S&B Tanks

About S&B Tanks

S&B Tanks is the fuel storage division of S&B Filters, a family-owned American manufacturer headquartered in Fontana, California. S&B Filters was originally founded by Sal and Barbara — the names behind the “S&B” brand — and has grown over decades into one of the most respected names in the diesel truck aftermarket. The company has been family-owned since 2003 and maintains in-house control over much of its manufacturing process, ensuring consistent quality and exceptional value for working truck owners and performance enthusiasts alike.

What S&B Tanks Makes

S&B Tanks specializes in high-capacity replacement fuel tanks engineered for diesel trucks and commercial vans. If you’ve ever been frustrated by the limited range of a stock factory fuel tank on a hard-working diesel, S&B Tanks was built to solve exactly that problem. Their tanks are direct replacements for the OEM fuel tank, designed to mount in the stock location without requiring any cutting, drilling, or modification to nearby components.

The lineup covers the most popular diesel platforms on the road, including Ford Power Stroke, Chevrolet/GMC Duramax, and Dodge/Ram Cummins trucks, as well as Mercedes Sprinter vans. Capacity upgrades are substantial — replacing a factory 31-gallon tank with a 52-gallon S&B unit, or swapping a stock 36-gallon tank for a 62-gallon midship tank, means significantly fewer fuel stops and more time getting work done.

Engineering & Build Quality

Every S&B replacement fuel tank is built from high-density crosslink polyethylene and ships as a complete kit with all hardware needed for installation. Mounting straps are E-coated stainless steel for extreme corrosion resistance, and the tanks are designed to reuse the factory fill neck and sending unit, keeping the installation straightforward and the dash gauges accurate. Internal anti-wave baffles help manage fuel slosh under hard acceleration and braking, and all tanks are compatible with fifth-wheel and gooseneck hitches — a critical detail for truck owners who tow.

Beyond fuel tanks, the S&B Tanks lineup also includes water tanks for van conversions and overlanding builds, fuel transfer kits, fuel sending units, auxiliary fuel components, and sump kits — making it a comprehensive resource for anyone building out a diesel truck or van for long-range work or adventure.

Why S&B Tanks?

S&B has built its reputation on engineering innovative, dependable products while keeping manufacturing in-house. The same philosophy that drives their performance air filter and cold air intake products — thorough testing, real-world validation, and a commitment to out-performing the competition — applies directly to their tank lineup. Whether you’re a fleet operator looking to extend service range, a diesel enthusiast chasing maximum miles per tank, or a van-lifer building a mobile home, S&B Tanks delivers a direct-fit, high-quality solution backed by a brand with decades of aftermarket credibility.
