This video might be of some help for heat soak vapor lock problems. I have not tried it but it seems to make sense.

Vapor lock
Re: Vapor lock
Ken,
Looks like neat stuff to try. The good news is that if it doesn't work, it doesn't break the bank. If one of my toys still had a carb, I'd certainly try it; I tried everything else
I did try a fuel pressure regulator with a return line (also way more than $8) but it didn't work either. Theoretically it should have, but who knows?
As you know, EFI solved all these problems for both my cars, but it cost way more than $8.
