Ford Fiesta Fuel Pump: Specs, Fitment & Common Faults

A simple priming-hum test and fuse check can save you from replacing a perfectly good fuel pump — worth trying first.

OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Bosch 0 580 454 094 / Hüco 133549

Accuracy note: Covers the Ford Fiesta (Mk7 2008-2017) 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 133549 (complete petrol feed unit / swirl-pot module with sender, observe assembly information); Hüco 133528 (complete petrol feed unit with sender); Hüco 133420 (complete petrol feed unit with sender); Hüco 133145 (complete petrol feed unit with sender); VDO 2803580316302 (petrol fuel feed unit, in-tank); Bosch 0 580 454 094 (bare in-tank electric pump, petrol); Delphi FE10300-12B1 (bare electric pump, petrol, metal housing, 120 mm long, 36.7 mm dia, supplied without seal or pressure sensor); Delphi FE10301-12B1 (bare electric pump, petrol, same dimensions) / Hüco 132704 (complete petrol feed unit with sender, observe assembly information); Astemo 2502704 (complete petrol feed unit with sender, the same Hitachi unit under its current brand); Hüco 133145 (complete petrol feed unit with sender); Hüco 133549 (complete petrol feed unit with sender); VDO 2803580316302 (petrol fuel feed unit); Delphi FE10300-12B1 (bare electric pump, petrol, metal housing, no seal or pressure sensor supplied); Pierburg 7.21440.51.0 (low-pressure electric pump, 0.3-0.4 bar, 2 pins, 12 V, 2 A, 133.5 mm long, 38 mm dia).
Types & variants	The petrol cars take a complete in-tank module with the level sender built in (Hüco and VDO units) or a bare pump cartridge (Bosch, Delphi) that is swapped into the existing housing. The 1.4 and 1.6 TDCi diesels use a high-pressure pump on the engine, so the in-tank side is a sender with at most a low-pressure lift pump; the Hella 8TF 358 148-621 is the only pre-supply pump listed. The 1.0 EcoBoost and 1.1 Ti-VCT petrols take a complete in-tank module with level sender (Hüco/Astemo/VDO), with the low-pressure in-tank pump feeding the engine-mounted high-pressure pump on the direct-injection EcoBoost. The 1.5 TDCi diesel has only a sender and lift arrangement in the tank, so the Pierburg low-pressure pump is the only diesel-side item.
Genuine (OE) numbers quoted	None quoted in catalogue listings — order a genuine unit against your VIN
Fitment notes	Petrol modules differ between the 1.25/1.4/1.6 Duratec and the 1.0 EcoBoost cars, so check the Hüco number against the engine and build date before ordering; a bare Bosch or Delphi cartridge can be fitted into the original housing if the sender and float still work, otherwise fit the complete unit. Removing the module needs the locking ring tool and a new seal, which are sold separately. The 2017-on car shares the 133145 and 133549 modules with the previous Fiesta, so the engine and build date decide which unit fits rather than the model year; a bare Delphi cartridge can be fitted into the original housing if the sender is good, otherwise replace the complete module. Fit a new tank seal with any module.

A Genuine Diagnostic Step Worth Trying Before Replacing the Pump — Ford Fiesta Fuel Pump

Before assuming the Ford Fiesta's fuel pump itself has failed, it's worth trying a simple, genuinely useful check: with the ignition turned to "on" but the engine not yet started, you should hear a faint 2-3 second hum from the rear of the car as the pump primes the fuel system. If you hear nothing at all, check the fuel pump fuse first — commonly fuse F56 in the passenger cabin fuse box on many Ford models, though always confirm your specific car's fuse layout — before assuming the pump itself needs replacing. A blown fuse is a considerably cheaper fix, and it's a genuinely common cause that gets overlooked in favour of jumping straight to pump replacement.

General wear symptoms worth knowing: 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 are the classic signs of a genuinely failing pump rather than a blown fuse or other simpler fault.

Ford Fiesta Fuel Pump: A Part That Fails at the Worst Possible Moments

This is one of the more inconveniently timed failures the Ford Fiesta 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.

Ford Fiesta Fuel Pump: What It Does

Delivering fuel from the tank to the engine at the correct pressure for combustion is the Ford Fiesta'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.

Ford Fiesta Fuel Pump: Generations & Engines: Fuel Pump Type

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.

Mk6 (2002–2008), 1.25/1.4/1.6 petrol & 1.4/1.6 TDCi 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
Mk7 (2008–2017), 1.25/1.4/1.6 Duratec petrol (pre-2012)	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
Mk7 (2012–2017), 1.0 EcoBoost petrol	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
Mk7 (2008–2017), 1.5/1.6 TDCi diesel	Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump
Mk7 ST (2013–2017), 1.6 EcoBoost petrol	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
Mk8 (2017–2023), 1.1 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
Mk8 (2017–2023), 1.0 EcoBoost petrol	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
Mk8 ST (2018–2023), 1.5 EcoBoost petrol	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
