Anyone out there have or are familiar with the in tank hydraulic filter on a Carlton SP5014 stump grinder. Its an in tank filter, by myfiltre. (MFX1002A10HBP01. I have been trying to replace the element for sever months. I ordered one from the parts manual but the one I pulled out had a 6 sided star type connection to the intake that fit into a star type base in the tank. Tried Carlton, Filtre, the carlton distributer, Cannot track it down. Order several from compatible charts, but none fit. Any suggestions.
