Peugeot 508 Fuel Injection Pump Replacement Parts

The Peugeot 508 first generation ran from 2011 to 2018, with a facelift arriving in 2014, so a 2013 and a 2016 car sit on opposite sides of that facelift boundary. Engine code is the deciding factor above all else, and if both cars share the same engine code the internal pump specification may well match, but ancillary fittings and mounting points can change across a facelift year so you should confirm the exact interchange against your registration with the breaker before buying.

The second-generation 508 arrived in 2018 as a completely new platform, so a pump from the first generation (2011–2018) should be treated as a different application entirely. Even if the engine code appears similar across generations, internal pump specifications and ancillary connections are likely to differ. Always supply your full registration or engine code to the breaker so they can verify compatibility before purchase.

Trim level does not affect fuel injection pump fitment on the 508; what matters is the engine code, fuel type, and gearbox type, not whether the car is badged Active, Allure, or GT. A pump pulled from an Allure will work in the same application as one from a GT provided the engine codes match, though you may notice cosmetic differences between donor and recipient cars such as interior or exterior trim that are irrelevant to the pump itself. Confirm the engine code from your V5 or a VIN check and supply it to the breaker.

The 2.0 HDi engine family covers several distinct engine codes that can have different pump specifications, so quoting '2.0 HDi' alone is not enough to guarantee fitment. The engine code — which you can find on your V5 certificate or via a VIN check — is the single most reliable detail to supply to the breaker. Gearbox type can also be a factor, so let the breaker know whether your car is manual or automatic when requesting a quote.

No — petrol and diesel fuel injection systems are fundamentally different in design and function, so the pump must match your fuel type exactly. Always confirm the fuel type alongside the engine code when contacting a breaker. Fitting the wrong type is not a case of simple incompatibility; it risks serious damage to the fuel system.

Whether a used injection pump requires coding or pairing to your vehicle's ECU or immobiliser system is something you must confirm directly with the breaker and ideally a Peugeot specialist before purchasing, as this can vary and is not something we can state as fact for your specific car. Some used pumps on later common-rail systems may need programming, which could add to the overall cost of the job. Make sure you factor this into your budget when getting quotes.
