The BDRs have a second cap (vented) under the quick fill.
The problem the OP has is thermal expansion of the fuel and overfilling the tank.
The vent line and filler pipe pick off the tank at almost the same location on the side of the tank. The vent is connect to the filler pipe approx 4" from the top.
Since the vent line is positioned on the inboard side of the filler neck 4" down the issue is aggravated when you stand to the side of the car and point the fuel nozzle inboard. It can cause splashback and fills the vent line.
Safer to have the nozzle pointing forward.
When the car is overfilled, fuel will be in the fill pipe and vent line. After a few turns and stops and starts the tank will be burped of all air and the fill pipe and vent line will still have fuel in it. Then comes the thermal expansion of the fuel. Cold underground tanks and a warm fuel tank in your car.
Buying fuel from a busy station is less of an issue than a Mom & Pops station as far as getting cold fuel.

In aviation we don't fill our jets in the morning to the caps and leave them in the sun. Makes a huge mess. We use a "summer load", 3-4" down from the caps.
