The fuel line gets over 300 deg. after I shut off the engine. If I let the car set 15 minutes it won't start. Or starts very rough. Then after it cools down no problem.
So I drove it to a different State that did not have ethanol and tried their gas and it does not vaporlock.
I'm thinking of either adding a second fuel pump on the return line that would help perge the system of vapor. Then as soon as the engine starts it would turn off.

Vapor lock is the result of the fuel lines running close to the exhaust manifold heating up when the car is not moving and there is no airflow to disperse the heat. The easiest way to fix it is to insulate the fuel line, move it further away from the exhaust manifold or install a heat shield between them.
Any one, or a combination of these will fix your problem...

If you can find the line in question, you could insulate it, or otherwise shield it from the heat. An octane boosting additive might help also, but I'm not sure. For $3, you might as well try it before spending a lot of money.
