Fuel Cell Wedged 18 Gal Black

The Fuel Cell Wedged 18 Gal Black from RCI is purpose-built for serious motorsports and high-performance vehicle applications where fuel capacity and weight distribution demand precision engineering. Whether you're running circle track, drag racing, road course competition, or building a restomod with modern performance requirements, this 18-gallon fuel cell replaces traditional tanks with a robust, safety-engineered alternative. Designed for drivers and builders who refuse to compromise on reliability or performance, the RCI fuel cell delivers the capacity you need without sacrificing vehicle balance or adding unnecessary weight to critical chassis areas.

RCI's wedge design optimizes interior space and allows flexible mounting in tight engine bays, vehicle rear sections, or custom installations where a conventional rectangular tank won't fit. The cell features a welded steel or composite construction built to withstand vibration, impact, and the demands of competition environments while maintaining structural integrity. At 46.7 lbs and measuring 25.7 x 19.2 x 27.2 inches, the Fuel Cell Wedged 18 Gal Black strikes a balance between adequate fuel volume and reasonable weight—critical factors when tuning your vehicle's weight distribution, handling characteristics, or compliance with racing class regulations.

Mechanics and performance builders working on vintage muscle cars, modern track cars, or dedicated race vehicles will appreciate the wedge profile, which adapts to unconventional mounting locations and works within tight packaging constraints. Installation requires careful attention to fuel line routing, vent lines, filler neck positioning, and electrical ground points—tasks best performed by experienced technicians familiar with fuel system safety protocols. The black finish resists corrosion and blends seamlessly into most engine bay or trunk environments, making this RCI fuel cell ideal for both functional race cars and street machines where aesthetics matter as much as performance.
