A powerplant includes an engine (22) that may be disposed on a vehicle chassis 12 including a cab (14) or may be a stationary engine such as a generator set, and has a fuel delivery system (54) through which combustible fuel is introduced into the engine for combustion to power the engine. A tank (42) is disposed on the chassis below the cab at one side of the chassis. A bulkhead (70) divides the tank into a fuel supply reservoir (50) for holding a supply of fuel for the engine and a second supply reservoir (52), the latter reservoir holding a supply of fluid other than engine fuel. A first supply conduit (56) supplies fuel from the fuel supply reservoir to the engine fuel delivery system, and a second supply conduit (66) supplies fluid from the second supply reservoir to a portion of the powertrain. A return conduit (68) returns fluid from the powertrain to the is second supply reservoir and includes a walled passage (72) passing through the fuel supply reservoir. An exchangeable filter (62) is disposed external to the tank and may be placed in filtering relation to flow of fluid through the return conduit. Heat exchanger structure may be associated with the walled passage within the fuel supply reservoir. A thermostat valve (104) may be disposed in the return conduit to selectively divert returning fluid through other heat exchanger structure before the fluid enters the second reservoir.

[ What is claimed is:] [1.] An automotive vehicle comprising:a chassis comprising a powertrain,including a driven member for supporting the chassis on an underlying surface and an engine that has a fuel delivery system for introducing combustible fuel into one or more combustion chambers of the engine for combustion to power the engine and cause the driven member to propel the vehicle on the underlying surface;a walled tank that bounds an interior volume;a partition partitioning the interior volume of the tank into a fuel supply reservoir that is bounded in part by one portion of the tank wall and a second reservoir that is bounded in part by another portion of the tank wall;a supply conduit through which fuel is supplied from the fuel supply reservoir to the engine fuel delivery system; anda circuit for circulating a fluid other than engine fuel from the second reservoir to a portion of the powertrain and back to the second reservoir, the circuit comprising heat exchanger structure disposed within the fuel supply reservoir in heat exchange relationship with fuel in the fuel supply reservoir.
