Second Hand Mercedes-Benz CLA Fuel Pump

Yes, all CLA variants have a fuel pump, but the type differs by engine: petrol models use a low-pressure in-tank pump to feed the high-pressure direct-injection system, while diesel models have an in-tank lift pump working alongside a separate high-pressure pump on the engine. If you're searching for a used pump, make sure you specify whether yours is petrol or diesel, as these are completely different parts and not interchangeable.

The C117 and C118 are distinct generations with different underpinnings, so a fuel pump from the first generation is very unlikely to be a direct fit on the second generation even if the engine codes look similar. Always check the engine code from your V5 or a VIN check and confirm with the breaker against your registration before buying. Never assume fitment across a generation boundary.

The C117 received a facelift in 2016, and there can be ancillary or mounting differences mid-production that affect whether a pump from a pre-facelift car suits a post-facelift one. The engine code is your most reliable guide, but to be safe on any potential mid-run changes you should confirm compatibility with the breaker against your specific registration. Giving the breaker your full VIN removes most of the guesswork.

No, trim level has no bearing on fuel pump fitment whatsoever — the pump is determined by the engine, not the badge or interior specification. An AMG Line CLA with the M270 petrol engine needs the same pump as an SE with the identical engine code. Focus on supplying the breaker with your engine code and fuel type rather than your trim name.

The 200d and 220d both use variants of the OM651 diesel family in the C117 generation, but they may be calibrated or configured differently, and the fuel pump or lift pump specification can vary between them. The engine code stamped on your V5 or obtainable via a VIN check is the definitive reference here, and you should confirm interchangeability with the breaker directly. Do not rely on the badge alone when sourcing diesel fuel system components.

The CLA 180, 200, and 250 petrol models in the C117 generation all draw from the M270 or M133 engine family, so there is some overlap, but output differences and potential running changes mean the in-tank pump specification is not guaranteed to be identical across all variants. Always cross-reference the full engine code rather than assuming the shared platform means all pumps interchange. Confirm with the breaker against your registration before purchasing.
