Top Off Without Leaving the Driver's Seat — Gravity Feed for 2013-2022 RAM
Built for RAM 2500 and 3500 diesel owners running an in-bed transfer tank, this Southern Truck install kit ties your auxiliary tank straight into the factory fuel filler neck. No pump, no wiring, no drilling — open the valve and let gravity do the work.
Key Value Highlight
The whole game here is fill-neck fit. This kit uses a 1.75-inch outer diameter aluminum tee sized for the 2013-2022 RAM 2500/3500 filler neck, so the connection seals clean the first time instead of leaving you chasing leaks in the driveway. Every hose, clamp and fitting you need is in the box, and most installs wrap inside an hour. Once it is in, your range roughly doubles and fuel stops stop dictating your schedule.
