HOLLEY Model 2300 2-Barrel: Overhaul: Disassembly

From fuel bowl, remove float, spring, baffle, lock nut and screw, and fuel inlet seat and valve (seat and valve need not be disassembled further). Remove pump diaphragm cover, diaphragm assembly and return spring. If necessary to remove accelerator pump synthetic valve, grasp it firmly and pull it out. If valve tip should break, be sure that it is removed from fuel bowl before reassembly.
