It seems to be a far from one cause problem from what i've read with some saying its the heat & various other reasons ..be interesting what others have to say & if they've found a 'cure' .

The U.S. Energy Information Administration (EIA) estimates that in 2020, the 123.49 billion gallons of finished motor gasoline consumed in the United States contained about 12.63 billion gallons of fuel ethanol, so about 10%.
It's the grade of material used that's the problem, Ascerbis made a range of tanks in the 'wrong' material as used by Ducatiand probably HD has some too
