OEM Part Number: 52051093 (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Bosch 0 986 580 229 / Hüco 133369

Accuracy note: Covers the Fiat 500X (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 0 986 580 229, Bosch 0 580 200 008 and Bosch 0 580 203 451 (electric in-tank pumps); Hüco 133369 (petrol feed unit, 3.5 bar); Hüco 133263, Hüco 132745 and Hüco 133410 (diesel feed units with sender); VDO A2C59511710 (diesel tank pump with lever sender, 2.6 bar); Hella 8TF 358 305-061 and Hella 8TF 358 305-071 (diesel feed units with sender, 4-pin, gaskets included); Delphi FG2391-12B1 (feed unit without gasket or pressure sensor, no sender); Meat & Doria 77551 (feed unit, 5 bar); Meat & Doria 77760 (electric pump, 5.3 bar)
Types & variants	The 1.0 and 1.3 FireFly turbo petrols and the 1.4 MultiAir are direct- or port-injected, with the 5 to 5.3 bar Meat & Doria units covering the higher-pressure applications and the 3.5 to 4 bar Hüco and Ridex units the rest; the 1.3, 1.6 and 2.0 Multijet diesels take a 2.6 bar lift-pump module with lever sender. Metzger 2250694 is a complete in-tank module with sender. The Bosch references are pump inserts. No pre-supply pump is listed.
Genuine (OE) numbers quoted	Meat & Doria 77551 = 52051093; Meat & Doria 77760 = K68439550AA; Hoffer 7507110E = 51829566.
Fitment notes	The three OE numbers separate the module families, so read the number on the old unit before ordering. Diesel modules carry the lever sender; the Delphi unit is sold without one. Bosch inserts fit into the old housing.

A Genuinely Important Habit Worth Building: Checking for Open Recalls — Fiat 500X Fuel Pump

Fiat has issued multiple genuine, confirmed fuel delivery recalls across its small car range, including a chafing fuel pipe issue on certain Panda builds and separate recalls covering a faulty fuel pump protection bracket and faulty fuel manifolds on the 500. It's genuinely worth checking your specific VIN against Fiat's official recall database directly, particularly on a used car where you can't be certain a previous owner had any relevant recall work completed.

A genuinely important safety instruction worth knowing: if you ever notice a smell of fuel while driving, or spot damp patches underneath the car that could be fuel, it's genuinely worth stopping and having the car inspected before continuing.

It's also genuinely worth knowing a useful diagnostic distinction: a sudden whiff of fuel while driving is commonly caused by faulty fuel injector seals specifically, rather than the fuel pump itself.

Fiat 500X Fuel Pump: A Part That Fails at the Worst Possible Moments

Rather than failing conveniently while parked, this component on the Fiat 500X tends to give up mid-journey, which is about the worst possible moment. Learning to recognise the early symptoms is the best defence against being caught out.

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.

Fiat 500X Fuel Pump: What It Does

The Fiat 500X's fuel pump function — pulling fuel from the tank and pressurising it for the engine — is straightforward, but its usual location isn't: it sits submerged inside the tank itself, which is precisely why access for replacement is more work than the part's size suggests.

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.
