Mercedes-Benz Vito Fuel Pump Replacement Parts

This is a critical generation boundary question: the W639 Vito ran from 2003 to 2014, while the W447 Vito launched in 2014, making these fundamentally different vehicles with different engines and fuel systems. Even if both are diesel, the engine codes will almost certainly differ across that boundary, and a W639 pump is very unlikely to be a straight swap onto a W447. Give your engine code (found on your V5 or a VIN check) to the breaker and ask them to confirm against the donor vehicle's code before buying.

Yes, all Vito variants have a fuel pump — both the diesel engines (which dominate UK examples) and the less common petrol and natural gas variants. On diesel Vitos the pump is typically a high-pressure injection pump or lift pump depending on the fuel system design, while petrol variants use an in-tank electric pump. Because the pump type and specification are tied directly to the engine, your engine code is the single most important detail to have ready when sourcing a used one from a breaker.

No, trim level has no bearing on fuel pump fitment — Sport, Tourer Select, Pro, and any other trim designation are cosmetic and equipment packages, not mechanical differences. What matters entirely is your engine code, fuel type, and in some cases gearbox type, all of which can vary independently of trim. Tell the breaker your engine code and they will match on that, ignoring whatever badge is on the back of the van.

Both are within the W639 generation (2003–2014), but the 109 CDI and 113 CDI designations indicate different engine outputs and potentially different engine codes, which can mean different fuel pump specifications. Check the exact engine code stamped on your engine or listed on your V5, then ask the breaker to confirm the donor vehicle carries the same code. Within the same engine code there is a reasonable chance of compatibility, but do not assume the 109 and 113 share identical pump hardware without that confirmation.

No — petrol and diesel fuel pumps are entirely different in design, pressure rating, and function, and are completely non-interchangeable. Diesel systems operate at far higher pressures and the pump internals are not compatible with petrol. Always source a pump that matches your fuel type and engine code exactly, and make sure the breaker knows both when they are pulling the part.

This is something you should raise directly with the breaker and ideally with a Mercedes-specialist independent garage, as ECU pairing and immobiliser coding requirements can vary by engine type and model year and are not something that can be stated as a blanket rule here. Some Vito fuel systems do involve electronic communication between the pump and engine management, which may require coding after fitting. Make sure whoever is fitting the pump is aware it is a used part from a different vehicle and can advise on any programming steps needed.
