Installed a ATI (Aluminum Tank Industries -
http://atitank.com/)in our 2011 Ram 3500 Dually 4WD, in 2011. Gravity flow, 41 gallon tank. Love it!!!
Installation was very simple and easy. When both tanks are full and you start your journey and the fuel gage starts to move you know you have gone through Aux tank. That simple. Only thing you need to remember is when Aux is full and feeding main tank - DO NOT OPEN ORGINAL FUEL CAP!!!
Found out hard way - just was not thinking. Ours came with cut off and Gage.
Hybrid Mode
