Purpose and Function in the Injection System

The presented fuel injector lines set is dedicated to the OM651 Diesel engine used in the Mercedes C-Class W205 generation. It is responsible for precisely delivering high-pressure fuel from the common rail to individual injectors, which directly impacts engine smoothness, performance, and cold start stability.

Replacing the set of lines is particularly recommended when:

• modernizing or repairing the injection system in a diesel engine,
• detecting leaks or micro-cracks in the lines,
• performing service work after an injector or common rail failure.

Technical Characteristics and Compatibility

The set of lines has been developed in accordance with the vehicle manufacturer's requirements for engines powered by Diesel fuel. The design of the lines is adapted to the high operating pressures typical of modern common rail systems, and their appropriate shapes and ends allow for correct routing within the engine bay and a leak-free connection to the rail and injectors.

To ensure correct selection for a specific engine version and model year, it is advisable to verify compatibility using the OEM part number and interchangeable numbers visible in the technical specifications section. This minimizes the risk of purchasing a part with a different shape or connection layout.

Benefits of Using an Original Set of Lines

Using a dedicated set of injector lines in a Mercedes W205 with an OM651 engine offers a range of practical service and operational benefits:

• Correct Geometric Fit – the lines are routed according to the factory path, which reduces stress and the risk of abrasion.
• Stable Injection System Operation – connections remain sealed, promoting even fuel delivery.
• Hassle-Free Installation – the design of the lines is prepared for installation in the original mounting points in the engine bay.

The product comes from the Mercedes brand, which means it adheres to the quality standards appropriate for parts factory-fitted in vehicles of this make.

Condition, Service Application, and Selection by Numbers

The fuel injector lines set is offered as a used part, making it an attractive solution for cost-effective fuel system repairs in a diesel engine. Such components are often chosen for comprehensive repairs of OM651 units when multiple parts need replacement simultaneously, and cost optimization while maintaining adequate quality is a priority.

To further safeguard against selection errors, it is worth using the practical tips described in the blog article on verifying parts by numbers.
