That is why I am adding a control valve, so I can turn it off. I may find in winter I don't need it beyond warm up and I may not want it on at all in the summer.

This normally happens any ways when you have a typical non-divorced style intake manifold. I have seen the carb on my Camaro showing roughly 200'F with the factory style intake where the bottom the plenum and intake runners are the top of the inside of the lifter valley, so it gets pretty warm.
Vapor lock happens when you get vapor bubbles in the fuel lines from the fuel lines getting too hot. Most amateur hot fuel experiments try to heat the fuel line, this rig only heats the fuel once it has reached the carb.
I can prevent baking the fuel once its in the carb by turning off the coolant a mile or 2 before I get to where I am going and cutting off the fuel pump to burn off fuel in the bowls.

Normally coming from me it would be a bash thread.
