Abstract: A tank for storing urea solution and a tank assembly for storing disparate fluids, such as diesel fluid and urea solution, are disclosed. The tank may further include a filler assembly and/or a sensor assembly, either of which are adapted to be connected to the tank without the use of separate fasteners, The tank assembly may include a reservoir and a sensor for automatically diverting non-conforming urea solution to the reservoir. A recess may be defined in the tank body in order to accommodate a strap for securing the tank to the frame of vehicle. The tank may include parallel sidewalls that include a projection on one and a corresponding indentation on the other in order to allow the tanks to be easily stacked during assembly.

Abstract: A fuel composition, preferably for use in internal combustion engines, comprising a water-in-oil emulsion of (a) a hydrocarbon fuel, such as gasoline, diesel fuel or fuel oil; (b) water; (c) preferably a water-soluble alcohol; and (d) a novel combination of surface-active agents to provide a clear composition which is stable against phase separation over a wide range of temperatures.
