Try insulating the fuel line. Products-204002-Shield-Sleeve/dp/B004GNLGTQ? tag=askcomdelta-20


If your sure it is a vapor lock and not a fuel tank venting problem there is some fuel line wrap that is very good at diverting heat away from the fuel lines, it looks like the same stuff a fireproof suit is made of, the drawback is it's hard to put on and cover all the fuel line.


Make sure the engine is simply not running too hot and if so deal with the cooling system but tennis has a good idea you should check out.
