The fuel pump is located at the fuel tank and is designed to convey the required amount of fuel from the tank to the engine at the necessary pressure. There are different types of fuel pump designed according to their demand in the USA. In older cars with a carburettor, mechanical fuel pump is used. A camshaft is required to drive the mechanical fuel pump. The main problem with these types of fuel pump is that the supply pressure is very low, i.e. 0.2 to 0.3 bar. So the demand of these types of fuel pump is limited now. On the other side, electric fuel pump has a supply pressure of 2 to 2.5 bar or 30 to 40 pounds per square inch. They utilize fuel injection systems to spray the fuel directly into the engine. This is a fuel efficient method because the injection system can control the flow of fuel that goes into the engine. Fuel pressure needs to be within certain specifications for the engine to run efficiently. If the fuel pressure is too high then the proper combustion of fuel does not take place making the engine inefficient and a pollutant.
