Is there a place you can put remaining fuel on a trip? I was on a run and was wondering how far I could go with remaining fuel. and you put that on your gauges? And how.
The tank is supposed to be 18.5 gals, I estimate 18.0 to the first click-off with most pumps.
I calibrated my gauge by noting how much fuel it took for the pump to click off the first time and subtracting that from 18.0
Do this several times at several different pumps, and average the results.
I look at the "fuel used" read out at every fill up since I don't trust the pump to shut off if I am doing things to override the constant shut-off problem.

And btw, fuel is used as ambient coolant for your fuel pump. I would not be stretching to see how far I can make it to the next gas pump - you are stressing it for no reason.

I have a million plus miles of experience with cars. One car with 480k and others from 150k and up. All driven till empty on the gauge. I have replaced 3 pumps in the last 30 years. 2 of them were for performance reasons and 1 was working fine but the sender died but it still pumped. Will that lore ever die?

Ok fair point, the reality is this guy in this case with a stock car will "most likely" never have an issue with his pump doing this - a lot of redundancy goes into the design of a critical system, rightfully so and what you are describing above. However, it is still putting more stress on the components running it hotter as opposed to a keeping fuel in the tank - that is not lore. The pumps are engineered/designed to be ambiently cooled by the fuel in the tank. When you start commanding more from the fuel system, this becomes apparent. Ask the guys smoking their fore systems by doing this exact thing. Less redundancy designed in lieu of more output, but the principle remains the same.

Take a look at THIS and keep going down to see the test. In this test of an old pump, it is rigged to fail since it has no fuel running through it. IDK if the pump spins faster since there is no load. There is also no fuel cooling it via heat transfer to the fuel as it goes through the pump. Neither of these things will happen during running conditions since the engine dies if you run out of fuel and the pump will stop.
Someone had posted that most of the fuel pump cooling is from fuel going through the pump, not the fuel sloshing around it.
I can't verify that.
Question. Seeing as how the plastic tank isn't a good conductor of heat, would it be a good idea to use the fuel as a coolant? Obviously, the fuel will pick up some heat but I would think that you would rather run the heat to the fuel injector as much as possible. I think it is like the old multec injectors that run fuel past the coils for cooling before the fuel hits the cylinders.
