摘要

The module (10) has a casing (14) defining a pumping compartment (16) in which a pump is filled with fuel. A control unit (28) of the pump is arranged into a control housing (26). An electrical connection (30) is provided between the pumping compartment and the control housing, and passes through a ventilation chamber (38) such that the fuel is succeeded from the pumping compartment by infiltrating along the electric connection and enters the ventilation chamber and leaves without infiltrating upstream for ensuring perfect sealing of the control housing.
