Seat Ibiza Fuel Pump: Specs, Fitment & Common Faults
On the Ibiza, the fuel pump primes when the driver's door opens, not just the ignition — a genuinely distinct diagnostic clue, plus why running low on fuel can damage the pump itself.

OEM Part Number: 6C0919050B (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Bosch 0 986 580 832 / Pierburg 7.07795.41.0
| Fuel pumps / feed units (aftermarket) | Bosch 0 986 580 832 (in-tank feed unit); Hella 8TF 358 106-431 (feed unit with sender, 5-pin, no pressure regulator in the unit); Pierburg 7.07795.41.0 (feed unit, 0.5 bar, 12 V / 5.7 A, 2 connectors, 108.75 mm flange, 229 mm long); Delphi FG2423-12B1 (feed unit, no pressure sensor); Delphi FG2498-12B1 (feed unit, no pressure sensor); ERA 775712A (feed unit, 0.5 bar / 120 l/h, 5-pin, 12 V); Ridex 1382F0017 (feed unit with sender, petrol, 4 bar, 13.5 V / 9.4 A); Ridex 1382F0359 (feed unit with sender, petrol, 4 bar) |
|---|---|
| Types & variants | The split is by pressure: the petrol units run at 4 bar with sender (Ridex 1382F0017 and 1382F0359, Hoffer 7507341) while the diesel units are low-pressure lift modules at 0.5 bar (Pierburg 7.07795.41.0, ERA 775712A). The Hella 8TF 358 106-431 is a 5-pin module with sender sold without a pressure regulator, which means the regulator is retained from the old unit. The two Delphi feed units differ in length (266 mm versus 256 mm). Energy G10092 and ESEN SKV 02SKV277 are bare MPI in-tank cartridges with filter for fitting into the existing housing. |
| Genuine (OE) numbers quoted | 6C0919050B (Hoffer 7507341) |
| Fitment notes | The petrol 4 bar module and the diesel 0.5 bar module share the same 108 mm flange but are not interchangeable; the 1.2 TDI and 1.6 TDI need the lift unit only. A bare pump can be fitted into the old housing on petrol cars, but the Hella unit without regulator needs the original regulator transferred over. The 6C0919050B OE number also covers the VW Polo 6R and Skoda Fabia II. |
A Genuinely Useful Diagnostic Clue: The Door-Opening Prime — Seat Ibiza Fuel Pump
A genuinely useful, specific diagnostic detail worth knowing: on this shared VW Group platform, the in-tank fuel pump is designed to prime briefly the moment the driver's door is opened, not only when the ignition is turned to "on" — you can often hear a faint whine from the rear of the car for a couple of seconds right after opening the door. If you don't hear this at all, it's worth checking the door control module and door sensor before assuming the fuel pump itself has failed — a known failure point on related VW Group models is exactly this module failing to detect the door opening, which also tends to show up as the interior light not coming on and the door-open buzzer not working, giving you a useful way to confirm whether this is genuinely the cause.
Seat Ibiza Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Seat Ibiza, this particular failure has a knack for terrible timing, stranding drivers mid-journey instead of giving fair warning while the car's parked up safely. Spotting the early signs early enough is what stands between a routine fix and a roadside breakdown.

Seat Ibiza Fuel Pump: What It Does
Getting fuel from tank to engine at the correct combustion pressure is down to the fuel pump, and on the Seat Ibiza that pump sits inside the tank, submerged in fuel. That location is exactly why swapping out such a small part is rarely a quick job.
Seat Ibiza Fuel Pump: Generations & Engines: Fuel Pump Type
| Mk2/6K (1993–2002), all petrol & 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 |
|---|---|
| Mk3/6L (2002–2008), 1.4/1.9 TDI diesel | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| Mk3/6L FR/Cupra (2004–2008), 1.8T & 1.9 TDI (130-160PS) | 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 |
| Mk4/6J (2008–2017), 1.2/1.4 TSI petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Mk4 Cupra (2009–2015), 1.4 TSI twincharger | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Mk5 (2017–present), 1.0 TSI petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
