OEM Part Number: 2322123010 (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Bosch 0 986 AG1 303 / Delphi FE0670-12B1

Accuracy note: Covers the Toyota Prius (2016-) 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 0 986 AG1 303 (bare in-tank pump, petrol); Bosch 0 580 454 094 (bare in-tank pump); Delphi FE0670-12B1 (bare in-tank pump, petrol, metal housing); Meat & Doria 76393 (supply module, 3.5 bar / 60 l/h, OE 2322123010); Magneti Marelli 313011300038 (bare in-tank pump, 3 bar / 90 l/h, 12 V); ERA 770162A (bare in-tank pump, 3.2 bar / 120 l/h, 2-pin, 38 mm body); Starq SQ222-12322 (bare in-tank pump, 3 bar / 90 l/h, 38 mm body, 5 A, with mounting kit and connector parts)
Types & variants	Bare in-tank cartridges throughout; the Meat & Doria 76393 is the one item quoting a Toyota OE number and its 60 l/h rating suits the low-demand hybrid engine. No complete module with sender is offered. Petrol hybrid only.
Genuine (OE) numbers quoted	2322123010 (Meat & Doria 76393); 170429F500 (Meat & Doria 76416, Hoffer 7506416); 3111137300 (Meat & Doria 76385, Hoffer 7506385); 142504 (Kamoka 8410016); 8450008680 (Kamoka 8410005)
Fitment notes	Petrol hybrid only. The cartridge is fitted into the original tank module and keeps the level sender; the Prius tank sits low and access is through the rear seat base. Toyota 23221-23010 is the genuine pump reference the Meat & Doria 76393 is cross-listed to.

A Genuinely Important Habit Worth Building: Checking for Open Recalls — Toyota Prius Fuel Pump

Toyota and Lexus have issued multiple genuine, official fuel pump recalls across various models since around 2020, related to an underlying pump design issue that can cause worn or damaged components inside the high-pressure fuel pump, with a real risk of fuel leak or engine stalling in the worst cases. It's genuinely worth checking your specific VIN against Toyota's official recall checker directly, rather than assuming a notice would definitely have reached you, particularly on a used car or one bought from a previous owner who may have moved address.

Worth knowing if you're buying used: it's genuinely worth asking a seller directly whether any relevant recall work has been completed, and requesting to see documented evidence in the service history rather than simply taking their word for it.

It's also worth knowing that a clean check for one specific recall doesn't guarantee there are no other open recalls affecting your exact build — checking the full list against your VIN rather than a single recall in isolation is worth doing periodically, particularly after buying a used car.

Toyota Prius Fuel Pump: A Part That Fails at the Worst Possible Moments

On the Toyota Prius, 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.

Toyota Prius Fuel Pump: What It Does

The Toyota Prius'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.

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.

All generations, 1.5/1.8 Atkinson-cycle hybrid 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 — the hybrid system doesn't change this; the combustion engine still needs its own fuel pump
