OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Bosch 0 580 454 094 / Hüco 133528

Accuracy note: Covers the Mazda 2 (DJ 2014-) 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 133528 (complete in-tank feed unit with fuel sender, petrol, assembly information must be observed); Bosch 0 580 454 094 (bare in-tank pump, electric); Pierburg 7.21440.51.0 (pre-supply / lift pump, 0.3-0.4 bar, 2 connectors, 12 V 2 A, 38 mm body, 133.5 mm long, 8 mm in and out); Engitech ENT100053 (bare in-tank pump, 4 bar / 125 l/h, 2 connectors, 54.5 mm body, 188 mm long); Ridex 458F0005 (bare in-tank pump, 3.3 bar / 100 l/h, 38 mm body, 115 mm long, 10 mm in / 9 mm out); Ridex 458F0040 (bare in-tank pump, 3.4 bar / 100 l/h, 2 connectors); Meat & Doria 76416 (bare in-tank pump, 3 bar / 95 l/h).
Types & variants	The petrol SKYACTIV-G has a complete swirl-pot module with sender (Hüco 133528) plus bare 38 mm pumps for fitting into the old housing. The 1.5 D diesel has no high-pressure module; it uses a low-pressure in-tank lift pump, which is where the 0.3-0.4 bar Pierburg 7.21440.51.0 and the similar Ridex 458F0008 belong. No early/late sender split is shown.
Genuine (OE) numbers quoted	170429F500 (Meat & Doria 76416 / Hoffer 7506416); 3111137300 (Hoffer 7506385 / Meat & Doria 76385); 142504 (Kamoka 8410016); 8450008680 (Kamoka 8410005); 8941674933 (Meat & Doria 76041, carburettor pump, not applicable). No Mazda numbers are quoted.
Fitment notes	Choose by fuel first: the petrol car takes a 3-4 bar pump or the complete Hüco module, the diesel takes a sub-1 bar lift pump. A bare pump can be fitted into the original module while the sender and float are kept; only the Hüco unit replaces the sender as well.

Confirmed: A Genuine, Serious UK Safety Recall Worth Checking Your VIN Against — Mazda 2 Fuel Pump

This is genuinely worth checking directly against your specific car: Mazda issued a UK safety recall (reference R/2021/435) covering models manufactured between October 2017 and September 2019, for a genuine fault in the low-pressure fuel pump manufactured by Denso — the plastic impeller inside can crack and deform, potentially causing the pump to fail and the engine to stall while driving or fail to start. Around 27,000 UK-registered vehicles were covered, with the fix being a full replacement pump fitted free of charge.

A genuinely useful, real diagnostic point worth knowing: a pre-failure pump can produce intermittent stalling that a basic roadside pressure test doesn't catch — one documented case saw a breakdown recovery service find no fault via pressure testing, despite the car repeatedly cutting out, with the recall replacement ultimately resolving it completely.

It's also genuinely worth knowing that dealers commonly ask that the fuel tank be no more than a quarter full before the appointment, and that some documented cases saw a noticeable amount of fuel go missing during the process. An evaporative emissions fault code appearing shortly after this specific recall work has also been documented in some cases.

Mazda 2 Fuel Pump: A Part That Fails at the Worst Possible Moments

On the Mazda 2, this particular failure has a knack for terrible timing, stranding drivers mid-journey instead of giving fair warning while the car's parked up safely. Spotting the early signs early enough is what stands between a routine fix and a roadside breakdown.

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.

Mazda 2 Fuel Pump: What It Does

Getting fuel from tank to engine at the correct combustion pressure is down to the fuel pump, and on the Mazda 2 that pump sits inside the tank, submerged in fuel. That location is exactly why swapping out such a small part is rarely a quick job.
