Should this help to diagnose such problems, the cutaway diagram of the
914 pressure regulator shows a straight frictionless shot straight to
the carbs. The relief valve sends excess pressure back through the
return line. Like the old style steam pressure cookers that noisily
popped off the steam. Pressure is essentially set by the float valve in
the carbs, since if a high enough fuel flow existed, the relief valve
would be closed and no nothing.
