Larger Fuel Tank for Burb/YXL (gas)?

[Dewally]

Does anyone offer a solution for a larger fuel tank for the Suburbans/YXL for 2015 - 2020? I was hoping to increase my tank size to at least 45 gallons.

I have done an extensive search and it appears there is plenty of support for the Trucks, but nothing for Suburbans.

No, the government consider the fuel tank part of the emissions system so the aftermarket won't touch it anymore. The 2500s have a second tank with pump above the spare but we don't have the clearance to adopt it. There is or was a tank made that hung in place of the spare tire. 3 Wavian Jerry Cans will more simply meet your needs and not stink up the cab as they don't leak.
