Vauxhall Astra Fuel Pump: Specs, Fitment & Common Faults
Diesel Astras genuinely use two separate fuel pumps working together — plus a specific, well-documented electronics fault on older diesel models that's often cheaper to repair than replace.

| Fuel pumps / feed units (aftermarket) | Bosch 0 580 314 097 (bare in-tank pump, with mounting material and connector parts); Delphi FE0438-12B1 (bare in-tank pump, petrol, metal, 128 mm, without pressure sensor); Delphi FE0429-12B1 (bare in-tank pump, petrol, metal, 113 mm); Delphi FE0448-12B1 (in-tank pump, petrol, metal, 179 mm); Pierburg 7.21440.51.0 (low-pressure pump, 0.3 to 0.4 bar, 2-pin, 2 A); ERA 770048A (bare in-tank pump, 3 bar / 90 l/h, 2-pin); Ridex 458F0081 (bare in-tank pump, 3 bar / 90 l/h, 2-pin, 208 mm); Laser Tools 7998 (pump tool, OE EN-50885, not a pump). |
|---|---|
| Types & variants | All listings are bare electric pumps or pump modules; no complete feed unit with a level sender is offered for the Astra K. The 1.0, 1.2 and 1.4 turbo petrols use an in-tank pump of around 3 to 4 bar |
| Genuine (OE) numbers quoted | Laser Tools 7998 quotes EN-50885; Meat & Doria 76416 and Hoffer 7506416 quote 170429F500; Kamoka 8410005 quotes 8450008680; Meat & Doria 76041 quotes 8941674933 (carburettor pump, not relevant). |
| Fitment notes | Petrol in-tank pumps on the Astra K can be swapped into the original housing while the sender and float stay in place, which keeps the fuel gauge calibration; the tank is accessed under the rear seat. Diesel owners need the complete sender module, which is not listed here. |
Diesel Astras Genuinely Use Two Separate Pumps — Worth Understanding Before Diagnosing a Fault — Vauxhall Astra Fuel Pump
If your Astra is diesel-engined, it's worth knowing there are genuinely two separate fuel pumps working together, not one: a low-pressure "lift" pump inside the tank, and a high-pressure pump mounted on the engine and driven by the timing belt or camshaft. A fault can originate in either one, and correctly identifying which is at fault matters — a whining noise when the ignition is turned to "on" (before starting) confirms the in-tank lift pump is at least attempting to prime the system; silence here points to the lift pump, its fuse, or its relay as the likely cause, while a car that primes normally but still struggles to start or runs rough under load points more toward the engine-mounted high-pressure pump instead.
Vauxhall Astra Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Vauxhall Astra, there's rarely a convenient time for this to fail — it tends to strike mid-journey rather than while the car's sitting safely on the drive. Knowing what the early symptoms look like buys valuable time to get ahead of it.

Vauxhall Astra Fuel Pump: What It Does
The job here is simple in principle — draw fuel from the tank, deliver it to the engine at the right pressure — but the Vauxhall Astra's fuel pump sits submerged inside the tank, which makes physical access for replacement far more involved than the small part itself implies.
Vauxhall Astra Fuel Pump: Generations & Engines: Fuel Pump Type
| Astra H (2004–2009), 1.6/1.8 petrol | 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 |
|---|---|
| Astra H (2004–2009), 1.7/1.9 CDTi diesel | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| Astra H VXR (2005–2010), 2.0 turbo (Z20LEH) | 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 |
| Astra J (2009–2015), 1.4 Turbo & 1.6 SIDI Turbo | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Astra J (2009–2015), 1.6 CDTi "whisper diesel" | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| Astra J VXR/GTC VXR (2012–2018), 2.0 turbo (B20NFT) | 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 |
| Astra K (2015–2019), 1.4 Turbo & 1.6 CDTi | 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 |
| Astra K facelift (2019–2021), 1.2 turbo | 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 |
| Astra K GSi (2018–2021), 2.0 turbo (A20NHT) | 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 |
| Astra L (2021–present), 1.2 PureTech petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
