This one looks like it goes in line. Which could take some modification with the hard plastic jeep lines. And what would you do with the regulator on the rail? I'm looking at some cheap bosch injectors right now, and I know to make them work best you need to bump up the pressure a few pounds.

Also, read this post on 4bangerjp for some injector info,

Chrysler/Jeep and FoMoCo Fuel Injectors

I personally would not bother with an adjustable pressure regulator especially for the 2.5l. Not so sure that computer is flexible enough in its programming to know what to do with all that extra gas. IMHO

Thanks. I had read that write up on injectors before, and was looking for it last night but couldn't find it . I go to 4banger often as I have a 2.5L. Thanks for the link it was exactly what I was looking for. I've heard if I go with the #19lb injectors I should bump up the fuel pressure a couple pounds, so I'm looking into it. I've got the 4.0 TB and I have headers and hi-flo exhaust waiting to go on soon.

Good luck with whatever you decide to do with the injector swap. Please post any results you have, good or bad. I should mention that I spoke with Bocsh and was told that they never made a 4 hole injector for the Jeep 2.5l. He could not provide a model, from another engine, that would work but he lead me to believe that if I provided him a model number of an injector he could see if it would work in the Jeep 2.5l.

I have been leaning towards trying a 19lb injector, which one I don't know because it is not a major concern yet.
