Serviceautosrepair.com - The fuel pump is an essential component of any vehicle with an internal combustion engine. The fuel pump is an integral part of any car or truck. Given the responsibility of literally pumping fuel from the tank to the engine, damage to a faulty fuel pump will always lead to total disaster. Therefore, the driver must be aware of the common symptoms of a faulty fuel pump. The fuel pump's sole purpose is to take fuel from the fuel tank and deliver it according to the demand of the engine. When the fuel pump is working effectively, the car runs smoothly. Some smaller, more concisely constructed vehicles, such as certain models of motorcycles,, do not require a fuel pump because gravity takes care of this job.
Mechanical Fuel Pump & Electronic Fuel Pump
The Mechanical Fuel Pump
Traditionally, all fuel pumps were always mechanical. This means that they operate through a system that runs off of the rotation of the engine itself. A mechanical fuel pump resembles a diaphragm. Mechanical fuel pumps are located on a mount outside of the fuel tank itself It uses the pumping action of that diaphragm shape to create low pressure (10 to 15 psi). The most common malfunction of mechanical fuel pumps comes when the diaphragm inside the pump splits, disturbing the pressure balance of the pump.
The Electronic Fuel Pump
The mechanical pump can not generate the level of pressure needed to work with fuel injection engines. Therefore, a new system which delivers fuel under high pressure (40 to 60 psi) was created. This system is what is known as an electronic fuel pump.
What are the symptoms of a bad fuel pump?
Therefore, malfunctions in the fuel pump can result from an issue in either one of these processes. Let’s take a look at the common signs of these problems.
An engine that will not start
An engine that is hard to start
A check engine light, with a lean code
A whine noise from the rear of the vehicle
An engine that dies after driving a while
Surging
Sudden Loss of Power When the Vehicle Is Under Stress
Vehicle Loses Power While Accelerating
The Engine Sputters at High Speed
where is the fuel pump?
Fuel pump for cars with injection system (EFI) are mostly located in the fuel tank. and to that still use carburetors as the fuel atomizer, the fuel pump is usually located outside of the fuel tank and to the mechanical system is integrated in the engine.
How to Replace an In-Tank Electric Fuel Pump
To replace the fuel pump, it is easy to do when the fuel pump is located outside of the fuel tank. but if for the fuel pump on the engine with EFI injection system, as most are in the tank, then you have to open and release the fuel tank to the fuel pump replacement. after the tank is opened then stay open bolt from the fuel pump itself. but remember, it is dangerous when dealing with fuel and electricity. then I recommend to submit it to the mechanical workmanship as an expert.
How much does Fuel Pump Replacement cost?
It depends on the type of car you drive and you go to a repair shop. and of course also depends on the quality of the spare parts used. but if you want to know the price of fuel pump components itself of course you just go to the websites selling online.
