ABSTRACT:
A coupling for connecting a fuel delivery conduit to the discharge opening of a diesel fuel tank includes a hollow fitting body defining a flow passage in which is located an electric heating rod for heating the fuel as it flow through the passage from the tank to the conduit to prevent waxing of the fuel at low temperatures. A passive heat transfer member, which may be a solid metal rod or an elongated cylindrical heat pipe, is thermally and mechanically coupled at one end to the heating rod and is of sufficient length and is so arranged that its other end extends into the tank through the discharge opening for directing a portion of the heat to the fuel near the discharge opening. On tanks provided with an internal draw tube communicating with the discharge opening, the heat transfer member is designed to extend through the draw tube into the tank and the heat transfer member may be provided with a sleeve of thermal insulation over a portion of the length of the member to focus heat transfer therefrom to the other end thereof.
