TRUE/FALSE: When the LEFT or RIGHT fuel displays drops to zero pounds, the respective feed tank light will illuminate.

• A. True
• B. False
• C. Not Applicable
• D. Unknown

Answer: (B)

Fuel quantity readings and feed-tank warning lights come from different parts of the system. The left and right displays simply show how much fuel is in each tank in pounds. The feed-tank lights, however, indicate a condition in the fuel-feed system—such as a pump fault, a valve position issue, or another transfer-status problem—not just how much fuel happens to be shown on the gauge. Because those lights respond to specific equipment status, not to the raw quantity reading, the display dropping to zero pounds does not automatically cause the respective feed-tank light to illuminate. In short, zero in the quantity display does not directly trigger the feed-tank warning lamp.
