All the one's I've seen have a little valve in the middle there. It's for holding system pressure from the draining back to the fuel tank through the WUR's control pressure return line when shutting off the motor.
Without it system pressure would immediately drop to zero when shutting off the motor and fuel pumps and it's not supposed to do that. System pressure should hold around 35psi at least overnight..
