IT IS ORDERED AND RESOLVED: That the installation of the "Cagle Mark 1I
Automatic Fuel Control" device manufactured by Cagle Corporation, 2667 East
28th Street, Suite §17, Long Beach, California 90806 has been found not to

by gasoline with conventional carburetors and mechanical or electric fus1
pumps with and without recirculation systems.

This Executive Order is valid provided that installation instructions for
this device will not recommend tuning the vehicle to specifications
different from those submitted by the device manufacturer.

Changes made to the design or operating conditions of the device, as
exempted by the Air Resources Board, that adversely affect the performance
of a vehicle‘s pollution control system shall invalidate this Executive
Order.

Marketing of this device using an identification other than that shown in
this Executive Order or marketing of this device for an application other
than those listed in this Executive Order shall be prohibited unless prior
approval is obtained from the Air Resources Board.   Exemption of a kit shall
not be construed as an exemption to sell, offer for sale or advertise any
component of a kit as an individual device.

This Executive Order does not constitute any opinion as to the effect that
the use of this device may have on any warranty either expressed or implied
by the vehicle manufacturer.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF ANY
CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED
BENEFITS OF THE "CAGLE MARK II AUTOMATIC FUEL CONTROL® DEVICE.

                                    SUMMARY



      Cagle Corporation requested an update of their existing exemption,
Executive Order No. D—75—5, from the prohibition in Vehicle Code Section 27156

for their "Cagle Mark II Automatic Fuel Control" fuel pressure regulator for

automobiles.   In particular, Cagle requested that the exemption be updated to

include all 1983 model—year gasoline—powered vehicles with conventional

carburetors.

      Based on previous emissions tests performed on 1979 model—year vehicles,

and an engineering evaluation of 1979 through 1983 model—year vehicle‘s fuel

systems, the staff has concluded that the Cagle fuel pressure regulator will

have no adverse effect on emissions from 1983 model year automobile.

      The staff recommends granting Cagle‘s request to update the exemption.

Evaluation of "Cagle Corporation Mark II Automatic Fuel Control" Device
for Exemption from the Prohibitions in Vehicle Code Section 27156 in
égggrdance with Section 2222, Title 13 of the California Administrative

I.    INTRODUCTION

      Cagle Corporation of 2667 East 28th Street, Suite 517, Long Beach

California 90806 requested by letter dated August 9, 1983, an update of

the existing Air Resources Board‘s Executive Order No. D—75—5.    The

applicant requested that the exemption from the prohibitions in Vehicle

Code Section 27156 for their "Cagle Mark II Automatic Fuel Control"

device be updated to include all 1983 and older model—year motor vehicles

thaf are powered by gasoline engines with conventional carburetors and

mechanical or electrical fue] pumps with and without fuel recirculation
systems.

II.   CONCLUSION
      Previous Air Resources Board (ARB) confirmatory emissions tests

showed that the use of the "Cagle Mark II Automatic Fuel Control" device
did not have an adverse effect on the exhaust emission control system of

1979 modelT—year vehicles.   The staff then granted an exemption from the

Vehicie Code for 1979 and older model—year vehicles.

      Updates to include 1980, 1981, and 1982 model—year vehicles were

granted on the basis that the vehicles fuel system on 1979, 1980, 1981

and 1982 were similar in design.
      An engineering evaluation of the vehicle‘s fuel system design on

1983, 1982, 1981, 1980, and 1979 modeT—year vehicles indicate that the

use of the Cagle device should not have an adverse effect on 1983

model—year vehicles.


III.    RECOMMENDATIONS

       Based on the above, the staff concluded that granting the Cagle
Corporation an exemption from the prohibitions in Vehicle Code Section

27156 for its "Cagle Mark II Automatic Fuel Control" device for 1983 and

older model vehicles that are powered by gasoline engines with

conventional carburetors and mechanical or electrical fuel pumps with or

without fuel recirculation system is justified.     The staff, therefore,

recommends that Executive Order No. D—75—6 be adopted.

IV.    DEVICE DESCRIPTION AND OPERATION

       The "Cagle Mark II Automatic Fuel Control" is a fuel pressure

regulator installed between the fuel pump and the carburetor.     It has

three external fittings: (1) a fitting at the top for measuring intake

manifold vacuum; (2) an inlet fitting marked "PUMP" for connection to the
fuel pump; and (3) an outlet fitting market "CARB" for connection to the

carburetor.   It is designed to reduce the fuel supply pressure under low

fuel demand conditions but still maintain the required fuel flow to the

carburetor under all operating modes.     The device is controlled by intake
manifold vacuum operating on a spring balanced Buna—N diaphragm.

       A cross sectional view of the device is shown in the Appendix.

       For a more detailed description of the device and its operation,

the reader is referred to ARB Staff Report dated December 17, 1980,

entitled "Cagle Corporation Mark II Automatic Fuel Control Device for

Compliance with the Requirements of Section 27156 of the Vehicle Code".
V.     DISCUSSION

       Prior to issuing Executive Order No. D—75—2 (which exempted 1979

and older model—year vehicles) the staff performed comparative exhaust

                                          2.


emissions tests on a 1979 Ford Fairmont with a 302 CID engine and on a
1979 Chevrolet with a 231 CID engine.          The results of these tests were as

follows:

      In addition, fuel pressure measurements were taken before and after

the regulator for various manifold vacuums.                 The results were as follows:

       9                      4.2                           3.05                 1. 15

       7                      4.2                           3.70                0. 50

       5                      4.2                           3.88                0. 32

      Then on September 9, 1980, June 15, 1981, and on August 20, 1982,

the applicant requested, via letters, that the exemption be updated to

include 1980, 1981 and 1982 model—year vehicles, respectively.     In

response to those requests, the staff compared the vehicle‘s fuel system

design on some 1979, 1980, 1981 and 1982 model—year vehicles.     Since no

significant differences, that could adversely affect exhaust emissions,

were noted, no additional tests were requested for the updates.

      In response to this request, the staff compared the vehicle‘s fuel

system on some 1983, 1982, 1981, 1980 and 1979 model—year vehicles.      No

significant differences were noted between the vehicle‘s fuel system

design even though newer cars tend to operate more fuel efficient.      The
staff, therefore again, did not recommend or perform any additional tests.
