From what you said, you have the electric pump toward the front of the car. Or is that the mechanical one? What is the fuel pressure? Do you have a gauge? Do you have a filter before the pump?
No electric pump just mechanical. I think i got the vapor lock issue solved. filter before the pump. fuel pressure is set with a holley regulator to 6.5 pounds(it maxes out at 8 so we are good there)
