AUX GRAVITY FEED DIESEL TANK 2017 RAM 3500
Just bought a new ram 3500 and am curious if a gravity feed fuel tank can be installed. I plan to move the tank from my 05 ram to the new truck. Will appreciate any feedback.

With all that being said, those that have the tanks, how do you control the flow, do you stop and open a valve then watch gauge then stop and close the valve or is it in the open position all the time??
I have thought about putting a RDS tank in but had also thought I use a normally closed 12v solenoid valve that I could switch open while driving then switch it off when its filled or nearly filled the truck tank...any ideas??
My valve stays open all the time. As long as both fuel caps are on tight, the tank will not overfill.
My 15 doesn't have a fuel tank cap other than the 0-ring one I installed to help keep dirt out. It does sound like after reading other posts that there is a backflow preventer in line.
Yes, it is in the "tee' that gets installed in the factory filler tube down next to the factory tank. When the factory tank fills to the check valve the little ball floats up to stop the incoming flow. Mine has worked great for two trucks now. 2013 and 2016 Rams. I have never had a problem with leaving my valve open. When I need fuel and not towing I just fill my aux tank and go. It fills my factory tank. The only time I put a nozzle in the factory fill tube is when I'm going on a trip and need to fill both tanks. Then I will fill the factory tank first and then the aux tank. My factory tank stays full 90% of the time.
