S&B 60 gal tank

There's no way I could do this in my truck, I have had it say I have 75-100mi DTE and filled up with 57.5 gallons. I have reprogrammed the tank size with ForScan and did the PCM/IPC change, as well as AFE Bias calibration. 100mi is my zero now.
That’s interesting. It’s been quite a while now and although I don’t go down to zero, I still fill up around 50-75 DTE and I’m still only putting in bait 52-54 gallons at that time, so I could still use zero as my fill up point, but just don’t like to push it

it's very weird, makes no sense to me, seems to be an issue with a few people. Maybe I should convert it back to a 32g tank lol

Example: I filled up yesterday with 52.837 gallons and the fuel gauge was just under a 1/4 tank showing 200mi DTE.

Has your computer vs hand calculated MPG been the same since you did AFE bias adjustment? Mine has been exact most of the time, and the few times it’s off, it’s only been 0.1. That’s the only thing I could think would cause the DTE to be off vs the gas remaining. But either way, as long as we know what our real numbers are, I love having the large tank.

Yes, it's still typically ± 0.1 - 0.2 with fuelly.
The dte got worse when I tried resetting it via ForScan with a full tank. When I first installed the tank and did the recalc it was still very empty, the 5gal they put in it to not have an empty tank.

I later changed it to a 58 gallon to try and give me back that headroom and seemed to be worse that fuel tank so I set it back to 60g
 
Would be pretty cool to have a setup like this to measure actual fuel consumption:

"Has anyone done any decent offroading with this thing, or been in deep snow/sand where the clearance could be an issue? What has you experience been in those circumstances?"

I've done a fair bit. The diffs are what usually scrape.
This truck is never gunna do more than a 3 on the offroad scale.
It might do a bit over 3 but at that point you'll have to decide if
resale value matters to you.
 
nice! I just did my first fill after changing my AFE bias. Filled at just under 50 DTE, still had about 7-8 gallons in the tank. So I think using 0 DTE as my fill time is doable, if my OCD mind will allow it
I’ll update my post as it’s been much longer now. I’ve since had a tune and I’ve readjusted the bias. Now the DTE is reading much more accurate, and it’s much closer to marching what the remaining fuel when I fill up. It’s been nice to see it learn and level out properly. So I never have gone down to 0 DTE. I fill up once I have less than 100 miles to empty, and that seems to be pretty accurate now

Ok, so today was the first time I filled my new S&B 60 gal. tank after installing it last week. 🤪👍

My stock filler neck has been modified when the flatbed went on so I can no longer fill by S&B tank at full speed with the big truck pumps, but I swear when I had the S&B tank and my normal stock truckbed I could.. and I did install that one way flow valve too.

Yes, install was a breeze.

I can only fill mine at the first click on the big truck pumps
 
I filled up one time at one of those fast flow big rig setups this summer. I had no issue. I didn't realize there could be an issue. The nozzle went in and it started. It was harder to answer all the stupid questions it kept asking me on the pump screen than it was to actually fill
 
When I install my S&B tank, I plan to not put the check valve in. That should help a fair bit.
 
👍🏼I'll now be taking check valve out
 
You could absolutely be right... Maybe just the optimist in me thinks that I was able to back then.
On mine - OEM and now S&B - big truck pumps - 1st click - anything more and it shuts off.

Did you have the check valve installed?

I have the S&B, I never go to truck stops for fuel, as they are always exponentially more expensive.
