Fuel Cell Poly 12 Gal w/sender

The Fuel Cell Poly 12 Gal w/sender from RCI is purpose-built for serious performance and racing enthusiasts who demand reliable, lightweight fuel storage without compromising vehicle dynamics. Whether you're upgrading a street rod, track car, or off-road platform, this 12-gallon fuel cell eliminates the safety and weight penalties of factory steel tanks while delivering the consistency needed for sustained high-performance driving. The integrated sender unit ensures accurate fuel level monitoring in the cockpit, eliminating guesswork during long acceleration runs or extended track sessions.

Constructed from durable polyethylene, the fuel cell resists corrosion and vibration-induced failures that plague traditional metal tanks in modified vehicles. The design prioritizes structural integrity under lateral g-forces and longitudinal acceleration, critical for maintaining fuel delivery when suspension geometry changes or vehicle stance is lowered. At 15.35 pounds when empty, the cell significantly reduces unsprung mass compared to steel alternatives, directly improving handling response and reducing brake fade over extended driving sessions. The compact footprint of 18.5 x 14.6 x 18.5 inches enables flexible installation in tight engine bays, trunk spaces, or custom-fabricated mounting locations—essential for kit car builds, engine swaps, and radical weight-reduction projects.

This fuel cell suits vintage muscle car restorations, drag racing platforms, road course competitors, and any enthusiast converting from carburetor to EFI injection systems. The pre-installed sender integrates directly with most aftermarket fuel gauges and engine management systems, eliminating the need for secondary sensor fabrication. Installation requires basic mechanical skills and attention to fuel line routing best practices—always use braided stainless steel hose rated for your fuel type and pressure specification. Verify mounting clearance with your vehicle's suspension and exhaust components before finalizing installation to ensure long-term reliability.
