be on the side opposite the fuel dispensing equipment.  For dual fuel servicing vehicles, the outlet, may be on either side.  All portions of the exhaust system which project to the rear of the cab shall be fully shielded from fuel sources.  The shield(s) shall direct fluids spilled from the tank, leaking from the tank, spraying from any leaking seals, or from any other source, away from the exhaust system.  Shields shall be separated from the exhaust system component to be shielded by at least 0.50 inches for the top half of the component and shall extend vertically down from the horizontal center of the component to at least the bottom of the component.  The shielding shall not interfere with the servicing of the pump line strainer or any other component

under the tank body requiring periodic servicing.  A spark arrester conforming to SAE J350 shall be furnished except on turbocharged engines.  The spark arrester shall have an 80 percent efficiency rating when rated in accordance with SAE J350.

3.4.4.1  Exhaust gases in cab.  The exhaust system shall be installed in a manner that will insure that the concentration of oxides of nitrogen (NOx) shall not exceed 5 parts per million (ppm), the concentration of carbon monoxide (CO) shall not exceed 50 ppm and the concentration of sulfur dioxide (SO2) shall not exceed 5 ppm in the driver's compartment after eight hours of operation with all windows and doors closed, with cab air intakes open, with and without all cab heaters operating, and with the chassis engine operating in accordance

with 4.3.11.

3.4.5  Transmission.  Unless otherwise specified (see 3.4.5.3), a manually shifted transmission shall be provided.  The input torque capacity of the transmission shall be at least equal to the maximum torque delivered by the engine.  The vehicle shall be provided with not less than the number of forward speeds specified in table VII.  When more than five forward speeds are required, a multispeed transmission or an auxiliary transmission shall be provided. Gear ratios in the transmission and axle shall be matched to provide a progressive shifting pattern throughout the complete range, and shall provide the vehicle performance required in

3.3.1 through 3.3.1.3.  The transmission shall provide for maximum ease of shifting in all speeds.

SAE J704 power takeoff opening(s) shall be provided.
