Abstract
A fuel manifold (10) configured to form a base support structure (12) to support a plurality of fuel nozzles (14) including a pilot fuel nozzle is provided. A restraining element (30) is arranged in the base support structure (12) to support the pilot fuel nozzle. Restraining element (30) is integrally formed with the base support structure. The restraining element being integrally formed with the base support structure is effective to arrange for an incremental thickness (34) in a portion (39) of a wall (34) interposed between the inner diameter (36) of restraining element (30) and respective proximate edges (40) of a number of pilot bolt holes (32) disposed around the restraining element.
