An external fuel pump moves gasoline from the tank to the engine, often using an impeller or gear-rotor mechanism to create pressure that propels the fuel through the line.

Gear pumps offer advantages over fluid pumps in terms of high pressure delivery, constant flow under varying loads, and the ability to handle viscous fluids effectively.

To calculate the efficiency of a gear pump, you must measure the input power and the output power, and then divide the output power by the input power. This ratio is then multiplied by 100 to get the efficiency percentage.
