Mercedes-Benz MB100 Fuel Pump Replacement Parts

Yes, the MB100 van (produced approximately 1988 to 1996) was available with petrol and diesel engine variants, and all of them require a fuel pump to deliver fuel from the tank to the engine. Petrol versions use a mechanical or electric fuel pump depending on the specific engine, while diesel variants use a mechanical fuel lift pump feeding the injection system. So a fuel pump does genuinely exist on this model, though the exact type varies by engine.

The MB100 had a relatively long and largely consistent production run from around 1988 to 1996, but there were detail changes across those years that may affect whether a pump from one vehicle swaps directly onto another. Engine code is the single most important thing to match here — check your V5 or run a VIN check to confirm your engine code before ordering. Whether ancillary mountings or fuel system connections changed at any specific point in production is best confirmed with the breaker against your registration, as mid-run changes are not always well-documented on this model.

Yes, absolutely — fuel type is critical for this part and petrol and diesel fuel pumps are completely different components that are not interchangeable. Diesel versions use a mechanical lift pump to supply the injection pump, whereas petrol versions use either a mechanical or electric pump depending on the engine fitted. Always specify your fuel type and engine code to the breaker to make sure you receive the correct unit.

Gearbox type can have an indirect effect on engine specification and fuelling setup, so it is worth mentioning to the breaker when you request a quote. The fuel pump itself is primarily matched by engine code and fuel type rather than gearbox, but confirming the full drivetrain spec helps the breaker cross-reference the correct part from their dismantled vehicle. Lead with your engine code and fuel type, then add gearbox details as supporting information.

No, body style and load configuration do not affect fuel pump fitment on the MB100. The fuel pump is a mechanical part that follows the engine, not the body, so a panel van and a window van with the same engine code will use the same pump. Focus entirely on matching engine code and fuel type rather than worrying about the body variant when sourcing this part from a breaker.

The most important detail you can supply is your engine code, which you can find on your V5 logbook or via a VIN check — this tells the breaker exactly which engine variant your van has, which is far more reliable than going by year alone. Also confirm your fuel type (petrol or diesel) clearly, as the pumps are completely different. If your van has any known modifications to the fuel system, mention those too, and always ask the breaker to confirm the part against your registration before committing.
