Application in BMW X3 F25 with B47 diesel engine

Injector supply lines in this model are responsible for directly delivering fuel to the injector nozzles at the correct working pressure. A correctly selected component is crucial for:

• stable operation of the diesel engine across the full load range,
• maintaining correct fuel dosage by the injectors,
• limiting pressure drops in the diesel fuel system.

Being dedicated to the specific BMW X3 F25 model with the B47 engine allows for maintaining the factory routing geometry of the lines and the correct connection points to the injector nozzles.

Construction and technical characteristics

The offered component belongs to the category of injector nozzles, but in practice, it is a set of supply lines that work directly with the injectors in the diesel engine. The BMW design solution ensures:

• appropriate stiffness of the lines while damping engine vibrations,
• precise fit to injector seats and the fuel rail/system,
• resistance to working pressures typical for diesel systems.

The system has been developed with Diesel fuel in mind, meaning material compatibility with diesel fuel and additives used in modern diesel engines.

Component condition and benefits of using OEM parts

The product is a genuine BMW component in used condition, allowing for the preservation of factory fuel system operating parameters while optimizing service costs. Compared to aftermarket alternatives, an OEM part ensures:

• certainty of fit for the B47 engine without the need for modifications,
• compatibility with factory mounting points and line routing,
• consistency with other components of the injection system in the BMW X3 F25.

This solution is particularly beneficial for injection system repairs where maintaining the original configuration of the supply lines is required.

Injection system diagnostics and technical support

In case of problems with diesel engine operation – such as uneven running, power loss, or increased fuel consumption – it is advisable to perform comprehensive diagnostics of the injectors and supply lines. A detailed discussion of symptoms and consequences of faults can be found in the article “Diesel injector faults – how to recognize them and what are the consequences of neglecting them”, which helps to better understand the relationships between the condition of injector nozzles and the overall fuel system's health.
