Abstract

PURPOSE:To perform smooth fuel feeding to the respective underground tanks, by providing a fuel feeding apparatus composed of an manifold connected to a tank lorry or the like, a plurality of fuel feeding pipes each communicated with the under ground storage tank and operating valves mounted on the respective fuel feeding pipes, and controlling the fuel feeding valves on the basis of the level of the remaining fuel in the tank. CONSTITUTION:A fuel feeding apparatus 2 comprises a manifold 3 connected to a tank lorry R or the like, a plurality of fuel feeding pipes 4 each connected to the manifold 3 at one end and communicated with an underground storage tank 1 at the other end, and operating valves mounted on the respective fuel feeding pipes and controlling the amount of fuel fed to the tank 1. Accordingly, when a supply pipe R-1 is connected to a fuel filling port 7 of the fuel feeding apparatus 2, fuel is simultaneously fed from the manifold through the operating valves to the respective underground storage tanks 1. Each storage tank is provided with a level gauge which detects the level of a remaining fuel therein. On the basis of the detected fuel level, a controlling unit S controls opening and closing of the operating valve 5 whereby fuel feeding to the underground storage tanks 1 terminates when a desired fuel level in the tanks is reached.
