I recently bought a used Snapper LT300 that has a 22HP Briggs Professional. Quiet and smooth motor. I am wanting to change the oil and put a new filter on it. It has a yellow filter that says 020612FF which is about 2 inches long. I have enough room to put a 6 inch long filter if I could get proper cross reference. Trying to find out what options I might have. Any ideas how to find this?
