Skoda Octavia Fuel Pump: Specs, Fitment & Common Faults
On the Octavia, hesitancy specifically when the fuel level drops below a quarter tank is a genuine, documented clue pointing to the in-tank pump — plus an honest warning about diagnosis costs.

OEM Part Number: 5Q0919050AP (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Bosch 0 580 200 392 / Hüco 133572
| Fuel pumps / feed units (aftermarket) | Hüco 133572 (complete feed unit with sender, petrol); Astemo 2503377 (feed unit, petrol, 4.4 bar); Astemo 133134 (feed unit, diesel); Astemo 2503134 (feed unit, diesel); Astemo 2503292 (feed unit, diesel); Hella 8TF 358 304-911 (feed unit with sender, diesel, two plugs 4-pin and 3-pin); Bosch 0 580 200 392 (in-tank feed unit with level sensor in main tank, connector parts included); Delphi FG2690-12B1 (feed unit, no pressure sensor) |
|---|---|
| Types & variants | The Octavia III shares the Leon 5F fuel system. Petrol is covered by the 4-4.4 bar single-plug modules (Hüco 133572 with sender, Astemo 2503377, ERA 775299A, Meat & Doria 77017, Kamoka 8400067) and the 5 bar / 190 l/h 7-pin unit (ERA 775547A) for the vRS 2.0 TSI. Diesel is covered by the Astemo 134 and 292 feed units and the two-plug swirl-pot modules with sender from Hella and Ridex. Metzger 2250381 is a 5 bar in-tank assembly. No bare pump or pre-supply pump is listed. |
| Genuine (OE) numbers quoted | 1K0919051BE (Meat & Doria 77017); 5Q0919050AP (Meat & Doria 77729); ERA 775299A lists repair kit 775299 |
| Fitment notes | The 1K0919051BE number is the carry-over Golf V/VI petrol module and the 5Q0919050AP is the later MQB module, so the OE number on the old unit decides which family is needed. Petrol and diesel modules cannot be swapped; the 1.6 and 2.0 TDI take the two-plug diesel module with the sender built in. The module is replaced complete on this generation. |
A Genuine Diagnostic Clue: Does It Happen Only With a Low Tank? — Skoda Octavia Fuel Pump
A genuinely useful diagnostic clue reported consistently by owners: hesitancy or a longer crank specifically when the fuel level drops below around a quarter tank, that clears up once refuelled, points toward a struggling in-tank low-pressure pump rather than a completely failed unit — the pump can still work adequately with a fuller tank but struggles to pick up fuel efficiently as the level gets low, particularly if there's any sediment or debris settled at the bottom of the tank. This pattern is worth mentioning specifically to whoever is diagnosing the car, since it points toward the in-tank pump rather than the separate, more expensive high-pressure pump mounted on the engine.
Skoda Octavia Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Skoda Octavia, few faults pick a worse moment to happen than this one, which has a habit of leaving drivers stranded mid-journey rather than failing safely at home. Catching the early signs gives you a genuine head start before that happens to you.

Skoda Octavia Fuel Pump: What It Does
On the Skoda Octavia, fuel reaches the engine at the pressure combustion needs thanks to the fuel pump, which draws it straight from the tank. It sits submerged inside the tank itself, and that positioning is a big part of why replacement takes more effort than the part's size would suggest.
Skoda Octavia Fuel Pump: Generations & Engines: Fuel Pump Type
| Mk1 (1996–2010), 1.6/1.9 TDI diesel | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
|---|---|
| Mk1 vRS (2001–2006), 1.8T petrol (EA113) | 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 |
| Mk2 (2004–2013), most 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 |
| Mk2 vRS (2005–2013), 2.0 TFSI/TSI petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Mk3/Mk4 (2013–present), 1.5 TSI petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Mk3/Mk4 vRS (2013–present), 2.0 TSI petrol (180-245PS depending on year) | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Mk3/Mk4, 2.0 TDI diesel | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
