On another forum I was told this:
As of January 1, 2009, all portable fuel containers sold in the United States are required that they must meet new federal regulations based on California’s CARB regulations (no evaporation leaks) and must meet the requirements of the new childproof features.
My question is about old fuel cans bought before Calif and now the American federal regs had CARB rules. Are the old cans legal to use and will not cause hassles if a state police officer sees them? In other words use is OK just illegal to sell?
