I have a 1999 ZX185c I added a florite pumpout to it last year, it works ok, but seems my pump is kind of weak. I am wanting to add a stronger pump. Does anyone know what kind of pumps come in skeeters, and if it will be the type that I could just change the cartrige. I have not removed the gas tank yet, so I cant see them very well. This is on my list of things to do this winter, so I am just looking for some helpfull input.
