ABSTRACT:
An in the tank fuel line heating system for heating the fuel as it is removed from the tank includes a fuel outlet conduit communicating with the port in the tank and extending downwardly into the tank to a point substantially near the bottom of the tank. A coolant circulating conduit is located adjacent the fuel outlet conduit and serves to transfer heat from the engine heated coolant to the fuel in the fuel outlet conduit. A fuel return conduit is provided adjacent the fuel outlet conduit and serves to transfer heat from the unused fuel returning to the tank to the fuel exiting the tank in the fuel outlet conduit. The coolant circulating conduit is provided with an extension that extends along the bottom of the tank and prevents ice build-up in the area.
