What is the operational fuel capacity (usable fuel)?

• A. 75 gallons
• B. 100 gallons
• C. 120 gallons
• D. 90 gallons

Answer: (B)

Operational fuel capacity is the amount of fuel you can actually burn in normal use—the usable fuel. It isn’t the total amount the tank can hold if some fuel remains inaccessible due to the tank’s shape or the pump pickup. So, you subtract any unusable fuel from the tank’s total to get what you can rely on during operation. In this scenario, the usable fuel is 100 gallons, which is why that option is the correct choice. The other numbers don’t reflect the fuel you can actually draw from the system.
