21. A method of forming an earth-boring tool, the method comprising:
disposing a fluid port manifold within an opening of a body of the earth-boring tool, the opening extending from an outer surface of the body to a primary fluid passage;
disposing at least one fluid port sleeve within at least one fluid port, the at least one fluid port extending through a blade of the body to an opening in the fluid port manifold, the at least one fluid port located proximate to a cutting edge of the blade, and the blade comprising a plurality of cutting elements;
coupling the fluid port manifold and the at least one fluid port sleeve to the body of the earth-boring tool, a plurality of openings along a longitudinal length of the fluid port manifold providing fluid communication between the at least one fluid port and the primary fluid passage, the at least one fluid port sleeve extending into a corresponding opening of the plurality of openings of the fluid port manifold; and
disposing at least one nozzle within the at least one fluid port, adjacent the at least one fluid port sleeve.
