How do I stop vapor lock?

Install heat sheild around the fuel line coming to the pump and from the pump. Especially where it runs between the header and the frame rail. Manual pump cannot pump boiling ethanol. You can buy rols of it at any speed shop. You can see it on my fuel line below it is a silver slip on heat sheild.

This is my next step as I see it. I think the problem is the fuel itself. I never had this problem before running mopars for 30 years. 33 years. The fuel lines and pumps have remained the same the whole time. Just now it started happening out of the blue. I will get some heat shield and put it between the header and the fuel line, and where it comes up between the alt, water pump and block. I re-routed it to go around that location and it helped a lot. Still have prob at WOT when it runs the fuel out of the bowls. It died again, but only long enough to get fuel to the carb again. It is either the fuel bowl adjustment or the ethanol evaporating too soon. But I really do think it is the ethanol.

Thanks...
