3x Your Tank Size

S&B's 40 gallon fuel tank directly replaces the OEM 13 gallon tank without any special modifications. This makes for a trouble-free, faster installation process. 



FIX THE FLOW

OEM OBS Tanks are hard to fill. They have a vent inside the filler which makes the fuel opening small.

S&B includes a new filler neck & vent. You can even fill on the low setting at high flow semi stations.

A BETTER, STRONGER BUILD

Your 30-year-old stock metal tank is a ticking time bomb that's prone to rust, external corrosion, and internal delamination that sheds debris, clogging lines and destroying expensive fuel injectors. Upgrading to an S&B high-capacity poly tank not only drastically increases your driving range, but it also permanently eliminates these risks because it's completely immune to rust, prevents fuel-contaminating condensation, and absorbs heavy impacts without cracking.

PERFECT FIT + FINISH

To get more fuel, we designed the tank to go further down. We include a brand new sending unit to fix your faulty sending unit & not have to extend one to fit the bigger tank.
