My roommate's 1965 W111 220S has the same problem. If it hasn't been run for a week or two, the fuel filter will be completely empty and it takes about 5 minutes of cranking (with pauses in between), nearly draining the battery before it will start.

The fuel tank is clean. The tank strainer is clean. All fuel lines are clear. The fuel hoses are new. The fuel pump is new and the carburetors are newer Webers.

I don't get it. Makes me love my diesels.
