A method provides wiring associated with a flange of a fuel delivery module for use in a fuel tank of a vehicle. The method includes molding a plastic flange 12 of a fuel delivery module, with the flange defining an inside region 11 and an outside region 7. At least one terminal 20' is provided that is accessible from the outside region of the flange. An electrical connection 28 is established between the at least one terminal and a wire 16'. In one embodiment, plastic material 25 is molded directly over a) the connection 28, b) at least a portion 32 of the wire 16' and c) at least a portion 34 of the terminal 20' to seal the connection, the portion of the wire, and the portion of the terminal between the inside region and outside region of the flange. In another embodiment a pre-formed plastic body encapsulates the connection 28 and the body is placed in a flange mold and plastic material is over molded to encapsulate the portion of the terminal while molding the flange.
