I know most guys run a AFPR when running a 255lph fuel pump. Is the regulator necessary when running a low pressure 255lph pump, or can i get away with the stock fpr for now?

See, im going to be running a 14b soon, but planning on going way bigger in the future. I'd like to get the supporting mods done and push the 14b as far as i can until getting the BIG turbo, so a new fuel pump is on the list of mods for this summer, but im just curious, do i need a regulator to go with a low pressure pump, or would i just be safer getting the high pressure pump and the afpr?
 
You can "get away with" the stock FPR regarless but your fule trims will be messed up and your car will run rich.

For any 255 you need an AFPR.
