About this part
The fuel pump on your 503 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 BMW 503?
Match the part number on the old pump and the engine code of your 503: 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.
