On newer cars, electric fuel pumps are typically installed inside the gas tank. These pumps are prevented from overheating by immersing them in fuel. Running the vehicle on an almost empty tank may cause the pump to sustain some damage.
Fuel pumps siphon and transport fuel from the gas tank to the combustion chambers of a vehicle's engine. These pumps are categorized into two types: electric and mechanical. Non-electric fuel pumps, which provide additional pumping action in carbureted engines, are connected directly to the engine. Electric pumps, which are powered by the car's battery, can also be mounted beside the fuel tank. When using electric pumps, the amount of fuel carried from the tank to the engine is automatically regulated by the engine's computer.
