A ventilation device for ventilating a motor vehicle tank. The ventilation device includes a filler pipe, a ventilation line, a degassing line, and a guide arc member. The ventilation line is to be fluidically connected at a first ventilation line end to the motor vehicle tank, and at a second ventilation line end to the filler pipe via a ventilation inlet. The degassing line is to be fluidically connected at a first degassing line end to the filler pipe via a degassing outlet. The guide arc member is arranged in the filler pipe to define a guide path for incoming vapor passing through the ventilation inlet into the filler pipe. The guide arc member is to facilitate flow of the incoming vapor between an inner wall of the filler pipe and the guide arc member along a periphery of the filler pipe along a periphery of the filler pipe such that a gaseous component of the incoming vapor escapes through the degassing outlet and a liquid component of the incoming vapor flows off through the filler pipe.
