much better.
Any thoughts on a fuel pressure regulator on a mainly stock 4.0? Is that something I should put on once I get new injectors?

If you are on a mildly moded 4.0, stock injectors should be more than fine. Unless you have indicators that you need more fuel.

On ebay, there's a seller named precisioninjectors. He sells rebuilt upgraded jeep injectors for a very reasonable price.

www.precisionautoinjectors.com. He also sells on ebay. I've used his injectors on three of my 4.0s and they work great. No guesswork.
