Abstract: A fixture for assembling a coupling assembly is provided. The fixture includes a base member having a top surface and a bottom surface distal to the top surface. The base member is configured to receive the coupling assembly on the top surface. A plurality of projections extends from the top surface of the base member. Each projection defines a hollow portion configured to receive a bolt head of a corresponding bolt of the plurality of bolts. The hollow portion has a shape complementary to a shape of the bolt head to rotationally restrict the corresponding bolt relative to the opening of the coupling assembly. A support member is mounted on the bottom surface of the base member and configured to position the base member at an elevated position with respect to a working surface.

Abstract: A dual temperature valve positioned in a bypass passageway can move to an open position when two temperature conditions are met. When opened, the dual temperature valve can allow warm fluid from a first line to mix with cold fluid from a second line to heat the same. The valve is preferably utilized in an engine fuel system and positioned in a bypass passageway extending between a fuel supply line and a fuel return line. In this application, the dual temperature valve can prevent possible fuel transfer problems, such as cold start gaseous circulation.
