Vehicles need fuel pumps to pump the fuel to the engine.  This is necessary because the gas tank isn’t on the same side of the vehicle as the engine.

There are two different varieties of fuel pumps.  Electrical fuel pumps are used in cars that are equipped with electronic fuel injection systems.  Mechanical fuel pumps are used in carbureted cars.

The carburetor transports gas through a vacuum.  Then, the mixture of gas and air brought by the vacuum to the engine also moves the fuel along lines to get to the engine.  However, more help is needed, so carbureted engines have a mechanical fuel pump.  The pump is positioned next to the car engine.

Electronic fuel injection is a delivery system where fuel is squirted into the engine chambers.  The fuel pump is either inside or next to the fuel tank.

Vehicles that have electronic fuel injection usually don’t experience a fuel pump failure.  However, when a failure does occur, the vehicle will begin to sputter and then die.  Also, you won’t be able to start the car back up.  It is always a good idea to purchase an auto warranty in case of a situation such as this.  You don’t want to end up paying costly repairs that are unnecessary.
