do away with carburetor

I would look for an aftermarket kit. You are going to need half a new truck to do this modification. The dash is different, as is the gas tank / fuel pump, all the under-hood wiring, and the sensors that will not mount to your engine.

The place to start is by reading through one of Chrysler's training manuals that describes how the system works, then stop back here with your list of dozens of questions. A friendly dealer might still have some of those training manuals in their employees break room, or some older mechanics might still have theirs. I have some to share too, but due to a major house fire, they are all packed away right now and I am not sure I can find them.
