Fuel for an engine is supplied from a first fuel tank. Return fuel from the engine is gathered in a second fuel tank for resupply to the engine. The second fuel tank is connected to and replenishable from the first fuel tank. The engine receives all its fuel from the second tank. On the second fuel tank there is a level device for regulating the fuel level. The level device is supplied with fuel from the first fuel tank via a first line. The first line has an inlet which is intended for fuel and which is connected to the second fuel tank in order to be able to remove fuel from the latter. The inlet is arranged at a level corresponding to the intended fuel level in the second fuel tank.
