Mercedes W107, 350 SL, 1972

Mercedes W107, 350 SL, 1972, not starting.

It turned out to be a very simple problem. A lots of "rubbish" in the fuel pump, fuel filter and fuel line. After flushing the fuel pump and fuel line with some new petrol and changing the fuel filter, it was ok. In the process I found some information that might be useful for someone else.

Fuel pump and filter are located at the rear right hand side, close to the fuel tank.

Fusebox: Right hand side, behind the foot panel, beside the door.
