I think Tony knows the fuel is receiving heat. The point is it is such a miniscule amount that you probably wouldn't even be able to measure a difference in temperature.

Well yeah but aren't you increasing flow to the HPFP? And that system has no return so while you could theoretically increase flow once you hook it up to the car you will only get what the HPFP allows. I mean its great to say you could theoretically flow xyz. But, until you actually hook it up to the car and try it you don't know what it will do.
