Tachometer (Option) Fuel Gage The tachometer on the optional gage cluster tells you how fast the engine is running. It displays enginespeed in thousands of revolutions per minute (RPM). Your fuel gage shows about how much fuel is in your tank. It works only when the ignition is ON. When the indicator nears E, you still have a little fuel left. You need to get more fuel right away. I NOTICE: Do not operate the engine with the tachometer in the red area,or engine damage may occur. 2-69
