EFI Fuel Tank Sys. Steel 78-81 Camaro 255LPH

The Holley EFI Fuel Tank System for 1978–1981 Camaro with 255 LPH electric fuel pump is a complete fuel system upgrade designed for modern EFI conversion on classic F-Body platforms. This 21-gallon steel fuel tank kit addresses one of the most critical infrastructure needs when transitioning a carbureted engine to electronic fuel injection: a fuel delivery system engineered to support consistent pump pressure and flow under varying operating conditions.

The system delivers 255 liters per hour of fuel flow capacity, sufficient to support forced-induction and naturally aspirated engine builds that demand reliable, pressure-stable fuel delivery. The tank features 1/4-inch NPT outlet and return ports, a configuration that integrates directly with industry-standard EFI fuel lines and regulators. Construction is steel with a durable silver powder-coat finish, providing corrosion resistance and aesthetic authenticity while maintaining the structural integrity required for fuel containment. An integrated sending unit enables accurate fuel gauge functionality on your dash display, eliminating the need for aftermarket gauge integration.

This kit is purpose-built for Camaro owners undertaking modern EFI conversions who need bolt-in fuel system compatibility. Second-generation F-Body platforms—particularly when upgraded with contemporary engine management systems—benefit from a tank designed with EFI supply and return routing already engineered into the design. The 255 LPH capacity provides margin for fuel rail pressure spikes and ensures the pump operates within its efficiency envelope rather than at maximum output during sustained driving, extending pump longevity.
