Ford Focus Mk3 Fuel Pump: Specs, Fitment & Common Faults
A documented 2014-specific housing crack, plus the genuine two-pump system on 2.0-litre models that can confuse standard fault code diagnosis.

A Part That Fails at the Worst Possible Moments
On the Ford Focus Mk3, 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.
OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Bosch 0 580 203 258 / Hüco 133506
| Fuel pumps / feed units (aftermarket) | Hüco 133506 (complete petrol feed unit with sender); Hüco 132720 (complete petrol feed unit with sender); Astemo 2503159 (complete petrol feed unit with sender); Hüco 133481 (complete petrol feed unit with sender, article number set by diagnostic tester); Hüco 133509 (complete petrol feed unit with sender); Hüco 133159 (complete petrol feed unit with sender); Bosch 0 580 203 258 (in-tank fuel feed unit); Bosch 0 580 203 119 (in-tank fuel feed unit) |
|---|---|
| Types & variants | Petrol cars (1.0 EcoBoost, 1.6 Ti-VCT, 1.6 EcoBoost, 2.0 GDI) take a complete swirl-pot module with the level sender, and there are several Hüco numbers because the EcoBoost direct-injection cars use a different low-pressure module from the port-injected 1.6. Diesel cars (1.5/1.6/2.0 TDCi) have a separate in-tank feed unit that is mainly a sender and swirl pot (Hüco 133128, Astemo 2503128, Ridex 1382F0586), with the high-pressure pump on the engine. |
| Genuine (OE) numbers quoted | Meat & Doria 77523E quotes 0580200064 (a Bosch number, OE equivalent); Meat & Doria 77347E quotes 172026141R (a Renault number, not relevant to the Focus); no Ford numbers quoted. |
| Fitment notes | Petrol and diesel modules are not interchangeable, and the petrol ones differ by engine and build date, so match the Hüco number to the VIN before ordering; the Bosch 0 580 203 xxx units are complete feed units, so there is no bare cartridge option listed and the whole module including sender is replaced. Fit a new seal and use the ring tool on removal. |

A Genuine, Specific Fault: Cracked Plastic Fuel Pump Housing on 2014 Models — Ford Focus Mk3 Fuel Pump
Some 2014-build Focus models had a documented manufacturing defect where the plastic housing of the in-tank fuel pump assembly could crack, leading to low fuel pressure and stalling. If you're looking at a Focus from this specific build year showing intermittent stalling or hesitation under acceleration, this is worth checking for specifically before assuming a more general fault. Beyond this specific issue, general fuel pump wear symptoms include engine sputtering or hesitation under acceleration, a longer-than-usual crank before starting, a noticeable whining or buzzing noise from the rear of the car near the fuel tank, and stalling at low speeds or idle — a check engine light showing code P0087 (fuel rail pressure too low) is a common diagnostic trigger for any of these underlying causes.
On 2.0-litre direct-injection Focus models specifically, there are genuinely two separate fuel pumps working together: a low-pressure pump inside the tank, and a separate high-pressure pump mounted on the engine. A P0087 code can be triggered by either one failing — if the low-pressure in-tank pump is struggling, it starves the high-pressure pump of adequate supply, producing the same fault code as a genuine high-pressure pump failure. A scan tool showing actual versus desired fuel rail pressure, with low pressure specifically at idle, points toward the in-tank pump as the more likely cause.
Ford Focus Mk3 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 Ford Focus Mk3 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.
Ford Focus Mk3 Fuel Pump: Generations & Engines: Fuel Pump Type
| Mk1 (1998–2004), Zetec/CVH 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 |
|---|---|
| Mk1 (1998–2004), Duratec petrol & ST170/RS | 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 |
| Mk1/Mk2 (1998–2011), TDCi diesel | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| Mk2 (2005–2011), 1.8/2.0 non-turbo 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 |
| Mk2 ST225/RS (2005–2010), 2.5 five-cylinder turbo | 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 |
| Mk3 (2011–2018), 1.6 Ti-VCT 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 |
| Mk3 (2012–2018), 1.0 EcoBoost petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Mk3 (2011–2018), TDCi diesel | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| Mk3 ST (2012–2018) & RS (2016–2018) | 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 |
| Mk4 (Sept 2018–Dec 2019 only), 1.0 EcoBoost petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Mk4 (from Dec 2019), 1.0 EcoBoost petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Mk4 (2018–2025), 1.5 EcoBoost petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Mk4 (2018–2025), EcoBlue diesel | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
