Purpose and function in the fuel system

Thanks to its integrated filtration function, it helps prevent contaminants from entering further system components, which promotes stable engine operation and reduces the risk of premature component wear.

The element has been designed specifically for the BMW E65/E66 architecture, which translates into a proper fit for the factory fuel system, correct hose routing, and maintenance of the required flow parameters.

Original origin and replacement numbers

The tank comes from the BMW OE line, which means compliance with the manufacturer's factory standards regarding materials, geometry, and installation method. The part has a dedicated OEM number and assigned interchangeable numbers, which facilitates precise identification and selection of the correct component for a specific engine version and vehicle year.

Thanks to the presence of reference numbers, it is possible to easily compare it with the currently installed element or verify it by VIN in BMW catalogs, which minimizes the risk of purchasing an incorrect part.

Condition, installation, and service application

The offered expansion tank with filter is a used item, which allows for an economical repair of the fuel system while maintaining the original manufacturer's specifications. This type of part is suitable both for standard replacement of a worn tank and for larger service works related to fuel system regeneration.

The design provided by BMW allows for installation in place of the factory element, while maintaining existing mounting points and hose routing. In practice, this translates into reduced replacement time and no need for fuel system modifications.
