Let's face it, the factory 31-gallon fuel tank that comes factory on your 5.9L or 6.7L Cummins just does not cut it. This 55-gallon direct replacement tank will allow you to keep going down the road while others are stuck looking for fuel stations. S&B has thought of everything while developing this tank. They not only have almost doubled the fuel capacity but have done this all while maintaining maximum ground clearance and hassle-free installation.
PLUG-AND-PLAY INSTALLATION
The S&B Tank comes with all the components to remove your 31-gallon tank and replace it with the 55-gallon tank. The tank mounts in the stock location using the included straps. The tank occupies the space forward of the OEM fuel tank.
FUEL GAUGE FUNCTIONALITY
Even with more fuel on board, your fuel gauge will remain working. The gauge will stay on full for the first 7-10 gallons, but then continue to move as normal. The distance to empty however will still be calculated based on the stock fuel capacity. For example, @ 20mpg and a full tank (55 gallons), you will have an 1100 range but your distance to empty will show 620 (20 MPG * 31 gallons).
