OEM Part Number: A2464701494 (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Bosch 0 580 454 093 / Hüco 132737

Accuracy note: Covers the Mercedes-Benz CLA (C117 2013-2019) as listed in the UK aftermarket catalogues. In-tank fuel pumps are sold two ways: as a complete feed unit (the pump in its swirl pot with the fuel-level sender and float) or as a bare pump that is fitted into the old housing, and petrol and diesel versions are not interchangeable — most diesels have only a low-pressure lift pump in the tank, with the high-pressure pump on the engine. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; genuine numbers are shown only where a listing quotes one. Check fuel type, the plug pin count and whether your car has one sender or two (saddle tanks on 4x4 and some larger cars) against your VIN before ordering.

Fuel pumps / feed units (aftermarket)	VDO 2803580306302 (complete feed unit, petrol, with reserve sensor); Hüco 132737 (complete feed unit with sender, petrol); Hüco 133155 (complete feed unit with sender, petrol); Astemo 2503155 (complete feed unit with sender, petrol); Hüco 132740 (complete feed unit with sender, diesel); Astemo 2502740 (complete feed unit with sender, diesel); Hella 8TF 358 146-301 (bare in-tank pump, qualified fitting required); Bosch 0 580 454 093 (bare in-tank pump).
Types & variants	The C117 shares the W176 A-Class tank, so the same split applies: petrol complete modules with sender (VDO, Hüco 132737 / 133155, Astemo 2503155) against diesel low-pressure feed units with sender (Hüco 132740 / Astemo 2502740). Vemo V30-09-0162 is the all-wheel-drive (4Matic) variant, Metzger 2250678 (7 pins) and Topran 410 537 (6 pins, swirl pot, lever sensor) are budget modules, Ridex 1382F0121 is a mechanical gear-type diesel feed pump and DT 2.05002 a hand-primer pre-supply pump.
Genuine (OE) numbers quoted	A2464701494 (Meat & Doria 77853); 8941674933 (Meat & Doria 76041, carburettor pump, not applicable). No Mercedes numbers quoted against the main modules.
Fitment notes	Order by fuel and by drive. The complete modules replace the gauge sender along with the pump; the Bosch and Hella bare pumps refit into the original housing with the sender retained, which suits a petrol car whose gauge still works. Hüco and Astemo units carry assembly instructions that must be followed.

Mercedes-Benz CLA Fuel Pump: A Part That Fails at the Worst Possible Moments

On the Mercedes-Benz CLA, there's rarely a convenient time for this to fail — it tends to strike mid-journey rather than while the car's sitting safely on the drive. Knowing what the early symptoms look like buys valuable time to get ahead of it.

Before you buy: fuel pump specifications vary by engine size and fuel type, and petrol/diesel versions are never interchangeable. Always confirm against your VIN before ordering.

Mercedes-Benz CLA Fuel Pump: What It Does

The job here is simple in principle — draw fuel from the tank, deliver it to the engine at the right pressure — but the Mercedes-Benz CLA's fuel pump sits submerged inside the tank, which makes physical access for replacement far more involved than the small part itself implies.

Accuracy note: these are documented patterns by generation and engine family, not a substitute for confirming your exact engine code — always verify against your V5C before ordering, since petrol and diesel pumps are never interchangeable.

Confirmed: A Genuine Safety Recall Worth Checking Your Car Against — Mercedes-Benz CLA Fuel Pump

This is genuinely important to check directly: a confirmed recall covering many 2021-2023 models directly addresses the in-tank low-pressure fuel pump, where the pump's impeller can genuinely deform due to a manufacturing defect. Once deformed, the impeller can come into contact with its housing, creating resistance that shuts the pump down entirely and causes the engine to stall — a genuine safety concern.

A genuinely useful, distinctive clue worth knowing: before the pump ceases operation entirely, a warning message may appear within the instrument cluster, and the engine may begin running roughly.

It's also genuinely worth knowing this recalled low-pressure pump is a separate component from the engine-mounted high-pressure fuel pump, worth confirming which specific pump has actually failed before purchasing replacement parts.
