Remove the fuel pump mounting bolts and fuel pump. Insatll the fuel pump in the reverse order of removal. HIGH ALTITUDE ADJUSTMENT (USA only) FUEL PUMP BOLTS FUEL LINES When the vehicle is to be operated continuously above 2,000 m (6,500 feet) the carburetor must be readjusted as follows to improve driveability and decrease exhaust emissions. Warm up the engine to operating temperature. Stop and go driving for 10 minutes is sufficient. Remove each pilot screw plug (page 4-10). Turn each pilot screw clockwise 1 turn. Adjust the idle speed to 1,000 ± 100 rpm with the throttle stop screw. Drive new pilot screw plugs into the pilot screw bores (page 4-18). NOTE: This adjustment must be made at high altitude to ensure proper high altitude operation. Attach a Vehicle Emission Control Information Update label onto the frame as shown. Refer to Service Bulletin #SL132 for information on obtaining the label. NOTE: 1 [ Do not attach the label to any part that can Ibe easily removed from the vehicle. Operation at an altitude lower than 1,500 in (5,000 feet) with the carburetors adjusted for high altitudes 'nay cause the engine to idle roughly and stall. When the vehicle is to be operated continously below 1,500 m (5,000 feet), turn each pilot screw counterclockwise 1 turn to its original position after removing each pilot screw plug and adjust the idle speed to 1,000 -± 100 rpm. Drive new pilot screw plugs into the pilot screw bores (page 4-18). Be sure to do these adjustments at low altitude.
