Where is the fuel pump installed?
1 Answers
The fuel pump is installed inside the fuel tank. Its function is to draw gasoline from the fuel tank and deliver it through pipelines and the fuel filter to the float chamber of the carburetor. Thanks to the fuel pump, the fuel tank can be placed at the rear of the vehicle, away from the engine and at a lower position. Fuel pumps can be divided into two types based on their driving methods: mechanically driven diaphragm type and electrically driven type. The diaphragm fuel pump is representative of mechanical fuel pumps, used in carburetor engines and driven by an eccentric wheel on the camshaft. The electric fuel pump, on the other hand, is not driven by the camshaft but relies on electromagnetic force to repeatedly move the pump diaphragm. This type of electric pump allows for flexible installation positions and helps prevent vapor lock.
