plastic fuel tanks can be made ethanol-tolerant
I have a 2002 Triumph Speed Triple with 19K miles and a rotomolded plastic fuel tank. No deformation problems. It is fueled from the same sources as my Paul Smart 1000, which has bulging-tank syndrome.
This tells me it is possible to formulate an ethanol-tolerant polymer and make durable fuel tanks with it. But Ducati/Acerbis didn't do it.
