OEM Part Number: A2464701494 (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Bosch 0 580 454 093 / Hüco 132737
| Fuel pumps / feed units (aftermarket) | Hüco 132737 (complete feed unit with sender, petrol); Hüco 133411 (complete feed unit with sender, petrol); Hüco 133525 (complete feed unit with sender, petrol); Hüco 133155 (complete feed unit with sender, petrol); VDO 2803580306302 (complete feed unit, petrol, with reserve sensor); Hüco 132740 (complete feed unit with sender, diesel); Astemo 2502740 (complete feed unit with sender, diesel); Hella 8TF 358 146-101 (complete feed unit with sender, 4 pins, qualified fitting required) |
|---|---|
| Types & variants | Petrol and diesel W176 units are separate complete swirl-pot modules with sender. The petrol side has four Hüco modules plus the VDO original-equipment pattern, split by engine (1.6 M270 against 2.0 M270 and A 45) and by front or 4Matic tank; the diesel side (1.5 OM607 and 1.8/2.1 OM651) uses the Hüco 132740 / Astemo 2502740 unit, which is a low-pressure feed unit with sender rather than a high-pressure pump. Metzger 2250678 (7 pins, with sender) and Topran 410 537 (6 pins, swirl pot and lever sensor) are the budget equivalents, and Maxgear 43-0186 is a mechanical gear-type diesel feed pump. |
| Genuine (OE) numbers quoted | A2464701494 (Meat & Doria 77853); 170429F500 (Hoffer 7506416). No other Mercedes numbers quoted. |
| Fitment notes | Order by fuel and by drive (front or 4Matic), as the modules are not interchangeable. The complete modules replace the sender with the pump; only the Bosch 0 580 454 093 and Bosch 0 580 203 00Y are bare pumps for refitting into the original housing. Hüco units carry assembly instructions that must be followed. |
Mercedes-Benz A-Class Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Mercedes-Benz A-Class, few faults pick a worse moment to happen than this one, which has a habit of leaving drivers stranded mid-journey rather than failing safely at home. Catching the early signs gives you a genuine head start before that happens to you.
Mercedes-Benz A-Class Fuel Pump: What It Does
On the Mercedes-Benz A-Class, fuel reaches the engine at the pressure combustion needs thanks to the fuel pump, which draws it straight from the tank. It sits submerged inside the tank itself, and that positioning is a big part of why replacement takes more effort than the part's size would suggest.
Mercedes-Benz A-Class Fuel Pump: Generations & Engines: Fuel Pump Type
| W176 (2012–2018) & W176 A45 AMG, all petrol (M270/M133) | Petrol: typically a single in-tank low-pressure pump; some later or higher-output variants may add a separate engine-mounted high-pressure pump for direct injection — confirm your exact engine |
|---|---|
| W176/W177, all diesel (OM651/OM654/OM608) | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| W177 (2018–present), all petrol (M282/M260) | Petrol: typically a single in-tank low-pressure pump; some later or higher-output variants may add a separate engine-mounted high-pressure pump for direct injection — confirm your exact engine |
| W177 A35 AMG & A45 S AMG (2019–present), 2.0 turbo (M139) | Petrol: typically a single in-tank low-pressure pump; some later or higher-output variants may add a separate engine-mounted high-pressure pump for direct injection — confirm your exact engine |

Confirmed: A Genuine Safety Recall Worth Checking Your Car Against — Mercedes-Benz A-Class 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, since this can happen suddenly while driving. Worth checking your specific VIN against the official recall register directly.
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.
