..... or u could just buy a fuel cell...im suprised no one has mentioned that, they really arent that expensive and the look about 12 times better then a messy fucked up lookin stock tank. you can build it if you want also to any demension u want , if your investing thousands into your truck for all this work im sure an extra $250 wont hurt to order your self a custom tank, w/ custom demensions from
www.aluminumfuelcell.com and you can even mount it inthe stock location if your feeling a little froggy
