An electrical connector including a plurality of electrical contacts; and a housing. The housing includes a pre-mold housing member which has been overmolded onto the electrical contacts; and an overmold housing member which has been overmolded onto the electrical contacts and the pre-mold housing member. The pre-mold housing member comprises an exterior sealing surface which is not covered by the overmold housing member. The exterior sealing surface of the pre-mold housing member loops around an exterior lateral side of the housing which is between front and rear ends of the housing.

What is claimed is: 1. An electrical connector comprising: a plurality of electrical contacts; and a housing having the electrical contacts connected thereto, wherein the housing comprises: a pre-mold housing member which has been overmolded onto the electrical contacts; and an overmold housing member which has been overmolded onto the electrical contacts and the pre-mold housing member, wherein the overmold housing member at least partially forms a front end and a rear end of the housing, wherein the pre-mold housing member comprises an exterior sealing surface which is not covered by the overmold housing member, and wherein the exterior sealing surface of the pre-mold housing member loops around an exterior lateral side of the housing which is between the front and rear ends. 2. An electrical connector as in claim 1 wherein the electrical contacts each comprise a first end, an opposite second end and a bent section between the first and second ends, wherein the first end comprises a female connection area, and wherein the overmold housing member is overmolded onto the bent sections. 3. An electrical connector as in claim 2 wherein the pre-mold housing member is overmolded onto the female connection areas as separate tubes. 4. An electrical connector as in claim 3 wherein the overmold housing member comprises a tube section which is spaced from and surrounds the separate tubes. 5. An electrical connector as in claim 1 wherein the pre-mold housing member comprises a first end on the electrical contacts, an opposite second end covered by the overmold housing member, and a middle section which forms the exterior sealing surface. 6. An electrical connector as in claim 5 wherein the middle section comprises an outwardly projecting annular flange. 7. An electrical connector as in claim 6 wherein the overmold housing member forms an outward extending ledge facing the exterior sealing surface such that the exterior sealing surface is located in a recess between the ledge and the flange. 8. An electrical connector as in claim 1 wherein the overmold housing member comprises a middle section entirely contained within the pre-mold housing member between the front and rear ends of the housing. 9. An electrical connector as in claim 8 wherein the pre-mold housing member comprises interior holes which are only open to front and rear ends of the pre-mold housing member, and wherein the middle section of the overmold housing member is located in the holes. 10. An electrical connector as in claim 1 wherein pre-mold housing member has been insert molded onto the electrical contacts such that the exterior sealing surface of the pre-mold housing member comprises an entirely smooth surface without mold parting lines. 11. A fuel pump assembly comprising: a fuel pump; an electrical connector as in claim 1 connected to the fuel pump; a can member connected to the fuel pump and having a front end of the electrical connector extending through the can member into connection with the fuel pump; and an O-ring seal directly compressed between the exterior sealing surface of the pre-mold housing member and the can member. 12. A fuel pump assembly as in claim 11 wherein the can member comprises an end with a flange adapted to mate with a flange of the exterior sealing surface of the pre-mold housing member. 13. A fuel system electrical connector comprising: a plurality of electrical contacts each having a first end, an opposite second end and a bent section between the first and second ends, wherein the first end comprises a female connection area; and a housing connected to the electrical contacts, wherein the housing comprises: a pre-mold housing member which has been overmolded onto the electrical contacts, wherein portions of the pre-mold housing member form separate tubes surrounding each of the female connection areas; and an overmold housing member which has been overmolded onto the bent sections of the electrical contacts and onto the pre-mold housing member, wherein the overmold housing member at least partially forms a front end and a rear end of the housing, wherein the pre-mold housing member comprises an exterior sealing surface which is not covered by the overmold housing member, wherein the exterior sealing surface of the pre-mold housing member loops around an outer lateral side of the housing located between front and rear outer lateral sides of the housing formed by the overmold housing member, and wherein areas of contact between the overmold housing member, the electrical contacts and the pre-mold housing member form tortuous paths between the front and rear ends of the housing to prevent flow of fuel vapor along the paths through the connector between the front and rear ends of the housing. 14. A fuel system electrical connector as in claim 13 wherein the overmold housing member comprises a tube section which is spaced from and surrounds the separate tubes of the pre-mold housing member. 15. A fuel system electrical connector as in claim 13 wherein the pre-mold housing member comprises a first end on the electrical contacts, an opposite second end covered by the overmold housing member, and a middle section which forms the exterior sealing surface. 16. A fuel system electrical connector as in claim 15 wherein the middle section comprises an outwardly projecting annular flange. 17. A fuel system electrical connector as in claim 16 wherein the overmold housing member forms an outward extending ledge facing the exterior sealing surface such that the exterior sealing surface is located in a recess between the ledge and the flange. 18. A fuel system electrical connector as in claim 13 wherein the overmold housing member comprises a middle section entirely contained within the pre-mold housing member between the front and rear ends of the housing. 19. A fuel system electrical connector as in claim 18 wherein the pre-mold housing member comprises interior holes which are only open to front and rear ends of the pre-mold housing member, and wherein the middle section of the overmold housing member is located in the holes. 20. A fuel system electrical connector as in claim 13 wherein pre-mold housing member has been insert molded onto the electrical contacts such that the exterior sealing surface of the pre-mold housing member comprises an entirely smooth surface without mold parting lines. 21. A fuel pump assembly comprising: a fuel pump; a fuel system electrical connector as in claim 13 connected to the fuel pump; a can member connected to the fuel pump and having a front end of the electrical connector extending through the can member into connection with the fuel pump; and an O-ring seal directly compressed between the exterior sealing surface of the pre-mold housing member and the can member. 22. A fuel pump assembly as in claim 21 wherein the can member comprises an end with a flange adapted to mate with a flange of the exterior sealing surface of the pre-mold housing member. 23. A method of manufacturing an electrical connector comprising: overmolding a first housing member onto the electrical contacts; overmolding a second housing member onto the electrical contacts and the first housing member, wherein the first housing member comprises an exterior sealing surface which is not covered by the second housing member, and wherein the exterior sealing surface of the first housing member loops around an exterior lateral side of the second housing member between front and rear exterior lateral sides of the second housing member.
