EFI Fuel Tank GM 64-67 Chevelle/Malibu

The EFI Fuel Tank GM 64-67 Chevelle/Malibu by HOLLEY is purpose-built for classic muscle car restorations and modern EFI conversions on second-generation A-body platforms. If you're retrofitting fuel injection into a vintage Chevelle or Malibu, this tank eliminates the guesswork of adapting older mechanical fuel systems to contemporary electronic fuel management. Designed specifically for 1964–1967 GM A-body dimensions and mounting points, it bridges the gap between period-correct aesthetics and 21st-century drivability.

This tank features internal baffling and sumps engineered to work seamlessly with EFI pump assemblies, maintaining consistent fuel delivery under acceleration, braking, and cornering loads that would starve a traditional gravity-feed system. The 32 × 9.5 × 44.25-inch envelope is optimized to fit the original fuel tank location without frame modifications or intrusive interior rework, preserving the car's structural integrity and original appearance. HOLLEY's reputation for precision fuel system components means internal passages, inlet and outlet ports, and baffles are CNC-machined to OEM tolerances, ensuring reliable pressure regulation and preventing vapor lock—critical when pushing horsepower or running the car in summer heat.

Restoration shops, weekend warriors, and serious Chevelle/Malibu builders benefit most from this tank when pairing it with HOLLEY EFI kits or standalone ECU setups. Installation is straightforward for anyone comfortable with fuel system work; the tank drops into the original location using existing strap mounts and clearance points. Whether you're converting a 283, 327, or big-block 396 to EFI for better throttle response, cooler running temperatures, and fuel economy, this tank provides the foundation for a modern fuel delivery system without sacrificing the classic lines of your A-body.
