Ok, well that settles the fuel tank decision, I will be using the factory transfer pump which means I will need a cab & chassis tune. If someone could point me in the right direction would be great. Also, does anyone know if this requires changing wiring to the pump? I can compare wiring diagrams for both applications if need be. What about adjustable petals? If I remember correctly from other threads, I will need a petal assy from a 2007 or newer sub, tahoe etc? Can anyone confirm this? I don't have much for progress to report yet, the suburban remains driveable as I am in the process of disassembling the donor. Hopefully I will have some progress to post soon. Thanks to everyone for sharing your knowledge and helping me out!
