STATE OF CALIFORNIA AIR RESOURCES BOARD 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 April, 1987

Issue Date: April, 1987 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 by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue El Monte, California 91731 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.)

summary Cagle Corporation requested an update of their existing exemption, Executive Order (E.0.) No. D—75—9, 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 1986 and older model—year carbureted vehicle exemptions be updated to include all 1987 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 1987 model—year vehicles‘ fuel systems, the staff has concluded that the Cagle fuel pressure regulator will have no adverse effect on emissions from applicable 1987 model—year automobiles. The staff recommends granting Cagle‘s request to update the Vehicle Code Section 27156 exemption to include 1987 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 517, Long Beach, California 90806 requested an update of the existing Air Resources Board‘s Executive Order (E.0.) No. D—75—9. The applicant requested that the exemption from the prohibitions in Vehicle Code Section 27156 for their "Cagle Mark 11 Automatic Fuel Control" device be updated to include all 1987 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—9 exempts 1986 and older model—year vehicles of this type. 1I. 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 specified 1979 model—year vehicles. An exemption from the Vehicle Code Section 27156 for 1979 and older model—year vehicles was granted. The manufacturer was granted updates of the E.0. to include applicable 1980 through 1986 model—year vehicles on the basis that the vehicles‘ fuel systems on 1979 through 1986 were similar in design. An engineering evaluation of the vehicles‘ fuel systems on applicable 1987 model—year vehicles indicates that it is similar in design to that of 1986 vehicles; the use of the Cagle device, therefore, should not have an adverse effect on applicable 1987 model—year vehicles either.

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 1987 and older model vehicles that are powered by gasoline engines with conventional carburetors and mechanical or electrical fuel pumps with or without fuel recirculation systems. The staff, therefore, recommends that E. 0. No. D—75—10 be issued to Cagle Corporation. IV. DEVICE DESCRIPTION AND OPERATION The "Cagle Mark II Automatic Fuel Control" is a fuel pressure reqgulator 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 fue! demand conditions but still maintain the required fue! flow to the carburetor under all operating modes. The device is controlled by intake manifold vacuum operating on a spring balanced Buna—N diaphragm (see the Appendix A for a cross sectional view of the device). 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. BISCUSSION The staff previously 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. Based on the test results, the staff concluded that the Cagle device would not have an adverse effect on 1979 and older model—year vehicles with conventional carburetors and mechanical or electrical fuel pumps with and without fuel recirculation systems. The manufacturer was granted updates of the E.0. to include applicable 1980 through 1986 model—year vehicles on the basis that the vehicles‘ fuel systems on 1979 through 1986 were similar in design. In response to Cagle‘s request that their existing E. 0. D~75—9 be updated to include all 1987 and older model—year vehicles that are powered by gasoline engines with conventional carburetors and mechanical or electrical fuel pumps with and without fuel recirculation systems, the staff compared the vehicles‘ fuel systems on 1986 through 1987 model—year vehicles. No significant differences were noted between the vehicles‘ fuel systems design even though newer cars tend to operate more fuel efficient. The staff concluded that the Cagle device would not have an adverse effect on applicable 1987 model—year vehicles and, therefore, did not recommend or perform any additional tests.

APPENDIX B AUTomatic rust. contror lNSTRUCTlONS FOR |N.S:|'ALLAT|0N Cagle Mark II Automatic Fuel Control System General Motors vehicies, 1976 or newer, may have a roll over or check valve in the center of the filter behind the inlet nut on the carburetor. If this is the case, use the unit in the box labeled: "GM 1976 and newer with check valve in filter." (See iMustration at left.) 1. Locate the metal line that runs between the Fuel Pump and the Carburetor and cut it at the most convenient place but not closer than two inches from the Carburetor so that the connecting hose from the Cagle Unit can be forced at least one inch onto the cut end of the line into the Carburetor. Use a tubing cutter. NOTE: Some vehicles have a length of hose already installed into the Carburetor, In this case, remove the hose connections from the Cagle unit and install it directly in the vehicle hose line by cutting out the proper space to accomodate the unit, This should be done so that the cut ends of the hase can be forced all the way onto each brass fitting with serew clamps securely tightened. 2. Where the line is all metal to the Carburetor, cut out a sufficient gap in the metal line to replace it with the Cagle Unit with its connecting hoses attached and still allow each remaining hose end to be forced onto its respective metal line at least one inch before securely tightening screw clamps. IMPORTANT: Be sure to install the Cagle Unit with the inlet marked "PUMP" connected to the line from the Fuel Pump. Likewise, the outlet marked "CARB" should be connected with the line going to the Carburetor. Make sure there are no sharp edgesor dirt in the fuel line before installing hoses, 3. Connect one end of the Smali Black Hose to the top opening on the Cagle Unit and the other end to a PRIMARY VACUUM SOURCE from the Intake Manifold. {CAUTION: DQ NOT CUT INTO THE SECONDARY SQURCE TO DISTRIBUTOR BY MISTAKE}. Small "tee"is provided for use whereit is necessary to tie into an existing line from the Manifold. Best results will be obtained when the engine is operating as close as possible to factory specifications, i.e., fuel pump pressure, timing, clean filters and good vacuum. CAUTION: MAKE SURE ALL CLAMPS ARE SECURELY TIGHTENED ON EACH CONNECTION. Start engine and run about 30 seconds. Check IMMEDIATELY for any Leaks, (NOT RESPONSIBLE FOR FAULTY INSTALLATION}). DO NOT LUBRICATE OR ATTEMPT TO ADJUST THE } CAGLE UNIT. Mileage may vary due to driving habits or vehicle condition. 148
