A fuel delivery pump for a fuel injection pump for internal combustion engines, including a pair of gears that mesh with each other and are driven to rotate in a pump chamber. The pair of gears deliver fuel from an intake chamber connected to a storage tank, along a supply conduit that is formed between the end face of the gears and the circumference wall of the pump chamber, into a pressure chamber connected to the fuel injection pump. A conduit is provided that connects the intake chamber to the pressure chamber. The conduit can be connected to a ventilation device, and that upstream and downstream of the ventilation device, a pressure valve is provided for a directed fuel flow in the conduit.
