Many generic / off brand pumps "look" like the brand name pumps above, but since they were cheap china pumps the parts are not identical. Further, the engine or motor brand has nothing to due with the pump mounted to it as far as identification. Honda engines are used on the quality pumps like Koshin, AMT and Pacer but they are also used on the cheap clones.
