Cheap Mercedes-Benz X-Class Fuel Injection Pump

The X-Class ran as a single generation from 2017 to 2020 with no major facelift, so the engine codes used across that production run are your key reference point — if the engine code on your V5 matches the donor vehicle, fitment is far more likely to be straightforward. That said, whether ancillary mountings or fuel system components changed at any point mid-run is something you should confirm with the breaker against your specific registration before buying. Always supply your engine code when requesting a quote.

Yes — for mechanical fuel system parts like an injection pump, the engine code is the single most useful detail you can supply, sitting above year, trim, or any other factor. The X-Class used Nissan-sourced diesel engines, and the same engine code should point you to the correct pump regardless of what the badge says. Find your engine code on your V5 logbook or via a VIN check, and always quote it to the breaker.

Gearbox type can influence fuel system calibration and associated components, so it is worth telling the breaker which gearbox you have when requesting a quote. The injection pump itself is primarily tied to the engine code, but confirming gearbox type alongside the engine code gives the breaker the full picture they need. Never assume a pump from a manual car will drop straight into an automatic without checking first.

Trim level — whether Progressive, Power, or Styleline — does not affect which fuel injection pump is fitted; what matters is the engine code and fuel type. All X-Class trims share the same mechanical underpinnings for a given engine variant, so there is no pump specific to a higher or lower trim. Bear in mind you may receive a pump that looks cosmetically different in terms of brackets or sensors, so confirm ancillary details with the breaker against your registration.

Both years sit within the single 2017–2020 X-Class generation, so if the engine codes match you are in a good starting position. However, whether any mid-production changes were made to mounting points or ancillary components between a 2017 and 2019 build is something you should confirm with the breaker against your registration rather than assume. Quote your engine code and registration when asking for a quote to give the breaker the best chance of matching correctly.

Fuel type is a fundamental fitment factor — diesel and petrol injection pumps are entirely different components and are not interchangeable under any circumstances. The X-Class was primarily sold in the UK with diesel engines, but always confirm your fuel type alongside your engine code when contacting a breaker. Quoting your engine code removes any ambiguity and ensures the breaker can source the correct pump for your vehicle.
