S&B 60 gal tank

You can do it with FORScan.
Kinda, but not really...
Cool, how?
The 23+ do not have a fix like the 22 and older trucks. I have seen where people can change to the larger OEM size in FORSCAN but not the actual tank size that transferflow or S&B use. The larger OEM size gets it closer, but still not spot on like in the older trucks.

Yup, this is correct.

 
On the 23+, Correct on the not 100% on the DTE with ForScan
Make the change in PCM plain English
Testing is showing once the change is made there is about a 50% increase in capacity. Then as you drive the DTE doesn’t drop as you would think it should and by the end of the tank the mileage is more inline with what the DTE should read.
I am hopeful I can find the code with more people testing.

Got the bad boy installed today. That initial fill up was painful. But sure will be nice not having to fill up every week. Are the old tanks pretty much worthless? My truck only has 1k miles on it. I hate to throw it out but I can't hold onto it with no storage space.

I hope to install on on my ‘24 soon, but when I did it on my ‘21 I just wrapped it up in a tarp a tossed behind my shed. When I moved from that house I tossed it, so good to keep in an emergency but most likely will never touch it again.

Pretty much useless. I have a friend that uses is to hold additional fuel for his little standby diesel generator.
 
Tossed my OEM tank within a few hours of finishing the install job.
 
Just thought y'all would like to see roughly how much fuel is above the float. Just filled up with the fam and it's 98* here today according to the CTS so I left the truck running. Prior to filling, the cluster fuel gauge was roughly an 1/8 or 7% on the CTS.

I had 50mi DTE pulling into the station off the hwy... The CTS fuel % showed 100% fuel at 43 gallons pumped and I ended up pumping out to 57 gallons. So give or take slight fuel tank casting anomalies there's roughly 17 gallons above the float lol
 
Was able to get mine Installed today by a buddy at his brothers down the road. They are gear heads and love working on shit. offered some cash if he had the time.

Put 57.8 gallons total in. I didn’t have him install the backflow valve, and ended up with so much foam, it flowed out. Due to it being too hot to stand around outside that is where I left it.

I left my valve out at first as well, but had some similar issues and pumps not clicking off, so I installed it. Didn’t have to drop the tank, just disconnect filler hose and place it in there.

I remember reading about it, and that the big boy nozzles won’t flow because of it
 
I have the check valve installed for the safety of it in case of a rollover and the filler hose was to come disconnected.

When using truck stops to fill up I do have to keep the nozzle on the first stop. Any further and it shuts off. It’s usually on road trips with the TT, so a couple more minutes standing is ok with me.
 
Forgot to add that I am very happy with more fuel onboard. On a full tank we pulled the TT from Rock Springs, WY up to Jackson, then up to West Yellowstone. After setting up camp we spent days exploring Yellowstone (hours and hours of 45 mph driving) and I’m just now showing down to 1/2 a tank.

I will never forget the first time I filled up and it showed 951 mile range - so nice to have the added range for towing, knowing I can go close to 600 miles with the toybox in tow! My favorite mod for sure.
