got a Stone hydraulic distribution setup and the pump’s acting up. is this KP31 kit meant to be a replacement for Stone pump assemblies?

For Stone branded hydraulic pump assemblies used in hydraulic distribution systems, the KP31 pump kit is intended as a replacement or service kit. It’s set up to let you service the pump as a kit instead of chasing individual pieces.
