Each swirl passages of the needle guide and fuel swirl member of a fuel injector has a longer and wider entrance portion and a shorter and narrower exit portion to allow only the latter portion, not the former portion, to perform a metering function. Production of swirl passages is facilitated and more consistent metering results.
