Ok guys I'm looking for new ideas on vapor lock issue here as I'm about out of them.

Truck is a 1985 K30 with a 572 big block in it.

I've done the following which has helped some but it is not completely gone as it has done it at least three times this year.

Spacer under eldebrock carb
GM shield under carb
wrapped gas lines
bigger radiator fan
cowl hood
open air cleaner element

The truck does have dual fuel tanks. Should I try a high pressure fuel injection pumps with that recirculating line? And put a fuel pressure regulator before carb? I'm not sure this would all help or not?

I'm open to any suggestions.......

Thanks
