Abstract: A reservoir structure of a fuel suction unit or pump module for a diesel vehicle is provided. The reservoir structure includes a reservoir 10 having a bottom surface 14. A primary opening 12 is provided in the bottom surface for permitting fuel to pass from a fuel tank of the vehicle into the reservoir. A secondary opening 16 is provided in the reservoir 10 that is elevated from the bottom surface 14. A valve member 18 is associated with the secondary opening 16. The valve member 18 is constructed and arranged to close the secondary opening under certain pressure conditions in the reservoir and, under pressure conditions in the reservoir different from the certain pressure conditions, to permit fuel to enter the reservoir through the secondary opening in the event the primary opening is substantially blocked.
