Now, it is time to explore all about the functionality of the fuel system in German Car. But first and foremost let’s be familiar with the fuel system:

What Is A Fuel System?

The fuel system is made up of several parts consisting of a fuel tank, filter, pump, and injection nozzles or more commonly known as carburetors. The main purpose of the fuel system is to furnish fuel to the engine as required. However, if any of the aforementioned parts doesn’t operate accurately then the performance of the car is affected immediately. Thus, it is vital to maintain your car and not to miss out on any monthly inspections to avoid the hassle.

Explore all about the Function of the Fuel System:

As we mentioned earlier, the main purpose of a fuel system is to dispense fuel to the engine of the automobile. Read below to know further about it:

The Chamber Section:

Firstly, the fuel directly goes to the cylinder chamber. That’s where it is combined with the air. Once the fuel is mixed with air then it gets evaporated or vaporized. Now, it is ready to manufacture energy. The main fuels used in German automobiles are petrol, diesel, and gasoline. So, the fuel pump pulls out the fuel from the tank via fuel lines and transfers it via a fuel filter to a carburetor or a fuel injector. Afterward, it goes to the cylinder section or chamber for combustion.


The main components of the fuel system are mentioned beneath:

1. Fuel Tank:

The fuel tank is mainly known as the foremost storage for the fuel. The entire automobile is dependent on it as the vehicle can’t even start without it. It is usually located at, or beneath the back of the automobile.

2. Fuel Injectors:

It is linked to the throttle body. Mainly, it works by showering the combination of fuel and air into each combustion section. This part also varies with the aesthetics of every automobile. The fuel injectors control the quantity of fuel that goes directly into the combustion chamber. It also manages the time with the amount of fuel injected into the combustion chamber.

v  The Structure of Fuel Injectors:

It comprises the following parts mentioned below:

  • A nozzle
  • A valve

Here, the valve is anchored within it so the nozzle produces a mixture in the form of a spray. The spray consists of fuel and air droplets (atomization). In simpler words, it’s like perfume or deodorant.

3.      Fuel Fill Hose:

Its main work is to support the gas cap and fuel tank as well. It’s the junction where Gasoline and too many other fuels are deposited in the automobile.

4.      Gas Cap:

Once the fuel is filled then the gas cap operates as a seal for the fill hose. It ensures two main factors which are:

  • Gas doesn’t leak out from the automobile
  • Also, it ensures that the entire fuel system stays pressurized.

5.      Fuel Pump:

The fuel pump function is to generate fuel via a fuel tank. The entire procedure follows through via fuel lines & fuel injectors. Then, the combustion chamber does its job to produce energy.

Types of Fuel Pumps:

There are two types of fuel pumps mentioned below:

Mechanical Fuel Pumps:

The cars are driven via auxiliary belts or chains which are attached to the engine.

Electronic Fuel Pumps:

The electronic fuel pumps are directly associated with the fuel injection system. The electronic fuel pumps are far more durable combatively other fuel pumps.

So, if your car has an electronic fuel pump then it is more likely to have fewer issues than its mechanical counterparts.

1.     Fuel Filter:

The fuel filter is directly related to the fuel delivery system. Overall, if the car has a carbonator then the fuel filter is the key to operating the fuel system. The fuel injectors are more sensitive to damage from dirt particles. That’s where the electric fuel pump works to ensure dust doesn’t remain stuck. So, many automobiles have two car filters. Mostly, the first filter gets damaged in the process. The first filter is located within the gas tank and the other one is aligned with fuel injectors or carburetors. You will replace the filter in line if it’s clogged with a large amount of dirt.

2.     Fuel Lines:

The fuel lines are attached to the different Fuel System components. You should never use copper or aluminum while changing the steel lines. You should always replace the steel lines with the steel material only.

3.     Fuel Gauge:

The fuel gauge functions as a vehicle’s dashboard only. Its main purpose is to let the driver know about the fuel tank. Moreover, the fuel gauge system used to be a bit inexact. So, it is advisable to learn about the fuel gauge before taking your classic car on the drive!

4.     Fuel Return Lines:

The function of fuel return lines is to send back the gas tank for recirculation. It also absorbs gasoline vapors. The vapors are then returned to the gas tank cool. Here, they are converted into liquid form. If the engine is diesel-powered then the water vapors are utilized as a cooling mechanism for the fuel injector. The other parts are emission vapor controls, fuel pressure regulator, and pulsation damper as well. Moreover, if you face any car issues then make sure to get the impeccable services via Kfzteile24.
