ABSTRACT OF THE INVENTION The tank fill locking system includes a special coupling adapted to fit upon the top of the tank fill pipe within the manhole. A flat top cap is removably attached to the coupling and includes aligned lock receiving openings when the handle is moved to the closed position. An upper, first, hardened steel plate overfits the fill cap within the manhole and is provided with suitable brackets to engage both the handle and the locks. Preferably, straight shackle locks are employed. A second or inner locking plate secures within the coupling below the flat cap and is also provided with a lock to lock the second plate within the coupling and thereby prevent access to the tank through the fill pipe.
