In order to be able to refuel an engine in a safe and simple manner, for example an outboard engine in the open sea, one can with advantage use a connection hose (4) between the tank (1) and the reserve fuel container (10). The hose (4) consists of a twin hose comprising an air channel (6) and a liquid channel (5) with the same sectional area. The air channel is extended so that it projects up over the liquid channel (5) in the filling position. The ends of the hose are provided with elastic plugs (3, 7) which have ribs (8) on their outer sides. This ensures a tight connection between the hose and the spout. When the hose with the plug is secured, the container (10) is raised and the liquid will flow in until it reaches up to the channel (6) and shuts off the evacuation of air from the tank (1). Overflow is thus prevented, and the risk of fire and/or the danger of explosion is hereby eliminated. |
