My Super Z is rolling over 50 hours so it's time to change the Hydro filter as per the manual. My question is, to those that have changed this filter, does the new filter have Excel Industries or Hustler's name on it? The filter I received from my dealer today is marked FPC Filtration Products Corporation Part number FPE30-25N. It is overwrapped in cellophane with the Hustler part number 783936 written in magic marker on it. Has my dealer given me a "generic" filter?
