Purpose and compatibility

The presented pump belongs to the Fuel pumps and level sensors group and is used in Mercedes G-Class and S-Class models from the W463 and W220 series, in G320 and S320 CDI diesel versions. The component's design is adapted to the parameters of diesel fuel supply systems, which allows for maintaining appropriate pressure and fuel flow efficiency under typical operating conditions.

By using an original manufacturer solution, the correct connection geometry and electrical configuration are maintained, which facilitates installation in the factory-intended location in the vehicle. The pump works with the factory fuel system and electronic engine control systems, minimizing the risk of starting problems or uneven engine operation.

Technical characteristics of the Diesel system

The fuel pump for the Diesel engine in Mercedes G320 and S320 CDI models is responsible for supplying the injection system with diesel fuel at the appropriate pressure and stable flow rate. In diesel systems, it is crucial to maintain a constant fuel supply to the high-pressure pump, which is why a functional component of this type contributes to:

• easier cold and warm engine starts,
• stable idle speed,
• proper dynamics during acceleration,
• reducing the risk of air entering the fuel system.

A properly selected fuel pump also supports maintaining the correct mixture composition and the proper operation of exhaust emission control systems, which is important during technical inspections and computer diagnostics.

Condition, origin, and benefits of choosing a used part

The offered item is a used fuel pump sourced from a dismantled Mercedes vehicle. Choosing an original second-hand part allows you to maintain the factory operating parameters of the fuel system while reducing costs compared to purchasing a new component. This solution is particularly beneficial for repairs of older G-Class and S-Class generations, where both technical compliance and service economy are important.

The pump from this offer is intended for users and workshops that prefer installing OEM components instead of replacements with uncertain parameters. Thanks to the preservation of the original design and manufacturer specifications, you can reduce the time required for fitting and avoid modifications to the fuel system.

Professional selection by numbers and integration with electronics

Selecting a fuel pump in modern Mercedes vehicles requires taking into account OEM markings and interchangeable numbers to ensure full compatibility with a specific engine version and vehicle year. In this case, all key identifiers are available in the technical specifications section, which facilitates verification of compatibility with a given car, including selection by VIN number.
