A dual fuel system provides first and second fuels to internal an engine. Both fuels are stored in a storage tank, separated by a flexible membrane. A fuel rail receives either or both of the fuel types and distributes the fuels to fuel injectors. Upon shutdown of the engine, the second fuel is evacuated from the fuel rail into an auxiliary tank. The first fuel is subsequently supplied to the fuel rail from the storage tank. Upon a restarting of the engine after a predetermined time subsequent to the shutdown of the engine, the first fuel from the fuel rail is used for combustion. The second fuel from the auxiliary tank is then slowly bled into the engine or intake manifold. As the first fuel from the storage tank continues to supply the fuel rail, and the second fuel begins to supplement the first fuel in the fuel rail.
