The fuel is vaporizing due to heat from the OE fuel line on the pass side of engine bay is next to the exhaust. Reroute it away.
You might consider running a return line back to the fill tube, that little piece behind the license plate is a good spot for hooking up a return line, and install a fuel regulator, ie., Holley type. Adjust the fuel for 6-7 psi, from the secondary side, one side to carb, the other secondary outlet to the tank.
This will keep the fuel cool.
