A method for assembling a fuel injection assembly for use in a turbine engine is provided. The method includes providing a cap assembly that has at least one first opening extending at least partially through it and a plurality of second openings extending at least partially through it. Moreover, a plurality of tube assemblies are coupled within the cap assembly. Each tube assembly includes a plurality of tubes. Further, at least one injection system is coupled to the cap assembly to enable a fluid from a fluid source to be discharged through at least one of the plurality of second openings. The fluid flows between at least two adjacent tube assemblies to facilitate at least one of reducing a temperature within the cap assembly and reducing dynamic pressure oscillations within a combustor during operation of the turbine engine.
