A cover (12) which has connectors (15) for a pressure gauge and a vacuum gauge is associable with the body. The body (2) has at least two outlets and a single inlet which are connected to a plurality of ducts for conveying the fuel oil. A user-activatable selection device (25) interacts with the ducts and is suitable to switch the direction of the circulation of the flow of the fuel oil as a function of the direction of rotation of the gears. <IMAGE>
