I purchased a used Kubota ZD331 with a 72 inch mowing deck. It had seen some hard times which took a lot of work to fix. Now I am trying to replace the fuel filters. However, it appears the previous owner may have modified that system. Per Kubota, there should have been two paper filters to replace under the seat. However, mine does not appear to have those but instead has a glass site type holder with a metal mesh internal filter. The mount looks stock so if it was put in afterward, they made it look stock. Please see the pictures below. There are no brand name markings on either the holder or the filter and I am having trouble identifying it. Until I do, I can't replace it. Wondering if anyone recognizes it so I can replace it. Alternatively, if it is a metal mesh filter, does it need to be replaced or just cleaned and put back in?
