That's far different than conventional returnless designs.

The conventional design does fuel pump control via closed loop with a fuel

This is how Ford does it.

The way you prime a rail is to hold the injectors open and pump until you see
pressure.

Those who would give up essential liberty to purchase a little temporary safety
deserve neither liberty or safety. Nor, are they likely to end up with either.
