Significantly increase the range on 2013-2026 Ram Cummins 6.7L Crew Cab Long Bed trucks by upgrading to the S&B 56 Gallon High-Capacity Fuel Tank — a direct, bolt-on replacement for the stock 31 gallon tank.

Important Notes:

• The fuel gauge will continue to work however the distance to empty will not be accurate. There is no way to update the fuel tank size for the distance to empty to be accurate.
•  OEM sending unit & float are reused because the S&B Tank is taller the gauge will stay on full for the first 8-10 gallons

NEARLY DOUBLE THE CAPACITY

The S&B 56 Gallon High-Capacity Fuel Tank is a direct replacement for the 31 gallon factory tank. With 25 more gallons of fuel available, the S&B tank allows you to travel over 1,000 miles between fill ups, whereas the smaller stock tank will only get you about 600 miles. Enjoy the freedom, flexibility and time saved with a significantly bigger tank.

"NO SLOSH" TANK DESIGN

S&B tanks are engineered with built-in baffles to minimize fuel sloshing. This innovative design ensures fuel stays around the pick up and prevents unwanted tank sloshing noise.

STRONGER THAN STOCK

Made with 1/4" thick cross-linked high density polyethylene (XLPE), the S&B tank has significantly more impact strength than the OEM linear polyethylene tank. This is a big advantage when trekking offroad.

HI-FLOW NOZZLE COMPATIBLE

This high-capacity fuel tank works seamlessly with the high-flow fuel pumps found at truck stops and is engineered to handle rapid fueling without premature shut off or causing overflow. With its optimized venting, fill-ups are smooth and hassle-free allowing you to get back on the road quickly.

USE ALL THAT WASTED SPACE

It's shocking how much empty space there is underneath the 2013+ 6.7L Cummins Crew Cab Long Bed. S&B's advanced scanning technology and industry-leading tank manufacturing turns all that wasted space into 25 extra gallons of diesel carrying capacity so you travel further on one tank than you ever thought possible.
