Fuel Gauge: Description and Operation
Fuel Usage
DESCRIPTION
This system consists of green and amber indicator lights located on the fuel gauge or telltale lamp cluster, a switch mounted on the instrument panel
behind the gauges and an interconnecting vacuum hose and tee.
OPERATION
The system operates on engine vacuum through a dual contact vacuum sensing switch. When the accelerator is operated slowly and smoothly, engine
vacuum remains high and the switch passes current to the green indicator light which indicates economical fuel consumption. When the accelerator
pedal is depressed rapidly, vacuum decreases and the switch passes current to the amber indicator light, which indicates high fuel consumption. The
amber indicator light will glow when the ignition switch is in the On position with the engine stopped.
