inline fuel pump vs in-tank fuel pump

[TSi92]

I keep hearing people say that upgrading the in-tank fuel pump is not all that necessary. That with a good in-line pump and a AFPR you will have all the fuel you need (even with small injectors). I ask because I have a denso 70 gph in-tank pump right now, and I'm FWD so it's a real pain to change it, plus some of my screw heads are rounded off so it's gonna be a real pain to take those out. I have 720's and a boost-a-pump laying around. Do you guys think I still need at least a 255 or tt supra pump?

Are you running all those mods listed in your profile with a stock fuel pump???

No I have an upgraded denso pump that flows 70 gph (the one derby sells). Right now it's not rewired but that's because I have that boost-a-pump laying around. I heard that thing will boost my voltage to about 14 volts to the pump.
