Abstract: A fuel tank assembly includes a fuel tank and a coupling assembly for coupling the fuel tank to the underbody of a vehicle. The fuel tank includes a tank body and a plurality of tabs extending from the tank body. Each tab has a tab opening. The coupling assembly includes at least one strap partially surrounding the fuel tank. The strap defines a strap opening. The coupling assembly further includes at least one fastener extending through the strap opening and the tab opening. Further, the coupling assembly includes a compression sleeve partially positioned in the tab opening. The compression sleeve defines a sleeve opening for receiving the fastener. The compression sleeve has a height that is greater than the height of each of the tabs in order to attenuate the transfer of tensile loads from the at least one strap to the tabs.

Abstract: In accordance with an exemplary embodiment, an emission control system and method is provided for a vehicle. The system comprises a reductant reservoir having an intake pipe for receiving reductant and a heater for heating the reductant. A pump provides the heated reductant to an injector and also to a conduit extending into the intake pipe to provide heated reductant into the intake pipe to melt any frozen reductant in the intake pipe. The method comprises heating reductant stored within a reservoir of a vehicle emission control system, and pumping the heated reductant into an intake pipe of the reservoir to melt any frozen reductant in the intake pipe.

Abstract: Methods and apparatus are provided for installing a fuel delivery system in a vehicle fuel tank of the type having a sender opening extending through a top of the tank, a flange cover configured to seal the sender opening, and a sender module mounted within the fuel tank. The sender module includes a fuel pump, a fuel inlet for drawing fuel from the bottom of the tank, a fuel outlet, and a detector module for detecting the fuel level in the tank. A coupling assembly includes an electrical conduit for transferring a fuel level signal to the flange cover, and a hydraulic conduit for transferring fuel from the pump to the flange cover. A retainer is mounted to the bottom of the fuel tank, preferably laterally offset from the vertical axis of the flange cover, and secures the sender module to the tank bottom.

Abstract: A reductant reservoir for an emission control system has a pump assembly with an intake adapted to withdraw reductant from the reservoir, a heating element associated with the pump assembly for heating reductant and an outlet for delivering heated reductant to the emission control system. A nozzle assembly ejects a portion of heated reductant into the reservoir to thaw frozen reductant.

Abstract: A flow-restricting plug is provided for installation within a vapor recirculation pipe that communicates with a fuel filler pipe. The plug is manufactured of fuel-impervious material and has a cylindrical shape adapted to be mounted by press fit within the vapor recirculation pipe. A flow passage of tortuous shape is formed along the outer circumferential surface of the plug between the opposed ends thereof. The tortuous shape of the flow passage permits the flow of fuel vapor through the plug but prevents the flow of liquid fuel through the plug.
