The RDS Fuel Transfer Tank/Toolbox Combo is designed for transferring diesel fuel, gasoline or aviation fuel from the bed of a pickup to automobiles, heavy equipment, boats, 4-wheelers, generators, or anything else requiring fuel that you may have. Enjoy the convenience of a gas station that goes where you go. A toolbox is also built in for extra storage. DOT approved aluminum fuel tanks do not rust, which protects fuel from contamination. This tank can also be used as a diesel auxiliary tank when used in conjunction with the optional Diesel Install Kit (sold separately). It is the user’s responsibility to comply with local, state and federal requirements pertaining to safe transportation, loading and discharging tank contents.
