Abstract
A fuel supply device for an internal combustion engine has a supply container, at least one feed pump for supplying a fuel from the supply container, a high pressure pump to which the fuel is supplied from the supply container by the feed pump, so that the fuel is supplied under high pressure at least indirectly to injection points of an internal combustion engine, the feed pump being driven mechanically by the internal combustion engine, and a further feed pump provided additionally to the mechanically driven feed pump and supplying the fuel from the supply container to the high pressure pump, the further feed pump having an electric drive and being operable independently from the mechanically driven feed pump.
