F250 Short Bed Adding Diesel Auxiliary Tank

I have a Ram 2500 CTD crewcab short bed. I put in a Better Built transfer tank that I bought on Amazon from Northern Tool. I bought there because I wanted a black one. You can get a white one from Tractor Supply. It is 36 gallons and is 42 1/4 wide x 17" high x 11" deep. I use a 6' siphon hose 3/4 ID. It works great . You don't need a transfer pump. It takes little room and fits under my cover. I have it secured with 2 heavy duty ratchet straps, holds it great. That way I can take it out if I need the room to carry anything.
