Aux Fuel Tank 2013 GMC Yukon XL 2500

[Caymanboy]

Anyone heard of an OEM Aux Fuel tank on a 2013 Yukon XL 2500?
Do they come with one?

The 2500 has TWO tanks, one fill. Iy has a small tank above the rear spare. That tank holds about 6 gallons. You should have about 38 gal total.

I'd love to add that tank to my truck. It's too tall to fit up above our spare tire as our frames are shorter.

The second tank is just over 11 gallons and has its own fuel pump and float assembly. It's set up to drain at the same rate as the main tank so no separate gauge is required. The PN# for the tank is the same for both generations, the 800s and 900s. HD Rear Fuel Tank - 23306963

I was thinking about that 6 gallons above the spare.

Yeah I had a 2004 Avalanche 2500 and the aux tank was 11 gallons. It had the 8.1 so it was ALWAYS thirsty but pulled a 31 ft Cat no problem.
