|---|---|
| Types & variants | Same W176-family tank, so petrol complete modules with sender (VDO, Hüco 132737) stand against diesel feed units with sender (Hüco 132740 / Astemo 2502740 / Ridex 1382F0225). Vemo V30-09-0162 covers the all-wheel-drive (4Matic) tank, Metzger 2250678 (7 pins) and Topran 410 537 (6 pins, swirl pot, lever sensor) are budget modules, and febi 38095 / 10576 (M16 x 1.5 thread) and DT 2.05000 are hand-primer pre-supply pumps for the diesel fuel filter. |
| Genuine (OE) numbers quoted | A2464701494 (Meat & Doria 77853); 170429F500 (Meat & Doria 76416); 8941674933 (Meat & Doria 76041, carburettor pump, not applicable). |
| Fitment notes | Order by fuel and by front or 4Matic drive. The complete modules replace the sender; only the Hella 8TF 358 146-301 is a bare pump for refitting into the original housing with the sender kept. Hüco and Astemo units carry assembly instructions, and the Ridex diesel unit is the only one quoting a pressure figure. |
Mercedes-Benz GLA Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Mercedes-Benz GLA, few component failures are as inconveniently timed as this one — it has a habit of stranding drivers mid-journey rather than giving a clean warning while the car is safely parked. Knowing the early signs buys valuable time to get it sorted before that happens.
Mercedes-Benz GLA Fuel Pump: What It Does
The Mercedes-Benz GLA's fuel pump draws fuel from the tank and delivers it to the engine at the pressure required for proper combustion. Almost all modern versions sit inside the fuel tank itself, submerged in fuel, which is partly why access for replacement is more involved than the part's small size might suggest.

Confirmed: A Genuine Safety Recall Worth Checking Your Car Against — Mercedes-Benz GLA 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, particularly on a used car where you can't be certain a previous owner had this recall work completed, since the remedy was provided free of charge.
It's also genuinely worth knowing this recalled low-pressure pump is a separate component from the engine-mounted high-pressure fuel pump, located inside the fuel tank rather than on the engine itself — worth confirming which specific pump has actually failed before purchasing replacement parts.
