I've been researching fuel injectors for a couple hours and can't seem to come up with a definitive answer of what I need; there is a lot of conflicting information out there.

As far as I can reason, ordering Bosch 0280155710 injectors in combination with a Bosch/Chrysler 4418850 fuel pressure regulator will be a bolt-in modification for my 4.0 HO*. All I need is for someone to confirm or deny that.

I've sourced the parts I need and also the different parts I've seen others suggest in various threads all over Jeep forums, and done my best to find the answer on my own; I'm leery of purchasing without confirmation, however, and I can't find that. Any help is appreciated!

*Note: Supposedly the increased fuel pressure from the regulator and higher PSI injectors helps the H.O. motor and is a suggested swap. This is why Bosch 710s are recommended for pre-95 Cherokees while the majority of XJ owners go with something else, hence a lot of conflicting info.

 

Two options....

 

All you need right there ^^^

 

^^^^^^ yep. 703s.

 

And the crowd roars x3

 

Thanks folks. I had been trusting that chart more than anything else I saw during research. I'm going to go with Option 2, and I'll make sure to update on how it works out!

 

How did it work out?
