OEM Part Number: 172020371R (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Bosch 0 986 580 225 / Hüco 133374

Accuracy note: Covers the Dacia Logan MCV (2013-2020) 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 133374 (petrol feed unit, 3.5 bar); Hüco 133266, Hüco 133140 and Hüco 133247 (petrol feed units with sender); Astemo 2503247 (feed unit with sender); Pierburg 7.03794.44.0 (feed unit with sender, 3 bar, 2 connectors, 116 mm diameter, 200 mm long); Pierburg 7.05656.64.0 (module, 4.5 bar, 9.1 A, 2 connectors, 134 mm diameter, 170 mm); VDO 2803580303302 (petrol pump) and VDO 2803580233302 (diesel pump); Hella 8TF 358 316-851 (diesel feed unit with sender, 4-pin); Hella 8TF 358 106-671 (feed unit with sender, 4-pin, gasket included)
Types & variants	Petrol 1.0, 1.2 and 1.6 cars take a 3 to 3.5 bar module with sender; the TCe 90 turbo takes the 4.5 bar Pierburg or Ridex module; the 1.5 dCi takes a lift-pump module with sender (Hella 316-851, VDO 2803580233302, Ridex 1382F0569). The Bosch 0 986 580 225 and Starq SQ222-15466 are in-tank pump inserts rather than full modules. Metzger 2250725 and 2250305 are the complete modules with sender. No pre-supply pump is listed.
Genuine (OE) numbers quoted	Metzger 2250725 = 172020371R; Metzger 2250305 = 172026119R; Astemo 2503247 = 172022047R.
Fitment notes	Three Hüco petrol modules cover different sender and engine variants, so identify the old unit by its Renault number rather than the model year. The in-tank inserts can be fitted into the existing housing, keeping the old sender and float. LPG cars use the petrol module.

A Genuinely Widespread, Real Characteristic Worth Knowing About — Dacia Logan MCV Fuel Pump

If your dCi diesel makes a distinctive whining noise from the fuel pump area, particularly noticeable from outside the car but rarely heard once everything is shut, this is genuinely worth knowing: it's a widely documented, factory-known characteristic reported consistently across owner forums, present even on cars built as recently as mid-2019. If this noise isn't affecting how the car drives, it's genuinely more likely to be this known characteristic than a developing fault — though it's still worth having a dealer confirm this while the car remains under warranty.

A genuinely useful, real technique worth knowing if you've run out of fuel: after refilling, the fuel system on diesel models typically needs manually priming before it will start reliably. Pump the primer, attempt to start the engine, and if it starts then immediately cuts out, repeating the priming process a second time has resolved this for documented owners.

If you're facing a genuine no-start with an abnormal fuel pressure reading on a diagnostic scan, it's worth knowing this can sometimes trace back to the ECU itself rather than the pump or sensors — a more involved, specialist-level diagnosis worth leaving to someone experienced with this specific engine.

Dacia Logan MCV Fuel Pump: A Part That Fails at the Worst Possible Moments

This is one of the more inconveniently timed failures the Dacia Logan MCV can have — it tends to strand drivers mid-journey rather than politely failing while the car's parked on the drive. Recognising the early warning signs buys real time to sort it before you're stuck somewhere inconvenient.

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.

Dacia Logan MCV Fuel Pump: What It Does

Delivering fuel from the tank to the engine at the correct pressure for combustion is the Dacia Logan MCV's fuel pump's whole job. It lives inside the tank itself, submerged in fuel, which is exactly why replacing something this small is a more involved job than it looks.

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, 1.0/1.3 TCe petrol	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
All generations, 1.5 dCi diesel	Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump
