Somthing else occurred to me as I sat in traffic today watching my temp guage climb and listening to my almost new pump start to make a racket. I was down to about 1/3 of a tank and have recently added the bottom baffle plate (missing on early cars), and properly routed the fuel drain back to the baffle. The fuel pump is drawing the same fuel over and over from the very small reservoir that is the baffle. I would not be at all surprised if the fuel in the baffle is considerably hotter than in the surrounding tank when you are in traffic as a) you're not using much of the fuel being pumped round and b) the fuel will not be agitated much. I have noticed a marked increase in the noise of my pump since adding the drain hose rather than just letting it drop back into the tank as I had it before.
