Abstract: A fuel filler tube assembly is provided and may include a filler tube having a tubular body defining an inlet larger than an outlet and a funnel insert having a first cylindrical section, a second cylindrical section, and a third cylindrical section disposed between the first cylindrical section and the second cylindrical section. The first cylindrical section may be received in the inlet of the filler tube with the inlet engaging the insert between the first cylindrical section and the third cylindrical section when the first cylindrical section is disposed within the inlet of the filler tube.

Abstract: A fuel filler assembly includes a filler tube including a tube inlet having a larger diameter than a tube outlet and a transition portion disposed between the tube inlet and the tube outlet. An insert is received by the tube inlet and includes an insert inlet and an insert outlet. The insert outlet is received by the tube inlet and includes a nozzle opening axially offset from a central axis of at least one of the tube inlet, the insert inlet, and the insert outlet. The nozzle opening positions a nozzle received by the nozzle opening to direct supplied fuel toward the transition portion of the filler tube.

Abstract: A method of forming a filler tube includes forming a funnel insert, forming a funnel portion in a first end of a filler tube, and joining the funnel insert and the funnel portion of the filler tube. The funnel portion includes a transition portion configured to induce a swirl to passing fuel for venting vapors from the gas tank during fuel filling. A fuel filler tube assembly includes the funnel portion including a tubular body defining a larger inlet and a smaller outlet, the position of the inlet relative the outlet and an internal configuration of the tubular body therebetween inducing a swirl to inventing vapors from fuel flowing through the tubular body. The larger inlet receives a funnel insert including a nozzle opening positioned to cooperate with the internal configuration of the tubular body.

Abstract: Two unique quick connect fluid coupling embodiments have a tube inner end which does not contact a seal if the tube is not fully connected. Preferably, a retainer retains the tube within the bore. The retainer is of the avalanche type such that a high force is required to insert the tube, and once this high force is overcome the momentum of the tube carries it to its fully inserted position. No seal is formed between the tube and seals within the housing unless the tube has moved beyond the avalanche point where the high force begins. Once the tube has moved beyond that point, it will be fully connected. The invention ensures that there would be no seal between a tube and a housing unless the tube is fully connected.
