wrong. acetone will eat some rubber and plastics and composites, but fuel systems must be engineered to stand up to solvents. gasoline eats plastics and rubbers and composites too, but you don't use those types of materials in a fuel system
Acetone as a solvent makes gasoline look like a noble gas. Acetone will dissolve stuff in minutes that gasoline could sit in for years. It's particularly good at dissolving oils, including the oil that lubricates the walls of your cylindars.
