Here is an update. I got a 3' piece of Thermo-Tec sleeving that is supposed to reflect 90% of radiant heat and slipped it over my fuel line from the pump to the line near the collector.

I haven't had the chance to go for an extended drive today to test the issue but I did idle car in the garage for maybe 15 minutes until it was good and hot and made note of the temps on the fuel bowls and lines. Granted the hood was open but the fuel bowls were at 115* and the SS braided lines were about the same (down from 165*).

I also noticed that the fuel pressure after shutoff took about an hour to start bleeding down as was still at 3psi on my gauge several hours later! Before the sleeve it would bleed down after a few minutes. I am hoping this bodes well for curing possible vapor lock issues.
