ABSTRACT:
The invention proposes a fuel supply system for internal combustion engines, having a fuel tank (1) and a fuel reservoir (5) disposed therein, having a fuel pump (11), which drives one or more jet pumps (13), each by means of a supply line (21), the jet pumps (13) in turn filling the fuel reservoir (5) with fuel from the fuel tank (1). There is also a fuel line (7), which hydraulically connects the fuel reservoir (5) to the engine. During the starting of the engine, the fuel pump (11) feeds fuel into the fuel line (7), thus improving the starting behavior of the engine.
