Cleveland Tank & Supply has added a new steel diesel fuel tank to its lineup: the RS16100CC-52, a 100-gallon direct-fit aftermarket replacement engineered for school bus fleets running Thomas Built Buses chassis. The tank is cross-referenced to Thomas Built Buses OEM part number 164675, so fleet maintenance teams can order the exact replacement tank their bus needs instead of guessing at fitment or paying for custom fabrication.
If a factory fuel tank is leaking, rusted, or otherwise failing, a direct-fit replacement tank mounts between the frame rails using the same footprint as the original equipment tank, with no cutting, drilling, or welding required. That matters most for school bus operators, where a tank failure means a bus sitting out of service instead of running its route. The RS16100CC-52 is pressure tested for leak-free performance before it ships and carries full DOT-approved fuel tank certification for diesel fuel use.
RS16100CC-52 — 100-Gallon Steel Fuel Tank for Thomas Built Buses
The RS16100CC-52 is a 100-gallon rectangular steel diesel fuel tank cross-referenced to Thomas Built Buses OEM part number 164675. It measures 66″ L × 24″ W × 16″ H, weighs 195 lbs. and mounts between the frame rails.
Built for Corrosion Resistance and Long Service Life
The RS16100CC-52 is built from heavy-duty mild-grade steel with an internal rust-preventive coating and a gloss black powder coat exterior finish, the same corrosion-resistant approach used across Cleveland Tank’s rectangular steel tank lineup. It ships ready to install with a magnetic drain plug, rollover protection vent, vent tubing, fuel cap, drawtube, return fitting, equalizer fitting and sending unit flange. A sending unit, sight gauge, locking fuel cap and drain check valve are available as optional add-ons at checkout.
Installation is straightforward with the right hardware. Cleveland Tank’s mounting straps, brackets and rubber insulators are sized to match this tank, including the mounting strap S5800TT200-00, bracket insulator RIF1.50 and strap insulator RI2.00-01.
Confirm Fitment Before Ordering
Capacity and mounting configuration for Thomas Built Buses fuel tanks can vary by model year and build, even within the same chassis family. Before ordering the RS16100CC-52, confirm exact fitment against your chassis VIN or your existing OE tank part number. If you’re not sure this tank matches your bus, contact Cleveland Tank’s team for help cross-referencing your part number.
