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.
