The pump location in a suction pump system is in the fuel dispenser. True or False?

• A. True
• B. False
• C. In the underground storage tank
• D. In the building

Answer: (A)

In a suction pump setup, the pumping unit is mounted at the fuel dispenser. Fuel is drawn from the underground storage tank through the suction line up to the dispenser, where the pump creates the flow, the meter records the amount, and the fuel goes to the nozzle. Placing the pump at the dispenser minimizes suction losses and keeps metering and controls conveniently located, which is why this arrangement is correct. This isn’t typically used with a pump located inside the underground storage tank in a suction-pump configuration, though other system designs may use submersible pumps in tanks—those are different arrangements.
