Description
The Cleveland Tank RS1540CC-51 is a 40-gallon rectangular steel diesel fuel tank engineered as a direct-fit aftermarket replacement, cross-referenced to IC Bus OEM part numbers 6123653C93. If your factory fuel tank is leaking, rusted, or malfunctioning, the RS1540CC-51 mounts between the frame rails and restores your bus or truck to full service without cutting, drilling, or fabrication. It’s built from heavy-duty mild-grade steel with an internal rust-preventive coating and a gloss black powder coat exterior finish, engineered to the same quality standards and specifications as the original OE tank, and every unit is pressure tested to confirm leak-free performance before it ships. Always confirm exact fitment against your chassis VIN or existing OE tank part number before ordering, as capacity and mounting configuration can vary by model year and build.
The RS1540CC-51 measures 28.75 inches long by 25.00 inches wide by 15.50 inches high and weighs 110 lbs. It mounts between the frame rails, holds 40 gallons of diesel fuel, and carries full DOT approval. Every tank 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. It pairs with a stainless steel mounting strap (SS5980TT200-00), bracket insulator (RIF1.50), and strap insulator (RI2.00-01) for installation. A sending unit, sight gauge, locking fuel cap, and drain check valve are available as optional add-ons at the time of order.
Like the rest of Cleveland Tank’s rectangular steel lineup, the RS1540CC-51 pairs mild-grade steel construction with an internal rust-preventive coating and gloss black powder coat exterior to guard against the corrosion that typically ends an OE tank’s service life, while keeping cost down for a mid-capacity, frame-rail-mounted application. Every tank is pressure tested and DOT-approved for diesel fuel use before it leaves the factory.
