A fuel injector (10) for supplying fuel to a fuel consuming devise (12) includes a fuel inlet (16) for receiving the fuel, a nozzle tip (18) for dispensing the fuel from the fuel injector (10), a conduit (20) for communicating the fuel from the fuel inlet (16) to the nozzle tip (18), a valve seat, and a valve selectively seatable and unseatable with the valve seat for selectively preventing and permitting fuel flow out of the nozzle tip (18). The nozzle tip (18) includes a non-circular recess on a downstream side thereof and a metering hole on an upstream side thereof opening into the non-circular recess to allow fuel to exit the nozzle tip (18), the metering hole having a smaller area than the non-circular recess.
