Second Hand Mercedes-Benz X-Class Fuel Tank

The Mercedes-Benz X-Class ran as a single generation from 2017 to 2020 with no significant facelift, so year-to-year differences within that range are generally minor for a mechanical component like the fuel tank. That said, small ancillary or mounting changes can occur mid-production, so always confirm against your registration with the breaker before buying. Supplying your engine code (found on your V5 or via a VIN check) gives the breaker the most reliable basis for matching the part.

The X 220 d and X 250 d both use diesel engines but have different engine codes – the X 220 d runs the 2.3-litre unit (engine code OM 607) and the X 250 d the same basic block tuned differently – and while the tank itself may be shared, pipework, sender units and mounting brackets can vary. Engine code is the single most useful detail here, so quote it to the breaker rather than relying on the badge alone. Never assume a direct swap without the breaker confirming compatibility against your specific registration.

The X 350 d uses a six-cylinder 3.0-litre diesel (engine code OM 642) which is a substantially different drivetrain to the four-cylinder 2.3-litre units in the X 220 d and X 250 d, and the tank configuration, fuel lines and pump arrangements may differ to suit. It is unlikely to be a straightforward swap, but confirm with the breaker using both vehicles' engine codes and registrations to be certain. Do not assume fitment based on the shared X-Class bodyshell alone.

Trim level – Pure, Progressive or Power – does not affect fuel tank fitment on the X-Class; these trims reflect interior specification and equipment rather than mechanical differences. What matters is engine code, fuel type and gearbox type (manual or automatic), so focus on matching those details. You may receive a tank with different surface coatings or brackets depending on the donor vehicle's spec, but this has no bearing on whether it will fit and function correctly.

No – petrol and diesel fuel tanks are not interchangeable; beyond any physical differences, using the wrong tank creates a serious safety and contamination risk. The X-Class was sold in the UK predominantly as a diesel, so always confirm the fuel type of the donor vehicle matches yours before purchasing. Make this clear to the breaker when requesting a quote.

Year and badge name alone are not reliable enough for a mechanical component like a fuel tank, because different engine options within the same model year can have different ancillary configurations. Your engine code is stamped in the engine bay and also appears on your V5C logbook or can be obtained via a VIN check – it takes the guesswork out of matching. Provide this code to the breaker alongside your registration for the most accurate quote.
