...I have experienced vapor lock on a vehicle with in tanks pumps. That was at 100 + degrees in the desert on some no name road with no place to hide out of the sun until the vehicle cooled down. ...In tank pumps while a better idea, are no guarantee against vapor lock.
In-tank pumps are the best you are going to do. If that vehicle had a mechanical pump exterior to the tank, you would have been there with no place to hide out of the sun for several hours instead of just one.
