The S&B Tanks 10-1011 is a direct-replacement 60-gallon high-capacity mid-ship polymer fuel tank engineered for 1999–2007 Ford F-250 and F-350 Super Duty Long Bed Crew Cab diesel trucks. Manufactured from premium, high-density cross-linked polyethylene (XLPE), this tank replaces the small factory 38-gallon tank to dramatically expand onboard fuel capacity without sacrificing ground clearance or occupying precious bed space. S&B integrates an advanced internal baffle and anti-wave sump system designed to keep fuel pooled securely around the pickup foot even when fuel levels are critically low during aggressive braking, hill climbs, or hard cornering. The design accommodates the OEM sending unit, float arm, and factory fuel line routing for a seamless, bolt-on upgrade.

Constant fuel stops while pulling heavy fifth wheels or commercial trailers, severe range anxiety when hauling through remote corridors, dangerous fuel starvation caused by fuel sloshing away from the pickup module on steep mountain grades, and rusting or internally delaminating OEM steel fuel tanks peeling protective coatings into the fuel system are what this 60-gallon tank eliminates. The heavy fuel consumption of a 7.3L or 6.0L Powerstroke under load drains standard 38-gallon tanks in just a few hundred miles, forcing drivers to detour frequently for commercial pumps. S&B's seamless XLPE construction is completely impervious to internal corrosion, condensation rust, and modern fuel additives, pushing driving range well beyond 800 miles per fill. It is a direct-replacement mid-ship fuel tank and heavy-duty mounting strap kit only; the factory fuel sending unit is reused, and auxiliary fuel pumps, sump kits, or transfer equipment are sold separately.

It fits 1999–2007 Ford F-250 and F-350 Super Duty Crew Cab models equipped with an 8-foot Long Bed and the 7.3L or 6.0L Powerstroke diesel engine (does not fit Short Bed, Regular Cab, SuperCab, or Cab & Chassis frame configurations).

Run the fuel tank down as close to empty as possible before beginning installation, park the truck on a solid level surface, and disconnect both negative battery cables. Support the factory fuel tank with a transmission jack or wide-cradle floor jack, loosen the fill neck and vent hose clamps, disconnect the sending unit electrical harness, and release the quick-disconnect fuel supply and return lines using appropriate fuel line disconnect tools. Lower the OEM tank from the chassis frame, remove the factory lock ring, and carefully lift out the fuel sending unit assembly—inspecting the plastic intake foot ("duckbill") for cracks or deterioration and cleaning out any residual debris. Install the supplied S&B float arm extension onto the factory sending unit arm to ensure the in-cab fuel gauge reads full and empty sweeps accurately across the deeper 60-gallon tank floor. Lower the modified sending unit into the S&B tank with a fresh Viton O-ring gasket, secure it using the provided heavy-duty locking ring, and raise the tank into the chassis frame pocket. Fasten the tank securely using the included S&B heavy-duty mounting straps, reconnect all fuel hoses, vent tubes, and electrical plugs, and add clean diesel fuel to verify seals prior to vehicle operation.
