Ford S-Max Fuel Pump: Specs, Fitment & Common Faults

A simple priming-hum test and fuse check can rule out a much cheaper cause before assuming pump failure.

OEM Part Number: FV41-9H307-AA (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Bosch 0 580 203 264 / Hüco 133245

Accuracy note: Covers the Ford S-Max (2015-) 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)	Bosch 0 580 203 264 (in-tank fuel feed unit); Bosch 0 580 204 345 (in-tank fuel feed unit); Hüco 133245 (fuel feed unit, with sender); Hüco 133251 (fuel feed unit, petrol, with sender); VDO 2803580198302 (fuel feed unit, petrol); Ridex 1382F0052 (fuel feed unit, petrol, 3.5 bar / 170 l/h, 5 pins, with sender); Hella 8TF 358 148-621 (pre-supply pump, 3.5 bar, 4.5 l/min, 2 pins); ERA 775080A (feed unit, 4 bar / 60 l/h, 5 pins, pump no. F7AU9350DB).
Types & variants	The S-Max shares its tank module with the Galaxy Mk3. Petrol EcoBoost cars take a 3.5 bar feed unit with sender (Ridex 1382F0052, Hüco 133251, VDO 2803580198302); the two Bosch feed units are listed without a fuel type and cover the module fitted to the TDCi and EcoBlue diesels and petrol cars respectively. No bare pump motor is offered for this generation.
Genuine (OE) numbers quoted	FV41-9H307-AA (Fispa 721012, listed as genuine quality); 1565527 (Meat & Doria 77838); pump no. F7AU9350DB (ERA 775080A).
Fitment notes	Diesels use a low-pressure lift module, so a petrol unit cannot be substituted. Every listed unit is a complete module with sender; match the pin count (5 pins on the petrol Ridex and ERA units) and the OE number stamped on the old module, and renew the tank seal ring at the same time.

Before You Replace the Pump, Try This Simple Test

Before assuming the Ford S-Max'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 S-Max Fuel Pump: A Part That Fails at the Worst Possible Moments

On the Ford S-Max, few component failures are as inconveniently timed as this one — it has a habit of stranding drivers mid-journey rather than giving a clean warning while the car is safely parked. Knowing the early signs buys valuable time to get it sorted before that happens.

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 S-Max Fuel Pump: What It Does

The Ford S-Max's fuel pump draws fuel from the tank and delivers it to the engine at the pressure required for proper combustion. Almost all modern versions sit inside the fuel tank itself, submerged in fuel, which is partly why access for replacement is more involved than the part's small size might suggest.

Ford S-Max 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.

Mk1 (2006–2015), 2.0 TDCi diesel	Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump
Mk1, 2.0/2.5 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 (2015–2022), 1.5/2.0 EcoBoost petrol & 2.0 EcoBlue 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
