I know there are products out there that utilize the spare tire area for huge fuel capacity. I especially like the tank that BajaOverland created, but it's out of my budget. I already have the OEM subtank, so I started wondering if there might be a way to split it, add a few inches to its depth, and then weld the bottom right back on. This seems like basic welding shop work to me and you could add probably 8-10 gallons of capacity. I figure that's two jerry cans worth of fuel so it worth investigating. The mounting straps could then just be extended and since you're re-using the bottom half of the tank, the straps would function just like before.
The problem is, I don't really understand how gas tanks work too well. If you increase the capacity, will the transfer pump be able to draw all of the fuel? Will the overhead fuel gauge still be accurate? Other potential problems?
