Abstract: The present invention provides a flexible hose for connecting a fuel manifold to a burner of a gas turbine engine. The flexible hose includes a metal convolute tube, an elongate member or members located in grooves formed in the inner surface of the convolute tube, and a pressure-containing sheath outside the convolute tube. The flexible tube has end connectors fluidly-tightly joined to respective ends of the hose for connection at one end of the hose to the fuel manifold of the gas turbine engine, and at the other end of the hose to the burner of the gas turbine engine.
