I have an exmark 26hp efi. I'm looking for a aftermarket replacement hydro filter. If any one had any numbers so I can go to my local auto parts store that would be great. I know a new filter is about $25 and the dealer is about 20min away, parts store is 2 min. away. My parts store as no books to cross reference filter numbers. I appreciate and advice. I need to replace it tomorrow morning.
