We avoided the fuel cell for complexity and weight reasons.

I would be consulting PTuning about the fuel cell setup. Weight reasons? That's kinda confusing since a fuel cell weighs less. I don't scrimp on things though..

The purpose of the rising rate fuel pressure regulator is primarily used to keep a consistent fuel pressure and raise the pressure linear to boost. You should relate your injector size to estimated whp, not rely on bumping up the fuel pressure because that is secondary and considered a fine adjustment.

Fuel pressure does have it's advantages to an extent as well. Higher pressures allows some injectors (EV6 and newer) to atomize the fuel unbelievably. So running persay 55-65 PSI of pressure on a certain injector may yield more beneficial to the atomization properties alone compared to injector B (larger at a lower fuel pressure) in helping det.

100%. TONS of potential for failure and utter chaos if not done properly on several different levels.

I'm pretty sure mecanica pito is running dual intake walbro pumps. Not sure about his line size of rail but the GE came out after he did his setup I believe.
