Installed a 46gallon aux tank in truck bed from link below. I installed myself and was very easy to do. Also added the fuel gauge. Initially plumbed it in with a solenoid valve, fuel pump and external filter, plus a bypass valve around the solenoid and fuel pump in case either failed. Lots of fittings and short pieces of fuel hose. Constant battel against small fuel drips. Removed everything except fuel filter and now rely on gravity feed which works fine. Only takes up 12" of bed space and fits under the stationary panel of my Bakflip cover. Worth every penny.
