I have a 401 b John Deere tractor that I would guess to have a cracked fuel filter. It is the one that is round and only leaks when running. I went to jd parts.com and can not find what I need is it because it is a industrial model. What ag tractor do I need to look up that would have the same one. I called my local green dealer and they said they could and would not help me find it.it is a industrial model. I guess I just need the right part number and then go back and try again. The yellow house was not much help either they wanted me to bring the tractor to them and they would fix it I said no. Any help would be thankful.
