If its 400 burb to 400 Silverado I'm sure its doable but needs to be fabricated not to mention extension of fuel lines and electrical plus filler neck unless you reroute to a new point. I'm surprised you didnt take the saddle tank route so you can still have a spare tire at the rear

I plan to do this to Frank (avatar) but I can't seem to get enough fires put out around here!

My plan is to remove the crossmembers and filler neck from the donor Sub and keep the original tank as well.

You and Frank be sure to keep us posted!

I’m considering doing it for more fuel capacity.

Off the cuff anyone know how many gallons k3500 quad cab tank holds?
