A fuel supply system for an auxiliary vehicle heating device to which fuel can be supplied via the fuel supply system of an internal combustion engine. A fuel storage reservoir is provided which supplies fuel to an auxiliary vehicle device, and is arranged in the engine compartment of the vehicle. The storage reservoir is filled with fuel in a batchwise manner from any vehicle-contained fuel supply source, preferably via an elongated slot opening into a fuel receiving space of the reservoir from a fuel line that is in bypassing relationship to the reservoir. The fuel storage reservoir has a ventilating value leading to the atmosphere. In accordance with one aspect of the inventive concept, the fuel storage reservoir can receive a fuel pump which forwards the fuel from the fuel storage reservoir to the auxiliary heating device, so that the pump and reservoir form a single-part unit. If desired, draining devices and/or heating units can be provided in the fuel storage reservoir in order to ensure a reliable operation of the auxiliary heating device, even at low temperatures.
