I know you're an EFI guy and I'm just a hobbiest, so please explain how this is any different than running the regulator off the back side of the rails. Any bubbles still go through the rails first, right past (and into) the injectors. Even if regulated on the inlet side of the rails there's just as much of a chance for bubbles getting past. With the regulator at the rear you don't have the hot fuel running back to the tank, aggravating the fuel bubble issue with the higher fuel temps. You're still bypassing fuel, and possibly bubbles, just at the rear of the car. Guarantee fuel temps in the tank and at the pump are lower than any system that bypasses from the engine compartment.
GM bypasses from the rear filter also, seems to be a non-issue for them. You probably won't get me to change what's worked for me for many years, the last ten years all forced induction builds. But I would like to know the theory or reasons why my way isn't good, because I definitely don't know everything, or even close. I'd appreciate your professional opinion.
