In a pressurized pump system, how does fuel move from the tank to the dispenser?

• A. In the tank
• B. The pump pushes the fuel in the line up to the dispenser.
• C. Gravity feeds the fuel to the dispenser
• D. A separate pump pulls the fuel from the dispenser

Answer: (B)

Fuel movement in a pressurized system is driven by a pump that pressurizes the line and pushes fuel from the storage tank toward the dispenser. The tank stores the fuel, but it’s the pump that supplies the force to move it through the delivery line, overcoming any friction and elevation changes, so fuel reaches the dispenser where the nozzle can deliver it to a vehicle. Relying on gravity wouldn’t provide the consistent, regulated flow those systems require, and a pump pulling from the dispenser isn’t how the fuel is moved from the tank to the nozzle. So the fuel is pushed along the line by the pump to the dispenser.
