Used Mercedes-Benz GLB Fuel Tank

The Mercedes-Benz GLB (X247) is a single generation launched in 2019 and remains in production, with a facelift introduced for the 2024 model year. For fuel tank fitment, the engine code is the most important detail — two GLBs from different years can share a tank if they share the same engine code, while two from the same year can differ if the engines differ. Confirm with the breaker whether any mounting or ancillary bracket changes were made around the 2024 facelift point, as these can affect a direct swap even when the core tank dimensions match.

The 2024 model year marks the GLB facelift, so a pre-facelift tank (2019–2023) crossing into a 2024 or later car sits right on a known production boundary. The engine code on your V5 or a VIN check is the single most useful detail here — if both vehicles share the same engine code and fuel type, the core tank is likely compatible, but mounting points or sender-unit connections can change around a facelift. Route the specific part number cross-check to the breaker against your registration to be sure.

Yes — petrol and diesel fuel systems are fundamentally different, so a petrol GLB tank will not be a straight swap for a diesel GLB and vice versa. Always confirm the fuel type matches before purchasing, and give the breaker your engine code (found on the V5 or via a VIN check) to make certain the donor vehicle's tank was built for the same fuel type as yours.

Trim level does not affect fuel tank fitment on the GLB — SE, Sport, and AMG Line are cosmetic and equipment packages, not mechanical variants. The fuel tank follows the engine code, fuel type, and gearbox type, so a tank from any trim can fit another provided those mechanical details match. You may find that minor bracket or strap configurations differ depending on the exact build, so confirm the specific part against your registration with the breaker before buying.

The GLB 220d typically uses the OM654 diesel engine family, but the precise engine code suffix matters because Mercedes-Benz uses several OM654 variants across different outputs and model years. Check your V5 logbook or run a VIN check to get the exact code, then supply that directly to the breaker — this is the single most reliable way to ensure the donor tank came from a mechanically identical vehicle.

For the fuel tank itself, the drivetrain (4MATIC vs front-wheel drive) is generally less critical than the engine code and fuel type, but the tank's mounting arrangement or shape can occasionally differ to accommodate 4MATIC driveline components underneath the vehicle. Provide your full engine code, fuel type, and drivetrain to the breaker and ask them to verify the part number matches your registration — this takes the uncertainty out of the swap.
