An auxiliary fuel-feed device to be installed in the fuel-feed circuit of internal-combustion engine equipped with return tubing (19) for excess feed fuel, which provides a means (21) that allows an additional amount of fuel to be added to the return-fuel flow that is sufficient to ensure that, per unit time, the sum of the volume of return fuel and the volume of additional fuel, deposited in the tank (10) pertaining to the fuel-feed auxiliary device, will be greater than the volume of the fuel removed from the auxiliary tank (10) by the feed tubing (16), thus being ensured that, while the internal-combustion engine is running, the tank pertaining to the fuel-feed auxiliary device is continuously supplied and its maximum level maintained, with no need to resort to auxiliary pumping measures for such purposes. |
