Today's fuel injected engine requires an electrical fuel pump to deliver fuel from the gas tank to the
engine, when the pump drive gears wear out, it will make a 'Buzzing' sound, it a sign of a fuel pump
failure, get the fuel pump replaced before your car breaks down. Fill your gas tank every 1/4~1/2
tank will help to prolong the life of the fuel pump. When the fuel level is down to the bottom, the
fuel pump will pick up all the contaminants from the bottom of the gas tank and plug the fuel pump.
Gasoline also helps to prevent the fuel pump from overheating.
