2010 GMC 2500HD - 26 gallons. I swapped it out for an aftermarket tank that holds 45 gallons.

2011 they switched to 36 gallon tank for 25/3500.

2010 was 26 gallon for standard bed and 34 gallon for long bed.

2011 was also all the new chassis/frame/brakes/front axle and LML with DEF.

1500 series are different and chassis cab is different

so no options to upgrade the 2016 1500 trucks?

23 gallons in my 08 Duramax standard bed. Or maybe it is 26 when I've used 21 gallons, it says I have maybe 50 miles left to empty. My former 08 Duramax and 2012 Duramax long bed had a 32 gallon tank.

2016 manual only shows 98L / 26 gallon for 1500's.

Aftermarket doesn't seem to do gasoline tanks.

Difference in frames, so HD tanks aren't going do be direct bolt in.

2016 OM:

Fuel Tank
1500 Series 98.4 L 26.0 gal

2500 Series and 3500 Series Standard Box 136.3 L 36.0 gal
3500 Series Long Box 136.3 L 36.0 gal

Going custom is the only way.

I suppose anyone could rig up a nice plastic/metal tank under the truck, have a mini pump on a switch that fills the main tank with a feed line into the fuel filler neck. Then vent the small aux tank into the filler neck as well.

Might throw the question around over at duramaxforum.com as well, I recall a few people over there had done some upgrades for fuel tanks before I stopped going to that site due to how shitty of a layout it is now.
