The engine core includes an engine housing structure which houses a compressor section, a combustor section and a turbine section. The fuel containment structure is outboard of and connected to the engine housing structure. The fuel containment plenum is formed by and located between the fuel containment structure and the engine housing structure. The fuel delivery system includes a plurality of fuel injectors, a fuel supply line and a fuel manifold fluidly coupling the fuel supply line to the plurality of fuel injectors. The fuel manifold is arranged within the fuel containment plenum. The plenum purge circuit is configured to purge fuel, when leaked into the fuel containment plenum from the fuel delivery system, out of the fuel containment plenum.
