As stated in other posts, and in this one as well. There were three things that happened on the fuel system. The first being the small tank inside of the left frame. These tanks were replaced in house, and should all be up to date. For those that were sold, there was a campaign that the dealer was resonsible for getting the units and repairing them. All units have been updated....every one, Kubota has a listing of every tractor that had the older tank. The second problem with the BX series was the actual fuel sending unit. The float valve was angled wrong, and it would show in an inaccurate amount of fuel. These have also been taken care of by Kubota. The third and hopefully the last, were some tanks where the sender sits in the tank had too large of an opening. The sender would not sit snug in the tank. Prior to making the kit, tanks were replaced with a new tank. The new kit is out now, and it comes with a different seal, and some kidney shaped brackets that curl inside of the tank, and then are tightened on the seal to assure a tight fit. All of the things have been posted, and all have been corrected. Kubota has fixed all the problems, and are no longer shipping units with these problems.
