Abstract

A device for an arrangement inside a fuel tank, provided with pumps and filters for supplying and filtering fuel that is fed to an internal combustion engine, whereby the fuel is conveyed from the bottom area of the tank through a first filter into a collector chamber and fuel is conveyed from said collector chamber by means of a second pump through a second filter to the internal combustion chamber. Both pumps are arranged in a pump unit. The collector chamber is arranged vertically above the pump unit and the filter with respect to the fitting position of the device and is embodied as an open overflow container, whereby the inventive device can be produced in a rational manner and offers good functionality.
