1. A fuel assembly for a gas turbine engine, the fuel assembly comprising:
a first case extending circumferentially about an axial centerline, the first case extending from a first axial end of the first case to a second axial end of the first case;
a second case extending circumferentially about the axial centerline, the second case extending from a first axial end of the second case to a second axial end of the second case, the first axial end of the second case mounted to the second axial end of the first case;
a flow divider valve mounted on and to the first case;
a fuel supply tube connected to the flow divider valve;
a fuel manifold adapter mounted to the second case, the fuel manifold adapter including a first mount portion and a second mount portion, the first mount portion is rotatably mounted to the second mount portion, the first mount portion connected to the fuel supply tube, the second mount portion connected to the second case, the first mount portion axially moveable relative to the second mount portion by rotation of the first mount portion relative to the second mount portion; and
a fuel manifold extending circumferentially about the axial centerline, the fuel manifold is mounted on and to the second case, and the fuel manifold is connected to the first mount portion;
wherein the fuel manifold is located axially between the fuel manifold adapter and the flow divider valve;
wherein the first mount portion includes a first fastener;
wherein the second mount portion includes a second fastener;
wherein the fuel manifold adapter includes a link including a link body, the link body rotatably mounted to each of the first fastener and the second fastener; and
wherein the link includes a first bearing and a second bearing, each of the first bearing and the second bearing mounted within the link body, the first bearing surrounding the first fastener, the second bearing surrounding the second fastener.
