Our FUEL SAFE fuel tank/toolbox combos take fuel security to a whole new level! The fuel filler and fittings are inside a compartment under the lockable lid of the toolbox. The fill and fittings are in a compartment that is separated from the toolbox storage area. The toolbox has its own floor unlike others who offer an economy tank/toolbox combo that uses the top of the fuel tank as the toolbox floor.
