I have ruled out leaky injectors, definitively.

How do you know it's vapor lock?  Have you ruled out leaking
injectors?

I've tried a bunch of things to relieve my vapor lock and it's still
bad. I keep fumbling with the residual pressure valve, but the fact
of vapor lock still remains. In city driving, it's very noticeable,
but mostly after sitting for 1/2 hour. I have to use "special"
starting procedure to get the car running and purge the fuel ines
with cooler fuel.

I have my injector cooling fan running. I do use a lower temp switch
mounted elsewhere. Afterrun works. The rubber boot for the hoses is
there. I wrapped it with foil tape. It helped some, but not that
much. Anyone been here before and what did you do? I'm going to try
and shim the lines from the intake manifold with some silicone
strips to see what happens. I can raise the residual pressure, but
that'll leave me with harder starting, but the + is that it'll start
every time.

Any ideas?
