The double wall tank design provides 110% fuel containment with a 990 gallon fuel tank mounted inside a protective secondary tank. The pumping system, fill ports and vents are also located within the secondary tank thereby securing the fuel supply behind two lockable, hatch-style doors. Used alone, the tank is a secure, on-site solution for storing and dispensing fuel. Used in conjunction with a trailer base also available from Thunder Creek, it becomes a mobile fueling station. Features like four fuel surge baffles, a rugged 8-in. C-channel chassis and torsion axles streamline transporting fuel between job sites.
