Cheap Peugeot 306 Fuel Injection Pump

The Peugeot 306 ran from 1993 to 2002, with a significant facelift in 1997 that updated the bodywork and some mechanical details, so year within that generation does still matter for this part. The most reliable guide is the engine code stamped on your block (also on your V5 or a VIN check), because pumps follow the engine, not the model year on the logbook. If you are sourcing a pump that crosses the pre-1997 and post-1997 facelift boundary, name that boundary to the breaker and ask them to confirm the part matches your specific engine code rather than assuming any 306 pump will do.

Engine code is the single most important detail for a diesel injection pump – it tells the breaker exactly which unit your engine was built around, in a way that year alone cannot. Two 306s of the same year could carry different diesel engines with pumps that are not interchangeable, so quoting only the year risks getting the wrong part. Find your engine code on the top or side of the block, or look it up via a VIN check, and give that to the breaker alongside your registration.

For the mechanical diesel injection pump, trim level does not affect fitment – the pump is determined by the engine code, not whether the car is an XR, XT, SR, or any other 306 grade. The GTI-6 is a petrol model with a different engine family entirely, so a pump from a diesel 306 would not cross over to it regardless of trim. Give the breaker your engine code and fuel type and they can match the correct pump without worrying about which badge is on the tailgate.

No, these are different engine families: the older 306 diesels used the XUD engine, while the HDi models introduced later in the production run use a common-rail system with a high-pressure pump that is not compatible with the older mechanical pump setup. Always give the breaker your exact engine code so they can supply the correct type, as mixing these up would leave the car unrunnable. Your V5 or a VIN check will confirm which engine code you have.

Whether a used diesel injection pump requires any ECU pairing, calibration, or immobiliser coding after fitting can vary and is not something that can be confirmed here as a blanket rule. You should raise this directly with the breaker and your fitting garage before buying, as the answer may depend on your specific engine code and vehicle age. It is worth having this conversation before purchase so there are no surprises on the labour side.

Petrol and diesel injection systems are entirely different in design and operating pressure, so a pump from a petrol 306 will not fit or function on a diesel engine and the same applies in reverse. When searching, make sure you specify your fuel type clearly alongside your engine code, as breakers stock both and a mix-up would mean a completely unusable part. Confirm fuel type and engine code with the breaker before any purchase.
