1. A fluid manifold apparatus, comprising: (a) an array of spaced-apart manifold fittings, where each manifold fitting comprises: (i) a generally tubular neck;(ii) a pair of spaced-apart generally tubular arms extending away from a first end of the neck such that the arms and neck collectively define a Y-shape; and(iii) a coupling connected to a second end of the neck, wherein the neck and the arms are rotatable as a unit relative to the coupling, wherein each of the couplings is connected to a fuel nozzle inlet stem of a fuel nozzle that is mounted to a combustor of a gas turbine engine; and(b) a plurality of curved tubes, each tube being coupled to one arm of each of two adjacent manifold fittings. 2. The apparatus of claim 1 wherein the coupling comprises an inner member and a collar surrounding the inner member. 3. The apparatus of claim 2 wherein the collar is threaded and includes an annular flange which bears against a shoulder of the inner member. 4. The apparatus of claim 1 wherein each inlet stem includes an inlet fitting which includes: (a) a ball-nose having a shape complementary to a seat defined by the inner member of the coupling; and(b) a resilient sealing element disposed in a groove in an outer surface of the inlet fitting. 5. The apparatus of claim 1 wherein each tube has a constant radius of curvature. 6. The apparatus of claim 1 wherein the ends of the tubes are rigidly coupled to the arms of the manifold fittings.
