Possible vapor lock problem

I have a 71 c10, 350 gm crate and motor with edelbrock 1406 carb. I run a Quick fuel electric pump with pressure regulator set at 5 1/2 psi. I have been experiencing pressure drops in the afternoons when its hot while in traffic. Once i start moving pressure goes back to normal. Would a return style revulator help with problem? Would running 93 octane help?
