Hey Stirling, I have a solution for you but the part # UWS39XR is a transfer tank and not an aux fuel tank like the part # DZ91753X that also fits your 2012 Chevy Silverado 3500. This does come with ability to gravity feed into your fuel tank and act as an additional fuel tank. Would this work for your needs?
