                               EXECUTIVE ORDER D—534

                               Relating to Exemptions under
                            Section 27156 of the Vehicle Code

                               Liberty Motor Company, Inc.
                            Replacement Fuel Tank Systems

Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 of
the Vehicle Code; and

Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the
Health and Safety Code and Executive Order G—45—9;

IT IS ORDERED AND RESOLVED: That installation of replacement fuel tank systems,
manufactured by Liberty Motor Company, Inc. of 2390 S. Service Road W., Oakville,
Ontario, Canada L6L 5M9, has been found not to reduce the effectiveness of the applicable
vehicle pollution control system, and therefore, the replacement fuel tank systems are
exempt from the prohibitions of Section 27156 of the Vehicle Code for installation on 1996
through 2000 model—year Ford Motor Company 3.0 and 3.8 liter gasoline Windstar
minivans, originally equipped with a 20— or a 26—gallon plastic fuel tank.

This exemption is based on the 2—day diurnal evaporative emission test and On—Board
Diagnostic II (OBD I1) system test conducted by Technessen Ltd. (formerly Liberty‘s
parent company). The test data showed that evaporative emissions of a 1998 Windstar
modified with the fuel tank system were below the applicable standard. Technessen
also showed that the fuel tank system did not affect the operation of the vehicle‘s OBD II
leak detection system. The same evaporative emission and OBD II system impact is
expected when the fuel tank systems are used on any of the vehicles included in the

Exemption of the replacement fuel tank systems shall not be construed as an exemption to
sell, offer for sale, or advertise any component of the replacement fuel tank systems as
individual devices.

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

This Executive Order is valid provided that installation instructions for the replacement
fuel tank systems do not recommend tuning the vehicle to specifications different from
those of the vehicle manufacturer.

Changes made to the design or operating conditions of the replacement fuel tank
systems, as exempt by the ARB, which adversely affect the performance of the
vehicle‘s pollution control system shall invalidate this Executive Order.


Marketing of the replacement fuel tank systems using an identification other than that
shown in this Executive Order or for an application other than those listed in this
Executive Order shall be prohibited unless prior approval is obtained from the ARB.

In addition to the foregoing, the ARB reserves the right in the future to review this
Executive Order and the exemption provided herein to assure that the exempted add—on
or modified part continues to meet the standards and procedures of Title 13, California
Code of Regulations, Section 2222 et seq.

This Executive Order does not constitute any opinion as to the effect the use of the
replacement fuel tank systems may have on any warranty either expressed or implied
by the vehicle manufacturer.

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


Violation of any of the above conditions shall be grounds for revocation of this Executive
Order. The Executive Order may be revoked only after a ten—day written notice of
intention to revoke the Executive Order, in which period the holder of the Executive
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 Executive
Order may not be revoked until a determination is made after a hearing that grounds for
revocation exist.

Executed at El Monte, California, this _# 1#       day of March 2002.

                                       Allen J:/;ons, Chief

                                           EVALUATION SUMMARY

           Manufacturer Name: Liberty Motor Company, Inc.

           Name of Device: Replacement Fuel Tank Systems

                 Liberty Motor Company, Inc. (Liberty) of 2390 S. Service Road W., Oakville,
           Ontario, Canada L6L 5M9 has applied for transfer of Vehicle Code 27156 exemption
           Executive Orders D—491 and D—491—1. The exemptions were issued to Technessen Ltd.
           for its replacement fuel tank systems used on 1995—2000 model—year Ford Motor
           Company gasoline Windstar minivans. Since the issuance of these exemptions,
           Technessen has ceased operation, and Liberty, which had been operating under
           Technessen, is now operating as an independent entity and is the authorized marketer
           of the replacement fuel tank systems. As a result, Liberty has requested transfer of the
           existing exemptions to Liberty. In addition, Liberty has requested a change to the fuel
           tank system design.

                 Grant exemption to Liberty as requested and issue Executive Order D—534.

           Device Description:
                  Liberty‘s replacement fuel tank systems allow lowering of the van floor for wheel
           chair access. The lowered floor extends approximately 90 inches forward from the rear
           bumper. This modification requires replacement and re—location of the stock fuel tank
           from the original mid—ship location to just in front of the lowered floor. In the
           modification, the stock high—density polyethylene (HDPE) plastic fuel tank is replaced
           with Liberty‘s 20—gallon 16—gauge stainless steel fuel tank. The stock emission
           canister(s) is retained but moved forward, adjacent to the fuel tank. The fuel system
           includes extension fuel and vapor lines (high pressure/low permeation SAE 30R9 lines
           and SAE 30R7 lines). The rollover and emission control valves are replaced with Ford
           parts. The stock fuel pump/sending unit, filler tube, and gas cap are retained and/or
           replaced with Ford parts.                                                     '
                  D—534 covers the following systems and vehicles:
                  (1) 1999—2000 Ford Windstars, originally equipped with a 26—gallon HDPE fuel
                        tank. This is a transfer of D—491—1. Liberty replaces the stock tank with its
                        20—gallon steel tank. The stock fuel pump/sending unit is retained in the
                  (2) —1996—1998 Ford Windstars that meet California‘s emission standards and
                        On—Board Diagnostic II (OBD i1) system requirements, including federal and
                        Canadian Windstars. This is essentially a transfer of D—491 with one
                        change. D—491 exempted a system that re—uses the stock 20—gallon HDPE
                        tank. Liberty no longer offers this system. Instead, Liberty will be replacing
                        the stock tank with its steel tank. The change covered under D—534 is the
                        replacement of the stock tank with Liberty‘s 20—gallion 16—gauge stainless
                        steel tank. This is the same system used in Liberty‘s 1999—2000 system.
                        To allow correct mounting and fitting, the stock fue!l pump/sending units on
                        the 1996—1998 Windstars are replaced with Ford‘s 1999—2000 fue!
                        pump/sending unit.

Liberty‘s fuel tanks are fabricated by Sidhu Metals and Robica Manufacturing Ltd. of
Ontario, Canada. The van conversions are performed by Liberty, Creative Carriage
Ltd., and Advance Star of Ontario, Canada.

Discussion/Basis for the Recommendation:
       Exemption under Executive Order D—491 was based on the 2—day diurnal
evaporative emission test and OBD 11 system test results submitted by Technessen.
Testing showed that a 1998 model—year 3.8 liter Windstar modified with Technessen‘s
fuel tank system (system re—used the stock tank) did not exceed the applicable 2—day
diurnal emission standard. It also showed that the fuel system did not have any
adverse impact on the vehicle‘s OBD II system (0.040—inch diameter leak). Based on
engineering evaluation of the design changes (replacement of the stock tank with steel
tank) and carry—over of Technessen‘s 1998 test data, Executive Order D—491—1 was
issued, exempting the system for use on 1999—2000 Windstars. Liberty will essentially
be marketing the same systems exempted under D—491 and D—491—1. Therefore, the
exemptions are transferred and extended to Liberty as requested.
