How do I stop vapor lock?

I got back a few hours ago and am settled back in. It didn't sputter, miss or cut out on me once. All the way up and all the way back. It did fine. I did move the fuel line away from near the block, water pump, and alternator and put it on the fender well, running it over the alternator with a bracket I made. It did great until I punched it close to home. Then it died, but came back to life before I came to a stop. I'm' thinkin maybe the post was right about winter fuel is begging too much to vaporize and since it is around 70 degrees when it vapor locks, that may be what is doing it.

Would a cap fix this situation? I have an old old ooooooooooooold locking gas cap on there that never caused a problem before, but maybe it is tooo old!

I haven't found a good cap replacement yet. The one I ordered the guy at the parts house said it was an OEM when I ordered it. When I went to pick it up, it wasn't OEM!!! Argh! I hate that.

Anyway, anyone know a good place to get an OEM gas cap for my Duster (1970)

Why did someone say an electronic fuel pump would be a solution? What is the difference between the mech. one I have on there and an electric one? Would it be the location it is in that would keep it from getting hot like the mechanical one?

Thanks!:cheers:
