Do I Need A Fmu With A V-afc??

I AM GOING TO RUN DSM INJECTORS WITH A V-AFC2 THAT WILL BE HACKED..DO I NEED A FMU? OR CAN I JUST USE THE V-AFC WITH A BIGGER FUEL PUMP LIKE THE A 255 LPH PUMP AND A OTHER ? THERE ARE TWO VACCUM LINES ON THE TIAL WASTEGATE.WHERE DO THEY GO? I KNOW THAT ONE GOES TO A VACCUM SOURCE BUT WHICH ONE TOP OR BOTTOM???
