How do I stop vapor lock?

After re-routing the fuel line, it is not hard to start when hot now. It was very hard to start before re-routing the fuel line to avoid going up the front of the motor.

I could try a cooling can, but for long trips it may not be practical. It would work for around here on hot days though. We get 100+ during the summer, though I don't like to drive it in that hot of weather.

I haven't had the opportunity to try running WOT without the gas cap yet.

There is a vent at the top of the filler tube inside the trunk. It is not open. Is it supposed to be?? There is also a vent tube at the sending unit that is not open. Is that supposed to go to a vented filter?

Thanks!
