Fuel Pump

The fuel pump transfers fuel from the gas tank of your car to the engine. Typically, electrically powered fuel transfer pumps are situated either inside or on top of the fuel tank. A fuel pump assembly may be made of steel and plastic. When removing the fuel pump, verify that the gasoline line doesn't have any pressure. Ensure there are no electrical outlets that are active close to the gas tank.

A gas pump at a filling station used to inject gasoline (petrol), diesel, or other types of liquid fuel into moving vehicles is also a kind of fuel pump.

How Many Types of Fuel Pumps are There?

Lower-pressure manifold injection systems use electric fuel pumps mounted inside the fuel tank. The high-pressure direct injection system uses mechanical fuel pumps that are mounted on the engine. Diesel marine engines use high-pressure fuel pumps, Ports, and Helix. The positive displacement fuel pump with a diaphragm works by the diaphragm expanding and contracting to suction fuel. Similar to a positive displacement pump, a plunger-type fuel pump draws and distributes fuel through the reciprocating action of the plunger.

When Should You Replace Your Fuel Pump?

You will know that you need a fuel pump replacement when your fuel pump or injection pump is making a loud noise. You may also face difficulty starting your vehicle. Your car's engine will sputter and potentially stall if the fuel pump, which can be a petrol or diesel pump, is unable to pump out a steady stream of fuel at higher speeds. If your vehicle needs more fuel than normal, that also means that you require a fuel pump replacement. Besides, when determining the cause of problems with a fuel transfer pump, the fuel filter should be checked and replaced if necessary.

The fuel pump replacement cost depends on the type of vehicle and the age of your vehicle. You can expect a reasonable fuel pump cost with different global suppliers on Alibaba.com.
