what is the difference

It's running with factory fuel line, I believe it was or is a holley 85 gph mech pump. Jets, I can't remember off the top of my head, I'll get those numbers tomorrow. The carb is a quick fuel 650. It ran great in the cooler weather but I ran the other day in 80 plus temp and it just fell over on the last 3-400 ft.. I have a fuel guage on it set to 6psi. Also I have a new 140gph elec pump and 1/2 fuel line going in this week.
