On my MFI track car, I used a Walbro generic pump, about $120, when my fuel pump died. I believe I used the 190 LPH (liter per hour) model. The MFI fuel circuit has a return line with a fuel pressure "regulator" (just a check valve actually), so any pump that will tolerate 1 bar fuel pressure and deliver enough fuel will work. One change is that the Walbro (and most other pumps) don't have the third port on them for over-pressure protection of the pump itself. You can plug that fuel line in your car if you use a 2 port pump. I believe modern high pressure pumps have internal pressure relief circuits for over-pressure protection. I have had no issues with that setup for several track seasons.
