1.What is the material and application of fuel line?

The fuel pipe is made of reinforced rubber to prevent the diesel engine fuel system from tearing and twisting.

The fuel hose is used to transfer fuel from one place of the vehicle to another place, or from the mailbox to another place of the vehicle.

Fuel hoses come in various sizes and can be applied to different vehicles, from lawn mowers to agricultural tractors, cars and trucks.

According to actual needs, fuel pipes will be made into different shapes.

Modern models can be based on nylon fuel lines. Nylon is easy to use because it is efficient, easy to install and cheap. In addition, stainless steel is also a classic choice because it can withstand more wear and tear.



2.How many kinds of fuel line?

There are two levels of fuel lines in diesel vehicles, including heavyweight and medium heavyweight. Heavy-duty fuel hose can withstand the high pressure between the fuel injection pump and the fuel injector. The medium-weight fuel hose can withstand the light and medium fuel pressure existing between the fuel tank and the fuel injection pump.


3. What is the role of fuel line?

All diesel engines require a method of storing and supplying fuel to the engine, so a fuel supply system has been developed. Diesel engines are based on injectors, which have very tight tolerances and very small precision parts, so the fuel supplied to the engine should be very clean and free of contaminants.


Therefore, the fuel system (fuel line or fuel hose) must not only supply fuel, but also ensure cleanliness. Usually, this is done through a series of filters. For example, the fuel is filtered once by a filter outside the engine and then once by one or more other filters inside the engine. Most of these filters are located in the fuel pipe of each injector.


The fuel system of a diesel engine is much more complicated than that of a simple gasoline engine. Because fuel plays two roles. Obviously, one of the goals is to refuel the engine. The other is the coolant that acts as an ejector. To achieve the second goal, the diesel engine must continuously traverse the engine fuel system at a speed that greatly exceeds that of a single engine. Depending on the application, excess fuel is returned to the fuel pump or fuel tank.


4. What fuel lines do we offer?

They are many types of fuel line to choose from and each of them have different features.


Each type should have its unique OEM numbers and be compatible for specific car model.

There are a few different things to consider when selecting fuel hose.

Virtually everything you need to know will be stamped on the hose itself. However, the first thing you should always do before buying parts is look at your vehicle’s model, engine type.


We offer different fuel types for different car markers, such as Renault, Fiat, Peugeot/Citroen, Ford, Mercedes Benz etc.
