Looking at swapping out the stock injectors for the 704 multi port ones. My question is do I need a pressure regulator or can I just swap them out? Wanted to swap them out when I do the intake swap. Also does the 99/00 jeeps have the 704 injectors? Was gonna hit up a jy and try to find the intake and figured would grab the injectors should they still be in the jeep.

Forgot - 94 XJ 4.0 6cyl - all stock engine
