Onan carburetor float has fuel inside of float

My 2015 Onan 5500 has the same problem, I called Cummins in Ohio and was told that no parts are available for that carb. Went through two local repair shops and they got the same answer. I sealed the float with Seal-all and its holding for now. I am now trying to find a carb that uses the same float but have had no luck yet. Ill be dammed if I'm going to spend 300 dollars to get a 6 dollar float. If any one has a float or has located one that works please share that info. Thanks.
