SUMMARY SageBrush Industries, Inc. has requested an exemption from the prohibitions of Vehicle Code Section 27156 for their DualFill device. The DualFill device is used to connect the two fuel tanks on 1973—1986 General Motors 1/2 to 1 ton trucks so that both tanks may be filled from one side of the truck. The DualFill device is available for use on all engines and fuels in the following model year categories of GM 1/2 to 1 ton trucks: (1) model #DF2002 for 1973—1978, (2) model #DF4002 for 1979—1982, and (3) model #DF6002 for 1982—1986. Based on the fact that (1) there are no modifications to the fuel tank vent lines, to the fuel supply lines and to the fuel return lines, (2) the materials used for the DualFill device are compatible with commonly used fuels and (3) there is no significant evaporative loss from the connection points of the DualFill device, the staff believes that the DualFil]l device will have no adverse emissions effect on the vehicles for which the exemption is requested. The staff recommends that SageBrush Industries, Inc. be granted an exemption from Vehicle Code Section 27156 as requested and that Executive Order D—191 be issued.

EVALUATION OF SAGEBRUSH INDUSTRIES, INC. DUALFILL DEVICE MODEL NOS. DF2002, DF4002, AND DF6002 FOR EXEMPTION FROM THE PROHIBITIONS OF VEKICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE I. TRODUCTIO! SageBrush Industries, Inc. of P.0. Box 1944, 4116 Praireview, Colstrip, MT 59323, has requested an exemption from the prohibitions of Vehicle Code Section 27156 for their DualFill device. The DualFill device is used to connect the two fuel tanks on 1973—1986 General Motors 1/2 to 1 ton tricks so that both tanks may be filled from one side of the truck. The DualFill device is available for use on all engines and fuels in the following model year categories of GM 1/2 to 1 ton trucks: (1) model #DF2002 for 1973—1978, (2) model! #DF4002 for 1979—1982, and (3) model #DF6002 for 1982—1986. II. CONC S Based on the fact that (1) there are no modifications to the fuel tank vent lines, to the fuel supply lines and to the fuel return lTines, (2) the materials used for the DualFill device are compatible with commonly used fuels and {3) there is no significant evaporative loss from the connection points of the DuaiFill device, the staff believes that the DualFill device will have no adverse emissions effect on the vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that SageBrush Industries, Inc. be granted an exemption from Vehicle Code Section 27156 as requested and that Executive Order D—191 be issued.

IV. DESCRIPT AND_OPERATION The DualFill device consists of a cross tube and a vent tube made of 16 gauge steel and 18 gauge steel respectively. The exterior of the tubing is plated with .002" of pure zinc with a clear chromate coating. The cross tube is used to connect the two fuel tanks at the fill neck so that both tanks may be filled from one side (refer to Appendix C, page 7). The cross tube has a 2" outer diameter (O.D.) and is 58" in length. At 5" from both ends there is a 1 1/2" vertical tube of 1 1/2" 0.D. Each of these tubes is connected to a fuel tank. In order to maintain proper venting, the vent lines from the fill necks to the tanks are connected by a 56" in length vent tube of 5/8" O.D. At either end of the vent tube there is a vertical tube of 1 1/2" which clamps to the vent line from each tank. V. BISCUSSTON The DualFill device is designed to connect the two independent fue! tanks on GM 1/2 to 1 ton trucks so that both tanks may be filled from one side of the truck. Basically, two modifications are made: (1) the filler hoses which connect the filler necks to the gas tanks are removed from both tanks and replaced with steel tubing thus connecting both fuel tanks and (2) the vent lTines are similarly connected through a vent tube. No emissions—related concerns were raised regarding the fuel system since there were no modifications to the fuel tank vent lines, to the fue!l supply lines or the fuel return lines. The DualFill device is designed for all commonly used fuels. A statement has been provided by the vendor indicating that the DualFill device

is made of 16 and 18 gauge steel with .002" of pure zinc on the exterior of the tubing with a clear chromate coating. This material is acceptable for all commonly used fuels. According to the vendor, no fill problems have been encountered. The existing filler necks and gas caps are used with the device. Appropriate warnings have been placed in the installation instructions for replacement of a malfunctioning gas cap. Hose clamps are used to secure the device to the fill neck, gas tank and vent lines. There are no significant evaporative losses from the connections if the clamps are properly used as described in the installation instructions. Based on these facts, staff believes that no testing is needed for granting the exemption.

APPENDIX A E—Z INSTALLATION INSTRUCTIONS FOR DF2004 Dualfill solves the frustration of two fuel tanks on General Motors Trucks, DUALFILL allows both tanks to fill simultaneously from either side of the vehicle. Tools Required: Screwdriver, or 5/16 nut driver 10mm socket and ratchet Enife {1) Remove existing vent and filler hoses from both fuel tanks. (2) Remove right filler neck from truck box. (3) Insert vent tube under truck box through filler door, install with red end toward left side (drivers side). Tube should lay between frame and truck box. (4) Slide 5/8" hose onto the vertical vent stubs with a #10 clamp on top and bottom of each short hose. (5) Slide the short pieces of 2" tubing over both ends of the cross— tube, insert the crosstube into the truck body through the filler hole. The crosspipe should"fit between the frame and the bottom of the truck box to the rear of the vent tube. (6) —~Slide the 14$" x .3" hoses onto the vertical stubs on the crosstube. Slip two #24 clamps over the hose on each side, insert the short hose onto the tank neck. (7) Install two #36 clamps on each end of the crosstube, slide the 2" hose outward onto the right filler neck. Reinstall the left filler neck and slide the 2" hose over it. (8) Install the 5/8" X 8" hose with two clamps on the left side, make sure you run the vent hose over the crosstube. (9) Connect 5/8" X 6" hose to the right filler neck with two #10 clamps to the vent tube. (10) Tighten all clamps carefully, do not over tighten, fill with fuel, check for leaks, if you find leaks tighten clamps. Check gas cap on the opposite side of the truck for leaks, if so replace the cap with the non vented type. Remember that DualFill works on the gravity flow principle so always fill the tank that is on the high side if parked on unlevel ground. NOTE: On 1979—1982 GM Trucks to increase fill rate try drilling two new holes in the filler neck mounting plate in the truck box and raise the filler neck 4".
