Today’sfuels are partially to blame as they have a higher Reid vapor pressure, so evaporate more easily than the gasoline back in the day. Manifold heat isolator help somewhat but not that much. I installed switches so I can turn my fuel pump off a block or two before parking the car and then let it idle a bit to lower the fuel level in the float bowls. Unfortunately, short of hooking up a hose as you suggested, I think that’s about all you can do.
