'Automobile Fuel Pumps'

• A fuel pump is an essential component on a car or other internal combustion engined device
• Mechanical pump: In many earlier cars, the pump is mechanically driven by a lobe on the engine's camshaft
• Decline of mechanical pumps: As engines moved away from carburetors and towards fuel injection, mechanical fuel pumps were replaced with electric fuel pumps, because fuel injection systems operate more efficiently at higher fuel pressures than mechanical pumps can generate
• Electric fuel pumps will also run whenever they are switched on, which can lead to extremely dangerous situations if there is a leak due to mechanical fault or an accident
• Mechanical fuel pumps are much safer, due to their lower operating pressures and because they turn off when the engine stops running
• Electric pump: Now, the fuel pump is located inside of the fuel tank and is usually electric. The pump creates positive pressure in the fuel lines, pushing the gasoline to the engine
