A fuel supply system for a gas turbine combustor includes an annular duct that at least partially defines a hot gas path within the combustor. An orifice is at least partially defined by the annular duct and defines a flow path through the annular duct into the hot gas path. A plurality of fuel injectors are arranged circumferentially around the annular duct to provide for fluid communication through the annular duct into the hot gas path. A fuel distribution manifold is disposed adjacent to an outer side of the annular duct. The fuel distribution manifold includes a main body that at least partially defines an inlet for receiving fuel, an outlet that is in fluid communication with the fuel injectors, and a fuel purge passage that provides for fluid communication between the inlet and the orifice.
