OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Bosch 0 580 454 094 / Pierburg 7.21440.51.0
| Fuel pumps / feed units (aftermarket) | Hella 8TF 358 306-891 (complete in-tank feed unit with fuel sender, 4 pins, qualified fitting required); Delphi FG2493-12B1 (complete feed unit, 226 mm long, without pressure sensor, without gasket); ERA 775490A (complete feed unit, 3 bar / 100 l/h, 4 connectors); Bosch 0 580 454 094 (bare in-tank pump); Delphi FE0429-12B1 (bare in-tank pump, petrol, 113 mm, metal housing, without pressure sensor); Pierburg 7.21440.51.0 (pre-supply / lift pump, 0.3-0.4 bar, 2 connectors, 12 V 2 A, 133.5 mm, for the diesel); Meat & Doria 76416 (bare in-tank pump, 3 bar / 95 l/h). |
|---|---|
| Types & variants | Three complete modules (Hella, Delphi FG2493, ERA 775490A at 3 bar / 100 l/h) cover the SKYACTIV-G petrol with sender included, and bare pumps cover a motor-only repair. The 2.2 D diesel has no high-pressure in-tank module and takes a low-pressure lift pump, which is where the Pierburg 7.21440.51.0 and Ridex 458F0008 sit. |
| Genuine (OE) numbers quoted | 142504 (Kamoka 8410016); 3111137300 (Meat & Doria 76385 / Hoffer 7506385); 170429F500 (Meat & Doria 76416); 8941674933 (Meat & Doria 76041, carburettor pump, not applicable). No Mazda numbers are quoted. |
| Fitment notes | Petrol modules and diesel lift pumps are different parts and must be ordered by fuel. The Hella module and the ERA unit include the fuel level sender; the Delphi FG2493-12B1 is supplied without a pressure sensor and without the tank seal, so order the gasket separately. A bare pump can be fitted into the original petrol module while the Mazda sender is retained. |
Confirmed: A Genuine, Serious UK Safety Recall Worth Checking Your VIN Against — Mazda 6 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.
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 6 Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Mazda 6, 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.

Mazda 6 Fuel Pump: What It Does
On the Mazda 6, 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.
Mazda 6 Fuel Pump: Generations & Engines: Fuel Pump Type
| GG/GY (2002–2008), older MZR petrol | 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 |
|---|---|
| GH (2007–2013), MZR petrol & older 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 |
| GJ/GL (2012–present), SkyActiv-G petrol & SkyActiv-D 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 |
