OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Bosch 0 986 580 215 / Hüco 133594

Accuracy note: Covers the Citroen C4 Cactus (2014-2020) 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 133594 (complete petrol feed unit with sender, for cars with the internal fuel filter); Hella 8TF 358 305-331 (petrol feed unit with sender, 4-pin, gaskets included); Hella 8TF 358 146-231 (feed unit with sender, 4-pin, gasket included); Astemo 2503338 (diesel feed unit, 2.5 bar); Bosch 0 986 580 215 (electric in-tank feed unit); Delphi FG2701-12B1 (feed unit, supplied without gasket or pressure sensor); ERA 775443A (feed unit, 3 bar / 80 l/h, 4-pin); Ridex 1382F0022 (feed unit with sender and filter, 3.5 bar / 100 l/h, 4-pin)
Types & variants	Petrol PureTech cars take a pressurised feed unit with integral sender (Hüco 133594, Hella 305-331, 3-3.5 bar), while BlueHDi and HDi diesels take a low-pressure lift-pump module with sender (Astemo 2503338, Ridex 1382F0016). Two Hella/Ridex units (8TF 358 146-231, 1382F0023) are 2.5 bar modules with a 2-connector sender, which points to a different sender variant. All listings are complete modules; no bare in-tank pump is offered for this car, and only an Original Imperium rubber pre-supply pump appears.
Genuine (OE) numbers quoted	Kamoka 8400078 = 1525KG; Kamoka 8400046 = 15 25.N7; Kamoka 8400076 = 1400209180. No OE number is quoted against the Bosch, Hüco, Hella or Delphi parts.
Fitment notes	Check whether the car has the internal (lifetime) fuel filter before choosing a petrol unit, as Hüco specifies that fitment. Diesel modules are separate from petrol ones and run at far lower pressure. Every unit here is a complete module with sender, so the fuel gauge float is replaced at the same time; the pin count on the connector (2 or 4) should be matched to the old unit.

Worth Knowing: A Genuine Fuel Leak Fire Risk Confirmed on a Related Model — Citroen C4 Cactus Fuel Pump

Citroën confirmed a genuine safety recall on the C4 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. If your car shares the same fuel system generation, it's worth checking whether this or a related recall applies to your specific VIN, particularly if you're planning 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. One documented case saw an owner order a pump from an online used parts seller, only to receive the wrong manufacturer's unit for their specific engine, 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.

If you're chasing a genuine fuel pressure fault, 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.

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

This is one of the more inconveniently timed failures the Citroen C4 Cactus 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.

Citroen C4 Cactus Fuel Pump: What It Does

Delivering fuel from the tank to the engine at the correct pressure for combustion is the Citroen C4 Cactus'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.

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.

2014–2020, 1.6 HDi/BlueHDi diesel	Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump
2014–2020, 1.2 PureTech petrol	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
