A fuel injector for a multipoint injection system can include a body defining an air cavity for allowing air to flow therethrough and an interior cavity. A fuel is tube disposed at least partially within the interior cavity of the body. The fuel tube can include a first end configured to connect to a fuel injector connector of a fuel manifold, and a second end configured to connect to a fuel distributor of the fuel injector, wherein the fuel injector is configured to be disposed at least partially in a combustor dome. The fuel tube is configured to move in an axial direction to allow flexibility between the fuel manifold and the combustor dome. 1. A fuel injector for a multipoint injection system , comprising:a body defining an air cavity for allowing air to flow therethrough and an interior cavity;a fuel tube disposed at least partially within the interior cavity of the body, wherein the fuel tube includes a first end configured to connect to a fuel injector connector of a fuel manifold, and a second end configured to connect to a fuel distributor of the fuel injector, wherein the fuel injector is configured to be disposed at least partially in a combustor dome, andwherein the fuel tube is configured to move in an axial direction to allow flexibility between the fuel manifold and the combustor dome.2. The injector of claim 1 , wherein the fuel tube is a coiled fuel tube.3. The injector of claim 2 , wherein the coiled fuel tube is configured to axially compress and/or expand between the first end and the second end.4. The injector of claim 2 , wherein the coiled tube is contained within the interior cavity.5. The injector of claim 4 , wherein the body is formed from an outer heat shield and an inner heat shield disposed within the outer heat shield.6. The injector of claim 5 , wherein the outer heat shield and the inner heat shield are integrally formed together claim 5 , wherein the inner heat shield at least partially defines the air cavity.7. The injector of ...
