There are also fuel pump gaskets made to reduce heat transfer, just have to make sure you don't use one that's too thick. I don't run one yet tho.
I have a mechanical pump with a return but after heat soak (45misn of driving) my AFR gets about a ratio and a half leaner. I have a wooden spacer under my carb and heat shielding around my hardline from the pump up to the carb.
When I do my new heads/cam/intake/pistons this winter I'm just throwing in the towel and going Holley EFI.
