Filled up with better gas and drove. A difference already, Tomorrow back to driving to work for another test and i am going to insulate the gas line with what Tom is sending me. But look at the difference in the gas caps. The REPO which has the vent is larger and more sturdy. Wondering how exactly the VENT helps the vapor lock to prevent it??

What you have is a radiator cap being used as a gas cap. They are both the same in looks but work exactly opposite. I didn't think you had a vapor lock when you first posted before but, I am a naysayer. To see what will happen with your scenerio, use a half tank of gas and put a layer or two of saran wrap on the filler and hold it in place with a rubber band. If you get more than 2 miles before the car quits you will be lucky. 3 miles would be almost impossible. Try this after you insulate the fuel line and you will see.
