In most of the modern cars, the fuel pump uses the electricity and it is positioned inside the fuel tank. The pump generates positive pressure inside the fuel lines, by pushing the fuel to the car engine. The high pressured gasoline increases the boiling point. By placing the electrical pump inside the fuel tank puts the elements less possibly to control or pump the gasoline vapor well from the engine, submerged in the cool liquid. Another advantage of placing the electrical pump inside the fuel tank it allows to burn the fuel quickly and to start the engine fast. Although the electrical components could spark and burn the fuel vapors, the gasoline will not blow up.
Thus submersing the electrical pump inside the tank is one of the safest and best places to install it. In many of the vehicles, the fuel pump provides a steady flow of fuel to the car engine and the fuel which is not used is pushed back to the tank. This in addition lessens the chance of gas boiling because it is not kept near to the hot engine for very long time. The fact is that the ignition switch doesn’t carry the current to the gasoline tank but it triggers a relay that would control the high power load.
Apart from vehicle, the electrical pump is also used in several other places such as for pumping water from the ground to the water tank. Today in almost all the advanced machines and devices uses the electrical pumps such as washing machines, dishwashers and many more. Apart from using fuel, today most of the vehicles use the electrical motor or pump.
