Bypass vs Deadhead fuel pressure regulator question.

If vapor lock is a consideration, getting rid of the Edelbrock carb is the first place to start. They have small float bowls that pick up alot of heat from the engine. I have a dead head system on my 64 Sport Fury using a Carter pump, and 1/2 inch line to the regulator. Then 3/8 line to each bowl. No issues.
