Fuel containment structure for engine fuel delivery system

An engine system, comprising:

• an engine core including a flowpath, a compressor section, a combustor section, a turbine section and an engine case, the flowpath extending through the compressor section, the combustor section and the turbine section from an inlet into the flowpath to an exhaust from the flowpath, and the engine case housing at least a portion of the combustor section;
• a fuel containment structure including a first endwall, a second endwall and a sidewall extending axially along the engine case between the first endwall and the second endwall, the first endwall projecting radially inward from the sidewall to the engine case, the first endwall mechanically fastened to the engine case, and the second endwall projecting radially inward from the sidewall to the engine case;
• a fuel containment plenum formed by and extending between the first endwall and the second endwall, and the fuel containment plenum formed by and extending between the engine case and the sidewall;
• and
• a fuel delivery system configured to direct fuel into a combustion chamber within the combustor section, the fuel delivery system comprising a plurality of components arranged within the fuel containment plenum.
