What are the components of the fuel system?

1 Fuel Tank The fuel tank is the main storage for the fuel that runs the vehicle. 2 Fuel Injectors: Sprays a fine mist of fuel into the combustion chamber of each cylinder or throttle body, depending on design. 3 Fuel Fill Hose The Fuel Fill Hose is the main connector from the gas cap to the fuel tank.

How are fuel lines connected to the engine?

The Fuel Lines connect all of the various Fuel System components. Steel lines and flexible hoses carry the fuel from the tank to the engine. When servicing or replacing the steel lines, copper or aluminum must never be used. Steel lines must be replaced with steel. When replacing flexible rubber hoses, the proper hose must be used.

When do you use a fuel return line?

These are often used in combination with fuel return lines. The goal of this section of the overall system is to ensure that gasoline vapors are not released into the ambient air.

Where does the fuel go in a fuel tank?

The fuel, which can be either gasoline or diesel is stored in a fuel tank. A fuel pump draws the fuel from the tank through fuel lines and delivers it through a fuel filter to either a carburetor or fuel injector, then delivered to the cylinder chamber for combustion. 1. Fuel Tank

Think of it as your vascular system, with a heart (fuel pump), veins (fuel lines) and kidneys (filter). A failure in any of these fuel system components has the same devastating effects as in your body. Let’s get a little more in-depth with each part… Basically a holding tank for your fuel.

How does a computer control the fuel system?

Instead of a carburetor to mix the fuel and air, a computer controls when the fuel injectors open to let fuel into the engine. This has resulted in lower emissions and better fuel economy. The fuel injector is basically a tiny electric valve which opens and closes with an electric signal.

Is there a fuel filter before or after the fuel pump?

Fuel injectors and carburetors have tiny openings which clog easily so filtering the fuel is a necessity. Filters can be before or after the fuel pump, sometimes both. They are most often made from a paper element, but can be stainless steel or synthetic material and are designed to be disposible in most cases.

Why is fuel used in a fuel pump?

Fuel is used to lubricate the fuel pump. Water in the fuel can reduce the lubrication of the pump causing wear, and can cause the highly machined surfaces of the pump to rust or corrode. Water is also a catalyst for acid formation and acts as a host for organic growth, which can damage the fuel system.

Who is the manufacturer of electronic fuel injection?

The electronic fuel injection system was designed and built by Bosch and has been used successfully on several VW models and other cars. Complete service information for the fuel injected engine is beyond the scope of this manual.

Is the fuel pump part of the body?

There is a fuel pump, fuel tank, fuel lines, fuel filter, fuel injectors, and carburetor. It is really no different than the heart, veins, and kidneys of your body working together to keep you moving. If just one of these components were to malfunction, it could interfere with the entire fuel transferring process.

Where is the fuel filter located in a car?

The fuel filter is usually positioned around the fuel pump, either before or after it. When the fuel gets pumped from the fuel tank, any tiny particles and contaminants in it are blocked by the filter before the fuel enters the engine. 4) Fuel Injectors – The fuel injectors of modern vehicles are controlled by electric sensors and computers.
