I used a fuel pump or the same year 4 banger. The 4 banger has FI with a intank pump. It is pretty much a straight swap.
If you have an intank pump already then just run the line from the tank to a return style fuel filter and hook up the return side of the filter to the return line. The pressure is not an issue because of the return.
The OP was not asking i anybody else would do this rather can HE do the swap and the answer is yes.

yup, he wasn't asking what ya'll would do. and if you want to run a lower pressure pump, you can order a basic holley from any auto parts store (and its probably in stock) for about 100 bucks. thats what i run on my 87 with a two barrel holley

NAPA sells an electric fuel pump that works perfect, under $30.

I had problems running an external pump. I couldn't mount the pump low enough and the uel kept draining back to the tank and the pump was not strong enough to pull the fuel back up. Most electric pumps are designed to push fuel not pull it. I have been using the intank pump for about 8 months and the pressure is not an issue because of the return style filter.
I would just wire the pump to a source that is live with the ignition on and wire it through a oil pressure switch for safety.
The intank pump really is the best option IMHO.

i used a check valve to stop the fuel from draining back and have my pump in the engine bay, by the cruise control unit

This is a good way to do it.

Also, an elect pump on the frame rail will always be "wet" once primed, no way for it to drain back. Use it like you would a FI setup, and let the system prime for 5 sec before engaging the starter.

I had nothing but trouble and still maintain the stock in tank pump that he already has with a fuel return is the best way to go. Why re-engineer something he already has that works fine?

I for the life of me cannot see a justifiable reason to remove a fuel injection system in favor of a less powerful carbureted system... I would just stick my head in there and replace the fried wiring, but then again I love re-wiring stuff in the first place...

this is the most efficient way. i didn't have an in-tank pump so i had to do an external pump. and i couldn't mount it on the block like it should have been because my block is a 99 and doesn't have the spot any more to put a factory pump

I like it and have thought of doing the same thing. I did not think it was as simple as just replacing the distributor, intake, and bolting on a carb. I am old school and like to Keep It Simple Stupid (KISS).

That statment in this thread is kinda ironic.

You DO realize that you are telling this to a guy who is putting a CARB on his FI engine, right?
(apparently, because fixing it correctly was too hard)

@ matlock1983 -

It has nothing to do with "fixing it the right way." So in your mind, anything that isn't OEM doesn't belong on a Jeep? Do you drive a stock Jeep without any modifications? NASCAR has been removing EFI off stock cars for years and replacing them with carburetors.

I chose to modify my jeep to a level that I was comfortable working on. I appreciate all your assistance in answering the question of is this possible. Oh wait, you just piped in with a smart comment to show off your superiority to me when it comes to all things mechanical.
