The breakdowns just add to the realism of owning a supercar.  "Oh look...he broke down...must be a real one!"   ::toothy

The three normal solutions would be to re-route your fuel lines to minimize heat absorption, improve airflow across the engine bay and, if you are running a mechanical fuel pump, switch to an electric fuel pump (in tank or close to tank depending on your setup.)

SBC V8 carbureted engine Vapor lock issue
« Reply #1 on: June 27, 2016, 02:35:28 PM »
The new blend of gas out there with its lower boiling point has created many embarrassing moments for me.
When you pull up to a stop light and your car stalls, then you have to wait for a while for the engine to cool down and start the car again.
I have tried to have better engine air flow but still limited to cooling the engine bay in my Diablo.

What are others doing to resolve the Vapor lock issue with this new stupid blend of gas and Carb engines....
I am sure this is also an issue for the older Street rods/Hot Rods out there.

Any advice is greatly appreciated
