Second Hand Peugeot 508 Fuel Pump

The Peugeot 508 first generation ran from 2010 to 2018, with a facelift arriving in 2014, so a 2013 and a 2015 car sit either side of that boundary. Fitment of the fuel pump depends primarily on your engine code rather than the model year, but because ancillary and mounting details can change around a facelift, crossing that 2014 boundary means you should confirm compatibility with the breaker against your exact registration before buying.

No — diesel and petrol engines use entirely different fuel systems, and the fuel pumps are not interchangeable between the two fuel types. The diesel 508 uses a high-pressure injection pump suited to compression ignition, while the petrol 508 uses a lower-pressure pump matched to its fuel system; you must match fuel type exactly. Always tell the breaker whether your car is petrol or diesel as a minimum, alongside your engine code.

Trim level — whether Active, Allure, or GT — has no bearing on fuel pump fitment; what matters is the engine code, fuel type, and gearbox type. A GT and an Active sharing the same engine code and fuel type will use the same pump. Focus your search on the engine code, which you can find on your V5C or through a VIN check, rather than on trim designation.

Yes, all Peugeot 508 variants — both petrol and diesel — have a fuel pump, as the car is a conventionally fuelled internal combustion engine model with no pure-electric or fuel-cell variant in this generation. Petrols typically have an in-tank low-pressure pump, while diesels additionally rely on a high-pressure pump driven by the engine, so make sure you and the breaker are clear on which pump you actually need. If your car has developed a fuel delivery fault, a diagnostic check is worth doing first to confirm whether it is the in-tank pump, the high-pressure pump, or another component at fault.

The single most useful piece of information is your engine code, which you can find on your V5C logbook or via a VIN decoder — it is more reliable than year or trim alone because PSA engines were shared across multiple models and years. Alongside the engine code, tell the breaker your fuel type (petrol or diesel), your gearbox type (manual or automatic), and your registration plate so they can cross-reference everything. Whether your car is a saloon or SW estate does not affect pump fitment, so you do not need to worry about body style.

The second-generation Peugeot 508 launched in 2018 on a new EMP2 platform and uses different engines to many first-generation cars, so in almost all cases the fuel pumps will not be interchangeable between the two generations. Some engine codes may appear across both generations, but mounting arrangements and system pressures can differ, so always confirm compatibility with the breaker using your specific engine code and registration rather than assuming cross-generation fitment.
