Find a Kohler dealer and have them look it up. The dealer I went to and asked about it said there was an entire part # for the kit, but they couldn't seem to locate it. They looked it up in two or three groups, I guess the bracket, the filter assembly and the hose and elbow. They came up with a price under $200. I guess if the Kohler dealer doesn't understand what you are trying to do, tell him to show you a diagram of the 26 FI engine.
