Finally found the info on the GMT 900 dual tank set up for a 2011 6.0L L96 1T truck. This is also the same info as the 3/4T Suburban, Whoa …. Lotta info
Replace 31 gallon tank with 39 gallon tank from 2500 series Suburban?

I gave them a ring about 2 years ago. Ty for the link. They can manufacture or make almost anything however, they’re not allowed to sell it. Kinda like prohibition on booze, but for gas tanks.
They suggested having a shop custom make one as the only option. He said most shops wouldn’t accept the liability though.

Can't fix stupid
Years ago I thought about taking a boat fuel tank and mounting it in the back of my blazer.
From there I could just pipe in a fuel line and a fuel pump to add fuel down the filler neck.
options would be to bag the tank and run a remote vent to prevent fumes...
In the end I just made a hitch carrier and mounted some Jerry cans to it.
Now for the tahoe, I have an actual hitch carrier.
My Jeep, I bought a rear bumper that has jerry can mounts built in.
My blazer had terrible range, it nearly got me in some trouble once...
Same area as where I own a few acres now, with the Tahoe I can top off at the last stop and get there with 3/4 of a tank.
Then I need half of that to get home or top off at the same pos out in the middle of nowhere place that says it's premium, but the Tahoe disagrees.
Yeah, I'm good with as little gas as possible from that place.
I love the Jeeps setup, I want it on my Tahoe, a back bumper to carry a full-size spare, and or gas cans.

I sputtered into Gila Bend when coming out of NM from AZ. A long âss strip of desert that will get you stuck in the sand if you pull off the road and no cell signal.
Never so happy in all my life to see that truck stop pop up on the drive from TX to SoCal. Our trucks tank holds 31 gal and when your fuel sender is working like it should it keeps you outta trouble.
Most of our 07-14 truck are coming due for the first time to replace the fuel pump & sender. The poor folks who install all those overseas counterfeit parts the first time are really screwed because the junk pumps slowly die after 12-18 Mo’s and owners expect its something else.
It’s common on the 12-14 Escalade Premium & Platinum trim to have no spare tire. They had the dual exhaust option that took its place. I’d give up my spare for a larger or 2nd tank even if it was only 8-12 gal.

Thanks for the definitive reply. Maybe I should leave it as is. All the viable solutions are not cost-effective, short of getting a 2500 series Suburban (which comes with the 6.0L versus 6.2L).
The remaining question is, how do I caliberate the gauge gauge to correctly read empty when it really is empty. I have never put more than 26 gallons in it, even when the gauge dips below the horizonal line and looks scary like it will stall any second now.
Do I need a different fuel pump? Or some other device along the way to the gauge?
Actually an interesting idea would be to install an aftermarket gas gauge, how hard / expensive would that be? The default one positively sucks. It's the size of the half-dollar and doesn't show any granularity.

I know people who used to bend the fuel level wire on the float to adjust how they read. I don't get more than 26 gallons unless I really run it down.
When the light comes on, if I fuel up right away, it will take high 24s or up to mid 25s for fuel. Drive for an hour afterwards and she goes 26-27 gallons. Like tomorrow!
Light came on when I left the house tonight, drove 36 miles to dinner and back and will refuel later today.
I reckon the longer tank spreads the fuel out making our useful capacity not much more than the 26 gallon guys. My kids have 26 gallon tanks in their pickups and always put 25-26 gallons in them.
When the tanks are this low, the fuel float can read 0% and move around to 8-11% but the pump is submerged in a bath of fuel regardless.
The Tech-2 can show you the fuel pumps Long Term Trim which I guess is a condition of its health. Last time I checked mine, it was moving up a down a couple of points but has steadily gotten higher over the years. It's much higher than my pickup which just turned 110K miles. I have a brand new unit with all the trimmings sitting on the shelf for when I'm ready to change or it gives up the ghost. Still holds fuel pressure while driving at 42-44 psi.

Pumped aboard 28.3 gallons just now, Torque Pro app showed 92% full when driving. Usually shows in the 80s with a 25 gallon fill. That was 44 miles of additional driving since the light came on last evening. It's consistent and predictable.
So the good thing is, it has a very generous reserve.
