Disclosed in this description are modifications either attached to, or made as part of, accelerator pump discharge nozzles, tubes or pipes. These modifications include the use of a fuel atomizer plate for carburetors as either a separate device placed beneath or on top of an accelerator pump discharge nozzle, tube or pipe, or simply located in the fuel stream of an accelerator pump discharge nozzle, tube or pipe, or a fuel atomizer plate for carburetors made as a single unit along with an accelerator pump discharge nozzle, tube or pipe. All are used on standard engines and assist in the atomization and homogenization of incoming fuel with incoming air to improve engine performance
