Purpose and compatibility

The presented fuel tank has been designed specifically for BMW 5 Series E60 models in the M5 version with the petrol-powered S85 unit. The design corresponds to factory BMW solutions, which facilitates installation in original mounting points and proper connection of fuel lines and accessories.

The component belongs to the Fuel tanks and filler pipes group, integrating both the fuel storage space and the refueling path via the included filler pipe into one part. This solution reduces the number of connections and potential leak points.

Tank and filler pipe construction

The BMW 5 Series E60 M5 S85 Petrol Complete Plastic Fuel Tank with Filler Pipe is made of material adapted for petrol use, which minimizes the risk of internal and external corrosion. The use of composite material allows for a favorable weight while maintaining adequate rigidity and resistance to operational loads.

The integral fuel filler pipe ensures proper fuel routing from the filler cap to the inside of the tank, while also facilitating installation in the E60 M5 body. The design provides for compatibility with factory body elements and covers, which allows for maintaining the original fuel system geometry and proper tank venting.

Performance parameters and role in the fuel system

The tank is adapted for operation in the petrol supply system typical for the S85 engine. The properly shaped interior of the tank promotes stable fuel pump supply under various driving conditions, which is particularly important in a sports-oriented car like the BMW M5.

The appropriately selected weight of the element supports maintaining the correct load distribution in the rear part of the vehicle, which is important for handling and driving characteristics. Using an original tank from this group allows for maintaining factory fuel system performance parameters and reducing the risk of supply issues during dynamic operation.

Condition, origin, and benefits of using OEM used parts

The offered fuel tank is a used element, originating from original BMW production. Choosing an original part from dismantling allows for maintaining compliance with factory specifications while reducing costs compared to a new component. For M5 S85 models, this is of particular importance, as the fuel system is precisely tuned to the engine's characteristics.

Using original elements from this group promotes maintaining the consistency of the entire fuel system and facilitates future diagnostics and service. The tank is ready for further operation after proper installation and connection to the existing fuel system.

Selection by part numbers and technical support

The element has a dedicated OEM part number and associated interchangeable numbers, which facilitates precise identification and selection for a specific BMW 5 Series E60 M5 S85 configuration. Before purchasing, it is worth comparing the markings with the vehicle documentation or using VIN-based selection to confirm full compatibility.
