fuel systems on 5.0

what types of fuel systems came with the 5.0 mustangs im lookin at the early 90s models and how do i tell which one is in which car.. also which one is the best

all early 90's are the same, the all multi-port fi with mass air and map sensors, i think they have 155 lph pumps and 19 lbs.hr injectors

Actually the common fuel pump flowed only 110lph i believe. It is also a return style fuel system.
