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, CR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF ANY

                                    SUMMARY



      Cagle Corporation requested an update of their existing exemption,

Executive Order (E.0.) No. D—75—7, 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 1984 and

older modei-year carbureted vehicle exemptions be updated to include all 1985

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 1985 model—year vehicle‘s fuel

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

have no adverse effect on emissions from 1985 model year automobile.

      The staff recommends granting Cagle‘s request to update the Section

27156 exemption to include 1985 model—year vehicles equipped with conventional

carburetors.

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



I.    INTRODUCTION

      Cagle Corporation of 2667 East 28th Street, Suite §17, Long Beach

California 90806 requested by letter dated May 1, 1985, an update of the

existing Air Resources Board‘s Executive Order No. D—75—7.    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 1985 and older model—year motor vehicles that are powered by

gasoline engines with conventional carburetors and mechanical or electrical

fuel pumps with and without fuel recirculation systems.    E.0. No. D—75—7

exempts 1984 and older model—year vehicles of this type.

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 model—year

vehicles.   An exemption from the Vehicle Code for 1979 and older model—year

vehicles was granted.

      The manufacturer was granted updates of the E.0. to include 1980 through

1984 model—year vehicles on the basis that the vehicles‘ fuel systems on 1979

through 1984 were similar in design.

      An engineering evaluation of the vehicles‘ fuel system designs on 1985

model—year vehicles indicates that the use of the Cagle device should not have

an adverse effect on 1985 model—year vehicles.


III.   RECOMMENDATIONS

       Based on the above, the staff concludes that the "Cagle Mark II

Automatic Fuel Control" device meets the criteria for an exemption from the

prohibitions in Vehicle Code Section 27156 for 1985 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.   The staff, therefore, recommends that Executive Order No. D—75—8 be

issued to Cagle Corporation.

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.    The device 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".

Y.     DISCUSSION

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

older model—year vehicles) the staff performed comparative exhaust


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:

      Through a series of letters covering several years, the applicant

requested that the exemption be updated to include 1980 through 1984

model—year vehicles, respectively.     In response to those requests, the staff

compared the vehicle‘s fuel system design on 1979 through 1984 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 1979 through 1985 model—year vehicles.    No significant differences

were noted between the vehicles‘ 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.
