Should I dare thread into this, why not? Fuel supply systems are most susceptible to vapor lock in the unpressurized part of the system. That is, the line from the tank to the pump, for those systems without an electric fuel pump. The line from the outlet of the pump to the carburetor is the most unlikely part of the system to experience vapor locking. Fuel in the carburetor, which is not under pressure, can easily vaporize due to heat coming up from the engine. Locating an electric fuel pump as close to the gas tank is so that as much of the fuel supply system will be under pressure as possible. This is not because, as commonly believed, an electric fuel pump functions better as a pusher. It's late and I need to go to bed. Good night and count your clothes pins instead of sheep. Zzzzzzz...
