Denny, BigKev made two excellent suggestions, and let me add a third. Many models used fibre insulators around the fuel pump-to-block bolts, and a heat shield around the fuel pump. Some other models also used an insulator block between the fuel pump and the block. The purpose of these were to prevent heat from the engine block from heating the fuel pump and such heat can then be transferred by the metal fuel lines to the carburetor and indeed the entire fuel system. Rubber links in the line to the tank, for example for an inline filter or electric pump, can exaggerate the problem by eliminating the gas tank and its contents as a heat sink. I suggest you check the parts book to see if these items were used for your particular model, and if so check and make sure they are present.
