It cannot, but you can use a Titan 55 gallon tank.

I am hearing that the actual truck frame is different between the 32 gallon and 50 gallon trucks, also s&b or titan

I think it's the crossmembers that are different, as well as DEF tank plumbing routing.

I ran the Titan in my '18 and really liked it. The install was very easy.

Plus 1 for Titan.

Can you still use the fuel gauge? is it still accurate, same for the computer values ?

Gauge reads pretty linear after the first 10 gallons burned, it doesn’t move at all for the first 10 gallons.

DTE is way off and there is no way to make the tank bigger in the ECM.

DTE can be corrected using AlfaOBD and adjusting the tank size to 197 liters. Works great, and I'm loving my Titan.

Not on the 4.0 Gen trucks, which is what I had a Titan in, and the Gen in Bootsy’s avatar…. And the Gen for this section.
