Mercedes-Benz GLC Fuel Pump: Specs, Fitment & Common Faults

Confirmed: a genuine safety recall addresses water leaking into the spare tyre well and damaging the fuel pump control module — worth checking for moisture there before assuming the pump itself has failed.

OEM Part Number: 205 470 1694 (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Hüco 132718 / Pierburg 7.03794.46.0

Accuracy note: Covers the Mercedes-Benz GLC (X253 2015-) 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)	Hüco 132718 (complete feed unit, petrol, assembly information must be observed); Pierburg 7.03794.46.0 (complete feed unit, 3 bar, 1 connector, 129 mm flange, 230 mm); Pierburg 7.03794.47.0 (second tank-side unit, 0.5 bar, 2 connectors, 130 mm flange, 164 mm); Metzger 2250705 (feed unit, right-hand tank side, 11 pins, 1 connector); Metzger 2250626 (feed unit without sender, 8 pins); Delphi FG2776-12B1 (complete feed unit, without pressure sensor, without seal); Vemo V30-09-0140 (feed unit without sender, diesel, 8 pins); Hella 8TF 358 146-301 (bare in-tank pump, 15 mm inlet, 8 mm outlet, mounting and connector parts).
Types & variants	The GLC shares the W205 saddle tank: a 3 bar pump-side unit, a 0.5 bar passive-side unit and separate 8-pin no-sender and 11-pin sender variants (Stark SKFU-0410389 and Ridex 1382F0389 are the budget 8-pin units, Topran 410 945 the budget 11-pin unit). Ridex 1382F0121 is a mechanical gear-type diesel feed pump; febi 38095 (M16 x 1.5, 85 mm) and DT 2.05000 are hand-primer pre-supply pumps; Pierburg 7.21088.62.0 (0.2 bar / 120 l/h, with strainer) is a low-pressure lift pump.
Genuine (OE) numbers quoted	205 470 1694 (Trucktec 02.38.166); A2054701594 (Metzger 2250705); 205 470 4900 (Trucktec 02.38.145); 170429F500 (Meat & Doria 76416); recommended accessories A2055400017 and A0259971845 (Metzger 2250626).
Fitment notes	Establish which side of the saddle tank is at fault and whether the sender is wanted, then order by fuel. There is no bare drop-in pump for the main module beyond the generic Hella; the Delphi and Pierburg units ship without the tank seal.

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

On the Mercedes-Benz GLC, 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.

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 GLC Fuel Pump: What It Does

The Mercedes-Benz GLC'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.

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.

All generations, M264 petrol & OM654 diesel	Spans both diesel (in-tank lift pump plus an engine-mounted high-pressure pump) and petrol (in-tank low-pressure pump, plus a separate high-pressure pump if direct-injection) variants — confirm your exact engine before ordering

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

If a fuel delivery fault has appeared, this is genuinely worth checking directly before replacing any parts: a confirmed recall affecting many related SUV models addresses water leaking into the spare tyre well and damaging the fuel pump control module located there, the electronic unit responsible for regulating the in-tank fuel pump. Worth checking the spare tyre well specifically for any signs of moisture, damp carpet, or standing water before assuming the pump itself has failed, since water damage to this control module can produce very similar symptoms to a genuine pump failure. The recall remedy involves a dealer installing a drain plug and replacing the control unit if it's been damaged by water, worth checking your specific VIN against the official recall register directly.

A genuinely important, distinctive clarification worth knowing: these vehicles have three separate components that can each cause fuel delivery problems — the fuel pump control module, the low-pressure pump inside the tank, and the high-pressure pump mounted on the engine — worth confirming which specific component has actually failed before purchasing replacement parts, since misdiagnosing this can prove genuinely expensive.

It's also genuinely worth knowing that a worn cam follower can specifically prevent the high-pressure fuel pump from maintaining the required rail pressure, worth replacing this component at the same time as the pump itself if that specific pump is genuinely being replaced.
