The FI system requires a low pressure pump. You can swap fuel tanks with a newer or four banger YJ that has the fuel pump in the tank.
You can get an external pump but you will need a pressure regulator for it also.
Hope that helps.

I am running a 360 with FI in my 90 YJ and this is the setup I used.

Fram G2 filter between the tank and pump.
Airtex E2000 external fuel pump
FF832 fuel filter after pump (this filter has a built in pressure regulator and return line for the returnless injection setups)

All these parts are over the counter and together will cost about $130 bucks.
Make sure you swap out any soft line for high pressure soft line.
