So on my Jeep, when the replacement 4.0 showed up without fuel injection, I am thinking the PPO just bolted on a 258 manifold with a weber carb. Would it have as simple as that?

Yep, thats it. Manifold and the other stuff and you will be running a MPFI.

Yep you just need everything thing I have to convert back to FI plus figuring out the wiring. hopefully it has the 4.0 flywheel so you wont have to pull the motor that should be easy to check.
