Fuel Pump
The fuel pump sends fuel from the gas tank to the engine. In modern cars, fuel pumps are usually electrically powered and located directly in or on the fuel tank. The ease and cost of replacement depend on the car’s design, and it should be undertaken only after determining the problem isn’t electrical or related to the fuel lines.
In the fuel-injection system, used on some engines, the petrol and air are mixed in the inlet manifold.
A fuel pump draws petrol out of the tank through a pipe to the carburetor.
The pump may be mechanically worked by the engine—or it may be electric, in which case it is usually next to or even inside the fuel tank.
Keeping the petrol tank safe. For safety, the petrol tank is placed at the opposite end of the car from the engine.
Inside the tank, a float works an electrical sender unit that transmits current to the fuel gauge, signaling how much petrol is in the tank.
The tank has an air vent—usually a pipe or a small hole in the filler cap—to allow air in as the tank empties. Some of the latest systems have a carbon filter so that fuel fumes do not escape.
