Mercedes-Benz GLB Fuel Pump Replacement Parts

All GLB variants have at least one electric fuel pump — this is an in-tank unit that sends fuel to the engine, so the part does exist on every GLB regardless of engine. Petrol models (such as the GLB 200, GLB 250 and GLB 35 AMG) have a conventional in-tank petrol pump, while diesel models (GLB 200d, GLB 220d) also use an in-tank lift pump alongside the high-pressure diesel pump. Make sure you and the breaker are clear on which pump you need, as the high-pressure diesel injection pump is a separate part entirely.

The GLB (X247) launched in 2020 and received a facelift in 2023, so a 2020 car is pre-facelift and a 2023 car is post-facelift — they sit either side of a production boundary. Engine codes and fuel type are the primary fitment factors, so if both cars share the same engine code (visible on your V5 or via a VIN check), there is a reasonable chance the in-tank pump unit is compatible, but ancillary and mounting changes mid-production mean you should confirm compatibility against your registration with the breaker before buying.

Yes — fuel type and engine code matter far more than the badge number. A GLB 200 petrol and a GLB 220d diesel use completely different pump assemblies, and you must not mix them; a petrol pump fitted in a diesel application (or vice versa) is a serious mechanical error. Even within the same fuel type, the engine code (for example M282 in the GLB 200 or OM608 in the GLB 200d) is the detail the breaker needs to source the correct unit, so always quote your engine code rather than just the badge.

No — AMG Line, Sport, and SE trim levels are cosmetic and equipment packages that have no effect on the fuel pump. The pump is determined entirely by your engine code and fuel type, so an AMG Line GLB 220d and a standard GLB 220d with the same engine code use the same pump. Tell the breaker your engine code and registration rather than your trim level, and the trim name can be ignored for this part.

The in-tank lift pump itself is generally not coded to the vehicle, unlike some other fuel system components. However, whether any ancillary control module associated with the fuel delivery system requires coding on your specific build is something you should confirm with the breaker against your registration, as Mercedes-Benz can integrate fuel system functions into broader ECU architecture that varies by build date. A good breaker will be able to advise based on their experience with the X247 platform.

The drivetrain layout — 4MATIC four-wheel drive versus front-wheel drive — does not affect the in-tank fuel pump, which is determined by the engine and fuel type as usual. Both 4MATIC and non-4MATIC GLBs with the same engine code share the same pump specification. Quote your engine code to the breaker and the drivetrain variant can be disregarded for this part.
