Which statement about fuel storage tanks is true?

• A. They are equipped with sump and drains to collect water and sediment
• B. They have no drains
• C. They never require maintenance
• D. They are always integrated into the wing

Answer: (A)

Managing water and sediment in fuel storage is critical. Water in fuel can settle at the bottom of tanks and cause corrosion, fuel quality problems, or engine icing, so tanks are designed to separate and remove it. A sump provides a low point where water and sediment collect, and drains let technicians remove that liquid without disassembling the tank. This design keeps the fuel clean and makes maintenance straightforward. The statement that aligns with this design is that tanks are equipped with sump and drains to collect water and sediment. The other descriptions—having no drains, never needing maintenance, or always being integrated into the wing—do not reflect how fuel systems are built and maintained in practice.
