WHEREAS, Vehicle Code Section 27156 and Title 13 California Code of

the prohibitions of Vehicle Code Section 27156 for the Fuel Enhancer.

WHEREAS,   pursuant to the authority vested in the Executive Officer by Health
and Safety Code Section 39515 and in the Chief, Mobile Source Division by
Health and Safety Code Section 39516 and Executive Order G—45—5, the Air

     1.    The Fuel Enhancer is an add—on device that is attached to the fuel

     2.    The fuel line is part of the required motor vehicle pollution
           control system.

     3.    The Fuel Enhancer is intended for use with a required pollution

           original design of a motor vehicle pollution control system.

           Vehicle Code Section 27156 and an add—on part as defined by 13 CCR
           Section 1900(b)(1).

     6.    The Fuel Enbancer does not reduce the effectiveness of any
           required motor vehicle pollution control device.

    7.     The ARB, in the exercise of technical judgement, is aware of no
           basis on which the Fuel Enhancer will provide either a decrease in
           emission or an increase in fuel economy.

    8.     It has not been determined what effect use of the Fuel
           Enhancer may have on any warranty, either expressed or implied, by
           the manufacturer of a motor vehicle on which the device is
