About this part
The fuel pump on your 300b W186 feeds fuel from the tank to the engine at the pressure the injection or carburetor needs. Long cranking before it fires, a loss of power under load or stalling when warm are the typical signs that it is failing.
Frequently asked questions
What should I check when buying a fuel pump for the Mercedes-Benz 300b?
Match the part number on the old pump and the engine code of your 300b W186: petrol and diesel versions, and often different years, use different pumps and pressures. Ask exactly what is included, because the same name is used for a bare pump insert and for a complete unit.
New, used or rebuilt?
A used pump is the cheapest, but its wear does not show from the outside: ask whether it was tested. Affordable new aftermarket pumps exist for many models. For expensive high-pressure and injection pumps, a rebuilt unit with a warranty is often the best compromise.
