Observations
One of the benefits of being my age, and having 30+ years of automotive technical writing experience, is that I've developed a significant log of professionals, to whom I can go to ask a question. Those who've read my magazine work know that I often say, "Don't believe this because I said it; believe it because 'xxx' who deals with this daily said so." With that firmly in mind, accept that I make sure that I have a firm grasp on the technicalities of what I write.
Sources within FoMoCo have confirmed my belief that the cooling aspects of the location of the pump assembly within the tank are entirely secondary. It would, obviously, be incorrect to say that there's NO pump cooling done by the gasoline. However, my contention has been, and remains, that it's a side issue. As long as there is gas flowing through the pump, all necessary cooling is taking place. The location of the pump, in the tank, is primarily because the mass of the fluid helps make the pump run very quietly. No more than a glance at an in-tank pump assembly, or even a photo thereof, will make the lay-out of that pump assembly clear. (And as an aside, the pump I use to run methanol is a stand-alone that CAN be installed either in a tank or not. The pictures in my thread---'Land Speed LS'---will show the pump, heavily clad in roll-bar padding, setting next to the fuel cell. Believe me that it's very audible.)
As to being kidded, I've looked back at the posts above, and realize that, perhaps, my replies come off as somewhat of an over-reaction. I'll strongly defend what I said, but the tone may have been somewhat heavy. In regard to the snarkiness, I consider the source.
To speak to what you've styled as self-promotion, I have nothing to promote. Others here either ignore a question that's been covered and re-covered, or deign to grumpily suggest a search. I have chosen to try to be helpful and, instead of repeating myself, I tell the questioner to look where the information can be found. I am not trying to sell anything. I appreciate your avuncularity.
My record speaks for itself. (My thanks to those who've PM 'd me on the above subject.)
One good thing about the written word---If you don't like it, don't read it!!!
