Fuel Cooling the Fuel Pump Question

We've been over this before. The fuel pump has a "bath tub" around it that is constantly filled from the pump and over flows out of the top. The pump will not consume the fuel inside the tub. It is always full even when you are low or run out of fuel. This is not a new design and has been around for decades. You can run your tank down until the low fuel light comes on for hundreds of thousands of miles and it won't make any difference.

 

In any event, do you really want to run out of gas if let’s say there’s a run on fuel? There’s been a lot of times that’s happened in the past few years during major events. Hurricanes, blizzards, etc. ....Keep your baby fueled and you never have to worry about it. Me personally, I never let my tank drop below half

 

Thanks To consider the fuel pump actually is submersed in fuel is an important point in this discussion. The pic was a good idea too. To anyone who wants to point out 3-5 gallons will provide more cooling than a gallon or less, thats true, but the question would be then, just how much? Is it enough to make a difference? My opinion currently is it's not, which has been bolstered by the above quote.

 

How about $2 a gallon difference? That is an extreme example but that is often the difference in price from Furnace Creek in Death Valley and Parump or Beatty in Nevada. On long trips I'll often find around a dollar a gallon difference, and I'm cheap enough to pay attention to 10 cents a gallon. At some point on every multiple day trip I've taken driving 60 -75 miles more has made a difference in the price of gas. Since I put around 20,000 miles a year on my Tacoma that makes a difference.
