A fuel manifold for distributing fuel to a gas turbine engine includes a plurality of interconnected manifold segments. Each manifold segment extends between a pair of fuel injector inlet fittings. Each manifold segment includes a fuel liner defining an internal fuel passage therethrough fluidly connecting a pair of fuel injector inlet fittings. A wire braid layer surrounds the fuel liner, a fire sleeve surrounds the wire braid layer, and a flexible thermal shield surrounds the fire sleeve. An insulation space is defined between the fire sleeve and the thermal shield to thermally isolate the fire sleeve from conditions external to the thermal shield.
