FPR is AFTER the injectors/rails. AFTER.

The pump flows fuel from the tank to the FPR. The pressure is maintained from the pump to the FPR, in between which sit the injectors. Any excess pressure over what the FPR is set for is relieved into the return line which goes back to the tank.

I just wanted to reclarify what has already been said.
