A fuel pump module assembly includes a fuel pump 10 having an inlet 16 and an outlet 17. The fuel pump 10 is constructed and arranged to send fuel from the outlet to an engine of a vehicle. The fuel pump has a vapor purge port 13 therein constructed and arranged to permit fuel vapor to exit the fuel
A fuel pump module assembly includes a fuel pump 10 having an inlet 16 and an outlet 17. The fuel pump 10 is constructed and arranged to send fuel from the outlet to an engine of a vehicle. The fuel pump has a vapor purge port 13 therein constructed and arranged to permit fuel vapor to exit the fuel pump generally downwardly. A pump filter 14 is disposed below the vapor purge port 13 and is associated with the inlet 16 of the fuel pump. The pump filter is constructed and arranged to filter fuel prior to entering the inlet. A vapor deflector 18 is associated with the vapor purge port 13 and is constructed and arranged to deflect vapor, which exits the vapor purge port, so as to continue to move generally downwardly but away from the pump filter.

What is claimed is: 1. A fuel pump module assembly comprising: a fuel pump having an inlet and an outlet, the fuel pump being constructed and arranged to send fuel from the outlet to an engine of a vehicle, the fuel pump having a vapor purge port therein constructed and arranged to permit fuel vapor to exit the fuel pump generally downwardly, a pump filter disposed below the vapor purge port and being associated with the inlet of the fuel pump, the pump filter being constructed and arranged to filter fuel prior to entering the inlet, and a vapor deflector, between the vapor purge port and the pump filter, constructed and arranged to deflect vapor, which exits the vapor purge port, so as to continue to move generally downwardly but away from the pump filter. 2. The assembly of claim 1, further comprising a secondary filter associated with the fuel pump, and a pump retaining structure supporting the fuel pump with respect to the secondary filter. 3. The assembly of claim 2, wherein the vapor deflector is part of the pump retaining structure. 4. The assembly of claim 2, wherein the pump retaining structure supports the fuel pump in a suspended manner with respect to the secondary filter. 5. The assembly of claim 2, wherein pump retaining structure is composed of plastic material. 6. The assembly of claim 4, wherein the pump retaining structure comprises: a base member coupled to the secondary filter, and a pump retainer member coupled to the base member so as to be in spaced relation with respect to the base member, the pump retainer member supporting the fuel pump. 7. A fuel pump module assembly comprising: a fuel pump having an inlet and an outlet, the fuel pump being constructed and arranged to send fuel from the outlet to an engine of a vehicle, the fuel pump having a vapor purge port therein constructed and arranged to permit fuel vapor to exit the fuel pump generally downwardly, a pump filter disposed below the vapor purge port and being associated with the inlet of the fuel pump, the pump filter being constructed and arranged to filter fuel prior to entering the inlet, and means for deflecting vapor which exits the vapor purge port so as to continue to move generally downwardly but away from the pump filter, the means for deflecting vapor being disposed between the vapor purge port and the pump filter. 8. The assembly of claim 7, further comprising a secondary filter associated with the fuel pump, and a pump retaining structure supporting the fuel pump with respect to the secondary filter. 9. The assembly of claim 8, wherein the means for deflecting is a deflector that is part of the pump retaining structure. 10. The assembly of claim 8, wherein the pump retaining structure supports the fuel pump in a suspended manner with respect to the secondary filter. 11. The assembly of claim 8, wherein pump retaining structure is composed of plastic material. 12. The assembly of claim 10, wherein the pump retaining structure comprises: a base member coupled to the secondary filter, a pump retainer member coupled to the base member so as to be in spaced relation with respect to the base member, the pump retainer member supporting the fuel pump. 13. The assembly of claim 12, wherein the deflector is coupled to the pump retainer member. 14. A pump retaining structure for supporting a fuel pump with respect to a secondary fuel filter and for deflecting vapor away from an initial filter, the pump retaining structure comprising: a base member constructed and arranged to be coupled to the secondary filter, a pump retainer member coupled to the base member so as to be in spaced relation with respect to the base member, the pump retainer member being constructed and arranged to retain and support the pump in a suspended manner with respect to the secondary filter, and a vapor deflector constructed and arranged to deflect vapor, exiting a vapor purge port of the fuel pump, away from the initial filter. 15. The structure of claim 14, wherein the base member, the pump retainer member and the vapor deflector are formed integrally from plastic. 16. The structure of claim 14, wherein the deflector is coupled to the pump retainer member. 17. The assembly of claim 5, wherein the vapor deflector is coupled to the pump retainer member.
