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

Its an acquired taste...similar to licorice
I don't like licorice

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".

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?



I have been running those 22psi bypass, i like them very much
On a side note; i won't run the Mobil one filters any longer.
they bypass sucks from the bottom, and with the filter hanging straight down...
Wix filters bypass from the top, my new go-to.
also my filter opening tool is awesome, i'm learning so much.
and every wix filter i open, i get a little surprise inside!
What you might ask?
A coil spring that goes into my "might need it later for something" bin.![]()

Out with the old, in with the new!
No surprise, it was the high pressure hose. It was tricky getting that crazy-shaped hose connected on both ends. Nobody online can tell if they use 5/8th or 16mm. I just used an adjustable crescent wrench and crammed my long arms up in there from beneath the car.
No more leaks and I can steer again!
Thankfully the one bolt sealed enough that false air was not being sucked in for the sensor to read and mess with fuel mixture.When I fired it up in the garage to move it to the shop for the service, it had what sounded like a minor exhaust leak. Once in the shop, I popped the hood and inspected the manifold bolts- all there. Then I noticed the flange was missing a bolt:

Under it, I realized it was actually missing TWO of the three bolts:

These must seal really well cuz the tick wasn't very loud at all.
Since Doug Thorley sent two bags of hardware, gaskets, etc. with the headers, I had extra bolts to replace them. The exhaust pipe was also bumping the crossmember again even though I had adjusted the hanger at the last service. I now realize it was just sagging from all the extra slack. I raised the exhaust more by adjusting the hanger and supported the pipe even further with a wedge on top of the crossmember. When I tightened the bolts, the wedge fell out. It should be good from now on.

Been using WIX for over 30 years and I have cut them open too. Cut open a FRAM at the time and the filter element had string tied around it at the middle to control the filter element bulge and if I remember right it had a very weak coiled flat steel spring that could easily be compressed fully with your thumb and two fingers. Many shops had displays of the comparisons of the filter quality. It was a no brainer for the vehicle customers in my shops.
I thought the K&N were better all around (psi and micron)?It's like a grease monkey's Cräcker Jack prize!
That's good to know about the WIX's bypass setup.

Nevermind…I just answered my own question. Be quiet, be humble, admit when you’re wrong and learn something new. Damnit!
How did ACD, M1 and K&N lose out to Wix? Probably because they are all now manufactured in China?
Instead of a long typed response, here is the jest of it:What's the importance of the oil filter bypass? And about the psi that the bypass opens?
