Perfect Fit
This kit worked perfectly with my discontinued 258 pump. I learned that the pump should be completely removed to adequately reinstall the diaphragm. Two "sealer washers" were included in the kit. Since my pump had no such washers on it, I am not sure what their purpose is. I called the company and was directed to the appropriate department. There I reached a voice mail - a Mr. Smith. I left a message, but I have never had a return call.
