Self air-bleeding fuel supply system for a diesel engine with gravity primed fuel feed pump

The present invention is directed to a fuel supply system, in particular for a diesel engine. It is an object of the present invention, to create a fuel supply system which is less susceptible to trouble in case after completely running dry of fuel. According to the present invention this objective is performed by a fuel supply system comprising a fuel tank (1), a fuel feed pump (3) for feeding fuel from said fuel tank, a fuel injection pump (8), injectors (10) taking fuel from said fuel injection pump, and a fuel filter (5) defining the filter degree of the fuel supplied to the injection pump, wherein said fuel feed pump (3) being arranged at a level below said fuel tank (1), and said fuel filter (5) ruling the filter degree of the fuel supplied to the injection pump (8) being arranged downstream said fuel feed pump (3).
