Citroen C4 Fuel Pump: Specs, Fitment & Common Faults

A genuine, confirmed safety recall covers a fuel leak fire risk — plus a real fitment trap between Delphi and Bosch pump variants worth checking before ordering.

Generation covered: this guide is for the current C4 (launched 2021, facelifted 2024), with particular focus on 2021–2023 registered examples now old enough for parts to be a common search. Check your logbook or VIN if you're unsure which generation you have.

Confirmed: A Genuine Safety Recall — A Fuel Leak Fire Risk

This is genuinely worth checking against your VIN before anything else: Citroën confirmed a recall covering a fuel leak risk in the high-pressure hose between the high-pressure pump and the fuel rail, caused by loose nuts — this leak has been confirmed capable of causing a fire. This is a genuine, serious safety recall rather than a routine reliability issue, and confirming this work has been completed is a real priority if you're looking at a used C4 or considering any work near the fuel rail yourself.

A genuinely specific fitment trap worth knowing before ordering a replacement pump: high-pressure fuel pumps on this platform were supplied by two different manufacturers — Delphi and Bosch — and these aren't necessarily directly interchangeable between different engine variants (8-valve versus 16-valve versions of the same displacement, for instance). One documented case saw an owner order a pump from an online used parts seller, only to receive a Bosch unit when their car genuinely needed the Delphi version, discovering the mismatch only once the old pump was already removed. Always confirm the exact manufacturer and part reference matches your specific engine code via your VIN before ordering, rather than assuming a pump listed for your model generally will be correct.

If you're chasing a genuine fuel pressure fault rather than a leak, real fault codes worth knowing include P0087 (fuel rail pressure too low) and P0088 (fuel rail pressure too high) — worth mentioning to whoever is diagnosing the car, since these point toward different specific causes within the fuel delivery system.

Citroen C4 Fuel Pump: A Part That Fails at the Worst Possible Moments

On the Citroen C4, 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.

OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Bosch 0 986 580 217 / Astemo 2503338

Accuracy note: Covers the Citroen C4 (III 2020 on) 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 0 986 580 217 (electric in-tank feed unit); Bosch 0 986 580 215 (electric in-tank pump); Bosch 0 986 580 421 (electric in-tank pump); Hella 8TF 358 303-111 (complete feed unit, 3 bar, 4-pin, 12 V); Hella 8TF 358 305-331 (electric feed unit with sender, petrol, 4-pin); Hella 8TF 358 106-181 (electric feed unit with sender, 4-pin); Astemo 2503338 (in-tank electric pump, diesel, 2.5 bar); Delphi FG2701-12B1 (fuel supply module, without pressure sensor, supplied without seal)
Types & variants	Petrol 1.2 PureTech cars take a pressurised feed unit with a built-in sender (Hella 8TF 358 305-331, Hella 303-111, ERA 775443A, Ridex 1382F0022). The 1.5 and 1.6 BlueHDi diesels take a low-pressure lift module, which is why the Astemo 2503338 at 2.5 bar and the Ridex 1382F0342 and 1382F0016 are marked diesel. The Bosch 0 986 580 references are complete in-tank units. A Metzger 2250717 swirl-pot module without sender, for cars with the fuel filter inside the tank and no parking heater, sits alongside the full modules. The ë-C4 electric car has no fuel pump.
Genuine (OE) numbers quoted	15 25.N7 (Kamoka 8400046); 1400209180 (Kamoka 8400076); 1525KG (Kamoka 8400078); 1525Q5 (Kamoka 8400075); none quoted against the Bosch, Hella, Astemo, Delphi or ERA references.
Fitment notes	Petrol and diesel modules are not interchangeable because the diesel unit is a 2.5 to 3.5 bar lift pump feeding the high-pressure pump on the engine, while the petrol unit supplies the injection rail directly. Modules supplied without the sender keep the original float arm, so fuel gauge calibration is unaffected; full modules replace the sender too. Only the Ridex and Hella listings state the pin count (4), so match the connector before ordering.

The 1.2 PureTech turbo petrol engine uses direct injection, meaning the fuel system includes both a lower-pressure in-tank pump and a separate high-pressure pump mounted on the engine — these are two distinct parts with different symptoms when they fail. Diesel BlueHDi variants use an entirely different fuel system architecture.

Citroen C4 Fuel Pump: What It Does

The Citroen C4'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.

C4 I (2004–2010), 1.6/2.0 THP petrol, incl. VTS/VTR	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
C4 I/II (2004–present), 1.6 HDi diesel	Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump
C4 III (2020–present), 1.2 PureTech petrol	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
