Purpose and role in the fuel system

The presented tank belongs to the Fuel tanks and filler pipes category and is a key component of the petrol engine supply system. It is responsible for the safe storage of fuel, stable power supply to the pump, and proper routing of lines and mounts, in accordance with the factory chassis geometry of the W177 and W247 models.

The bare version of the tank is prepared for the transfer of factory equipment (pump, sensors, lines), which allows for maintaining the vehicle's original configuration and reducing service costs while ensuring high-quality repairs.

Construction, installation, and compatibility

The tank has been designed to work with the M260 engine and 4MATIC drive, ensuring that its shape, mounting points, and line routing are matched to the chassis architecture of these versions. The appropriately selected 51-liter working capacity provides a favorable compromise between range per tank and vehicle weight.

In assembly practice, this means:

• factory placement of brackets and mounts to the body,
• adaptation to the drivetrain with the driveshaft and 4MATIC components,
• geometry of chambers and fuel channels designed for a petrol engine.

As a result, the tank allows for the restoration of the original fuel system configuration without the need for structural modifications.

Operational characteristics and application benefits

As a component dedicated to petrol, the tank supports stable operation of the supply system, reducing the risk of airlocks and ensuring proper conditions for the pump and equipment. The design intended for modern M260 units promotes even fuel consumption under various driving conditions, which translates into predictable vehicle behavior.

Key benefits of using this component include:

• maintaining the factory geometry of the fuel system in W177 and W247 models,
• the ability to use existing equipment, which facilitates service and reduces costs,
• compatibility with 4MATIC drive, essential for chassis and fuel system repairs.

Condition, origin, and service application

The item comes from the segment of used original parts, which in workshop practice often means a favorable price-to-quality ratio while maintaining factory fitment. This type of tank is particularly useful for accident repairs, mechanical chassis damage, or the need to replace the component due to corrosion or leaks.

In service applications, it will prove useful both in professional workshops specializing in the Mercedes brand and for informed users looking for a technically matched solution for their vehicle.

Selection, diagnostics, and technical knowledge

When selecting a fuel tank for a specific body and engine version, it is worth paying attention to compatibility with the drivetrain and fuel type. Proper matching translates into operational safety, correct operation of the supply system, and the absence of assembly problems.

To better understand the relationships between the tank, pump, and injectors, and to learn practical tips on diagnostics and operation, it is worth referring to the guide Fuel system – injectors, pumps, and fuel tank: maintenance and regeneration, which discusses, among other things, selecting parts by catalog numbers and typical symptoms of failures.
