Some reviews I read and on television ads they mentioned that as long as the device fit over the gas fill that it would work. What it does is allow air to escape but not let the gas splash out. It controls the venting thus allowing for a more complete fill. Although specifically made for motorcycles I see no reason why it wouldn't work on many other things....such as lawn mowers, 4-wheelers, jet skis and such. If you need specific applications I would either email them or call, they are very easy to talk too and will not pull your leg...;)
