I have an older softener system that is now leaking from the cylinder/cylinder seals. I believe it is a Fleck 2510, but there are no descriptive markings on it that says that. The only markings are: SN: 193360-001.000-0002C00 and P/N 40278. Can anyone out there look at this info and the pictures and let me know what I have, as I need to order new cylinder seals and I want to order the correct ones. Thanks.
