Zusammenfassung:	A fuel nozzle assembly (10) is presented for a gas turbine engine (12). The fuel nozzle assembly (10) includes a rocket unit (14) and a swirler (16) with an aft end (18) in threaded engagement with a forward end (20) of the rocket unit (14). The fuel nozzle assembly (10) may include an oil tip (36) including a clocking feature with a mechanical constraint to orient the oil tip (36) at a predetermined angular orientation (42) relative to the swirler (16). The fuel nozzle assembly (10) may include one or more gas stage inlets (13, 15), one or more oil stage inlets (17, 19), and a flexible hose (26) to direct the oil to a plurality of rocket units (14).
