Aftermarket Alternative Fuel Vehicle (AFV) Conversion Requirements
All AFV conversions must meet current applicable U.S. Environmental Protection Agency or California Air Resources Board standards for aftermarket conversions. Aftermarket systems must be properly certified for the specific vehicle or engine family that is being converted. An aftermarket AFV conversion is defined as a conventional original equipment manufacturer vehicle altered to operate on propane, natural gas, methane, ethanol, or electricity.
