Pressure regulator on second pump?

I have my oem pump on a boost a pump and just installed a ECS Stage 1 addon pump that has the bulkhead on the side of the tank and also feeds into the same oem line but only kicks on at about 5 psi. I was told that with my returnless setup (04 Supercharged C5), that the fuel pressure would spike due to the second pump not having a pressure regulator...r

What if I use an oem style GM filter / retun regulator combo on the second pump or even just an aftermarket regulator (the bulkhead has a return port thats capped btw)? Will this stabilize the fuel pressure during tuning?

* I do plan to do a full upgrade in the summer though and drop the tanks, etc...
