Fuel pump options:
Use the stock pump for the 6.0. This is the route I'm going to try to do with mine. I have the fuel pump moduel from my engine donor.
Use a late style TJ fuel pump, which I believe is the 04-06, they upped the fuel pressure in the last couple years to 59 psi which is correct for the 6.0.
Use an external pump, like the E8248. Puts out twice the volume and higher pressure than the E2000s.
