1961-1964 Impala B-Body LS EFI Fuel Tank Setup

Achieve unwavering fuel pressure at every throttle input thanks to the efficient 255 LPH Walbro pump and precision steel tank engineered for LS swaps in 1961 to 1964 B Body Impalas. Complete with a dedicated wiring harness and mounting hardware, this fuel tank kit supports engines up to 550 horsepower, delivering sharper acceleration, improved fuel economy, and consistent fuel delivery under demanding conditions backed by American craftsmanship.

1961-1964 Chevy Impala LS EFI Fuel Tank Kit with 255 LPH Pump

Upgrading a 1961 to 1964 Impala B Body to LS power demands a reliable fuel system and this 255 LPH pump and steel tank assembly delivers just that. The design retains original mount locations and filler neck alignment so it installs without any modification to your chassis. Beyond fitment precision the in tank pump module suppresses noise and draws heat away from its motor for a longer service life. Builders tackling modern LS EFI projects will value the consistent pressure and plug and play simplicity of this solution. Each kit is built in the United States for reliable operation under varied driving conditions.

Precision Integration with Classic Impala Frame

This steel fuel tank assembly is tailored to align precisely with the frame rails and strap bosses of 1961 to 1964 Chevy Impala B Body chassis. Constructed from heavy gauge steel, it preserves the factory filler neck location and mounting bolt pattern so no frame modification is required. By maintaining original ground clearance and body proportions, vehicles retain their authentic stance while benefiting from modern fuel delivery. Technicians save time with a true drop in design that eliminates guesswork and custom fitting. This exacting fitout ensures the upgraded system remains invisible to the eye yet fully compatible with vintage sheet metal.

Immersion Cooling and Quiet Fuel Pump Operation

The 255 LPH Walbro pump is mounted inside the tank where it is fully bathed in fuel, drawing heat away from its motor to prolong service intervals. Submerging the unit also isolates vibration and flow noise for a quiet cabin environment even under load. Combining the pump, sending unit and filter into one module eliminates extra plumbing and reduces the risk of leaks. This integrated approach ensures constant fuel pressure and virtually eliminates vapor lock when the engine is under high stress. Cumulative noise reduction and thermal management translate to a more refined driving experience without sacrificing performance.

Consistent Flow for Up to 550 Horsepower LS Engines

Delivering 255 liters per hour, the fuel pump module easily supports LS swaps producing up to 550 horsepower without strain. This ample flow rate sustains a stable fuel to air ratio from idle through full throttle, preventing lean spots that can damage engine internals. Riders will feel immediate throttle response and unwavering power delivery during hard acceleration or sustained high speed cruising. The system design aligns with modern EFI requirements and accommodates a wide range of tuning setups. Whether for street performance or competition driving, this kit provides the margin needed for safe high output operation.

Complete Kit for Streamlined EFI Conversion

This all inclusive assembly ships with every component required to install a modern LS injection fuel system on 1961 through 1964 B Body applications. In addition to the pump module and sending unit, the package contains tank straps, filler neck, vent filter, gaskets and all mounting hardware. By consolidating these parts in one box, installers avoid compatibility issues and reduce downtime sourcing separate pieces. The pre assembled tank simply bolts into existing chassis mounts before connecting to original fuel lines and electrical circuits. Builders can focus on calibration and performance tuning instead of part selection and logistics.

Count on this assembly for reliable pressure and seamless installation in your LS conversion. For a larger capacity fuel pump Kit at 400 LPH see our 1961-1964 Impala EFI Fuel Tank Kit - 400 LPH Pump.
