Good tip David but when it is that hot out, you should have your blower running all the time and when you shut her off to float for a while, open the engine compartment cover for a good 5-10 minutes to let the heat escape. Following the above, I have never had vapor lock happen to me.

Also, when you open the engine compartment to feel the fuel pump right after you shut it off, I think it's always going to feel cool since it just had fuel running through it. It's when it sits idle that it absorbs the heat from the engine compartment causing the fuel in the pump to vaporize. So perhaps opening the engine compartment is what actually prevented vapor lock from occuring again, not moving the oil hose away, although I am sure that helped as well.
