Cheap Mercedes-Benz GLC Fuel Tank

The GLC (X253) ran from 2015 to 2022, with a facelift in 2019, so a 2016 donor and a 2019 car sit either side of that facelift boundary. Within the same engine code and fuel type the basic tank shape may well be shared, but mounting points, sender unit connections, and filler neck routing can change across a facelift year, so you should confirm directly with the breaker against your exact registration before buying.

No — petrol and diesel fuel tanks are not interchangeable; the tank, filler neck, and fuel system components are designed around the specific fuel type, and fitting the wrong one would be unsafe. Always make sure the donor vehicle's fuel type matches your own, and quote your engine code to the breaker so they can verify the correct unit.

Trim level (Sport, AMG Line, Executive, and similar GLC grades) does not affect fuel tank fitment — the tank is a mechanical component determined by engine code, fuel type, and model year, not the trim specification. A tank from any trim should be compatible provided the engine code, fuel type, and year range match, so don't let trim badging influence your search.

The GLC X253 was facelifted in 2019, so a 2017 car is pre-facelift and your 2020 is post-facelift, and that boundary is exactly where fitment becomes uncertain for ancillary details like mounting brackets, breather pipes, and sender unit connectors. The core tank may be dimensionally similar, but you should confirm with the breaker against both registrations rather than assume it will drop straight in.

The most important information is your engine code (found on your V5C or via a VIN check), your fuel type, your model year, and your full registration so the breaker can cross-reference their stock accurately. The engine code matters more than the badge or trim level for mechanical parts like the fuel tank, and supplying it upfront will get you a more reliable answer and a faster quote.

The 220d and 250d are different engine variants, and while they may share the same physical tank depending on year, you should not assume fitment purely from the badge — quote your actual engine code to the breaker rather than relying on the displacement figure in the model name. The breaker can then match the donor engine code to yours and confirm whether the tank, sender unit, and fittings are compatible with your specific car.
