                                   EXECUTIVE ORDER D—559
                         Relating to Exemptions Under Section 27156
                                       Of the vehicle Code

                                      "FUEL STABILIZER®"

WHEREAS, Vehicle Code Sections 27156 and 38391, and Title 13, California Code of
Regulations (hereafter "CCR") Section 2222(e), authorize the California Air Resources Board
(ARB) and its Executive Officer to exempt add—on and modified aftermarket devices from the
prohibitions of Vehicle Code Section 27156.

WHEREAS, Dieselcraft of P.O. Box 7670, Auburn, CA 95604, has applied to the ARB for
exemption from the prohibitions in Vehicle Code Sections 27156 and 38391 for its Fuel
Stabilizer, Models 5—29 and 30—200, manufactured by Steel Craft Manufacturing, Inc. of 620
South 6°" Street, P.O. Box 169, Hopewell, Virginia 23860, for installation on 2003 and older
model—year diesel powered vehicles. Model 5—29 is for diesel engines with fuel flow rate
between 5 to 29 gallons per hour, and Model 30—200 is for diesel engines with fuel flow rate
of 30 to 200 gallons per hour.

WHEREAS, pursuant to the authority vested in the Executive Officer by Health and Safety
Code Section 39515 and in the Chief, Mobile Source Operations Division by Health and
Safety Code Section 39516 and Executive Order G—02—003, the ARB finds that:

1.     The Fuel Stabilizer is an add—on device installed in the fuel line of a motor vehicle.

2.     The Fuel Stabilizer is made of ferrite magnet, housed in a gold—anodized 6061 T6
       aluminum material.

3.     The fuel line is part of the required motor vehicle pollution control system. The Fuel
       Stabilizer by being installed in the fuel line constitutes a modification of the original
       configuration of the fuel line.

4.     The Fuel Stabilizer is a device subject to the prohibitions of Vehicle Code Section
       27156 and an add—on part as defined by Title 13, CCR Section 1900 (b)(1).

5.     The Fuel Stabilizer does not reduce the effectiveness of any required motor vehicle °
       pollution control system.

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

7.     The ARB has not determined what effect the use of the Fuel Stabilizer may have on
       any warranty, either expressed or implied, by the manufacturer of a motor vehicle on
       which the device is installed.


       The Fuel Stabilizer is not a certified motor vehicle pollution control device pursuant to
       Health and Safety Code Section 43644.

       The ARB by granting an exemption to Dieselcraft for the Fuel Stabilizer does not
       recommend or endorse in any way the device for emissions reduction, fuel economy,
       or any other purpose.

T IS HEREBY RESOLVED that Dieselcraft‘s Fuel Stabilizer is exempt from the prohibitions
of Vehicle Code Section 27156 for installation on 2003 and older model—year diesel powered
vehicles subject to the following conditions:

1.     No changes are permitted to the Fuel Stabilizer as described in the application for
       exemption. Any changes to the Fuel Stabilizer or any of its component, or other
       factors addressed in this order must be evaluated and approved by the ARB prior to
       marketing in California.

       Marketing of the Fuel Stabilizer without a permanent label showing the Executive
       Order number or marketing of the Fuel Stabilizer for an application other than the one
       stated in this Executive Order shall be prohibited unless prior approval is obtained
       from the ARB. Exemption of this product shall not be construed as an exemption to
       sell, offer for sale, or advertise any components of the Fuel Stabilizer as an individual

       Any oral or written references to this Executive Order or its content by Dieselcraft, its
       principals, agents, employees, distributors, dealers, or other representatives must
       include the disclaimer that the Executive Order or the exemption it provides is not an
       endorsement or approval of any emissions reduction claims for the Fuel Stabilizer, and
       is only a finding that the device is exempt from the prohibitions of Vehicle Code
       Section 27156.

       This exemption shall not apply to any device, apparatus, or mechanism advertised,
       offered for sale, sold with, or installed on a motor vehicle prior to or concurrent with
       transfer to an ultimate purchaser.

       No claim of any kind, such as "Approved by the Air Resources Board" may be made
       with respect to this Executive Order in any advertising or other oral or written



             Violation of any of the above conditions shall be grounds for revocation of this order. The
             order may be revoked only after ten day written notice of intention to revoke it, during which
             period the holder of the order may request in writing a hearing to contest the proposed
             revocation. If a hearing is requested, it shall be held within ten days of receipt of the request,
             and the order may not be revoked until a recommendation is made, after the hearing, that
             grounds for revocation exist.

             Executed at El Monte, California, this Z] 2 T day of April 2003.
