Get to the fuel pump
The fuel pump is a essential component of an internal combustion engine system. The fuel pump pumps the fuel from the tank to the injection system. The pump is designed to pump fuel from the fuel tank to the engine and delivered at low pressure to the carburetor or at high pressure to the fuel ignition system.
There are two types of fuel pumps: mechanical and electric. In most cars, we find the electrical fuel pump.
You will find mechanical fuel pump mostly in old/carburetor vehicles. Mechanical fuel pumps rely on movement of the piston to draw fuel.
Fuel pumps can be located inside or outside of fuel tanks depends up on the vehicle. On most of the vehicles you’ll find the fuel pump inside the tank.
