You almost never hear of a modern car getting vapor locked because of where the fuel pump is located. When the pump was at the engine as it used to be it had to pull the gas from the tank and then push it to the carburetor. If there was vapor in the line between the tank and the pump, or within the pump, the engine would stop because the pump couldn't pull on the vapor. Now that the pump is actually inside the gas tank it doesn't have to pull the gas for any measurable distance. If a vapor bubble were to develop in the line between the tank and the engine the pump would keep on pushing gas and the bubble would be compressed and the engine might sputter a little as the bubble was ingested but it wouldn't stop.
