A fuel manifold and fuel injector arrangement (54) comprises a plurality of fuel injectors (58) to supply fuel into the combustion chamber (15). Each fuel injector (58) has a main nozzle and a pilot nozzle. A main fuel manifold (60) is arranged to supply fuel to the main nozzle of each fuel injector (58) and a pilot fuel manifold (80) is arranged to supply fuel to the pilot nozzle of each fuel injector (58). The main fuel manifold (60) comprises a plurality of flexible main fuel pipes (66). The arrangement also comprises a plurality of cross-piece connectors (68) which comprise a stem (70) and four arms (72, 74, 76, 78). The stem (70) of each connector (68) is mounted on one of the fuel injectors (58). The first and third arms (72, 76) extend in opposite directions from the stem (70) and the second and fourth arms (74, 78) extend in opposite directions from the stem (70). Each fuel pipe (66) interconnects the first arm (72) of one connector (68) with a third arm (76) of an adjacent connector (68) and each connector (68) is arranged such that the first and third arms (72, 76) are arranged at an angle (± 2 ) relative to a plane (P 2 ) perpendicular to the axis (X) of the annular combustion chamber casing (56) such that the main fuel manifold (60) extends around the combustion chamber casing (56) sinusoidally. |
