I'm a little late to the party however, if your hood clearance permits, consider adding a carb spacer/insulator.

Another simple solution is "T" off of the rear, secondary carb feed line. This added outlet coming off the carb feed line can then either be ran back to the 1/4" port on the sending unit or use a fuel filter with an added port such as Fram filter G3499 and run the return to the filter. If you run it back to the tank, this provides a loop or circulating fuel system.
