I can wait…
Yup. I drained about two-three quarts before I collected my sample.

I don't like licorice
Its an acquired taste...similar to licorice
Cake gives some girls the farts…
I wonder how far you were from burning up the pump. A lot of people don’t realize that “normally” other than instances like yours, the only reason a fuel pump goes bad is from people driving their vehicles with low/no gas in them. Otherwise if the fuel pump is submerged it will keep on keeping on. My 02’ has 360k+ miles and never has had the fuel pump replaced. I changed the fuel filter quite often and tried myI tested the level sensor on the original fuel pump module. Full was 40.x ohms, as it should be. As I slowly lowered the float arm, the impedance increased fairly smoothly until it reached a maximum of 193.8 ohms with a considerable amount of travel left in the float arm. Moving the arm further resulted in an open circuit for the rest of its travel. It's supposed to operate on a 40 ohms (full) to 250 ohms (empty).
193 is 77.2% of 250. 100% - 77.2% is 22.8%, which is a little under 25% or 1/4 tank. Just under 1/4 tank (per the gauge) is where it really started acting up when accelerating.
So, this means that when my gauge read ~1/4, I actually had anywhere from just under 1/4 tank of fuel to fumes remaining.
What I don't get is why the gauge didn't just suddenly plummet to "E" soon after that ~1/4 tank mark. Perhaps the PCM has backup logic to override the analog sensor in case of a failure? It could estimate the fuel remaining by factoring the last known quantity and injector duty cycle.
I guess I'm gonna have to fill one of my race jugs and go for a drive to see where it stalls. I could put three gallons in the jug and when the Tahoe runs out of fuel, that three gallons plus whatever is still in the tank should put the gauge right around the 1/8th tank mark. I'd know the accuracy of my gauge as well as my "stall point".

best to not let it fall under 1/4 tank.
Nice work on the Big 3 cables. Did you wrap your starter cable as well? Mine was getting pretty hot, so I used a heat shield and wrapped not only the starter but also the harness running into it and the battery cable as well.
Hows the new rad holding up? Did you end up changing out the fan(s) yet or still running stock?
