How do I stop vapor lock?

True vapor lock usually comes from heat soak conditions. Hot day you run the car hard then stop for 20-45 minutes. You come back out car starts fine and you go about a block and the car stalls and won't restart. Fuel in the pump vaporizes from the heat soak so the pump won't pump fuel. It starts and runs on the fuel remaining in the fuel bowls.

Check the fuel cap, filter and sender sock. Good Luck.
