High Flow LS LT EFI Fuel Tank for 1961-1964 Impala

Achieve dependable fuel delivery for supercharged or 550+ horsepower LS or LT setups in your 1961 to 1964 B Body Impala with this tailor made EFI tank and 400 LPH Walbro pump engineered for precise fit and real time level monitoring. Every kit comes complete with straps, filters, gaskets and hardware for a plug and play install that prevents fuel starvation under high demand.

1961-1964 Chevy Impala B-Body LS and LT EFI Fuel Tank Kit

Swapping a modern LS or LT engine into a 1961 to 1964 Impala B Body often exposes limitations in the original fuel system. Equipped with a 400 LPH pump, this Impala EFI Fuel Tank Kit delivers steady flow to support engines producing over 550 horsepower. Installation uses the factory mounting points and the supplied straps, vent filter, gaskets and hardware for a drop in fit. The integrated sending unit tracks fuel levels in real time to help prevent starvation during spirited driving.

High Capacity Fuel Pump Supporting Over 550 Horsepower

The heart of this fuel tank kit is the 400 LPH Walbro module, engineered to maintain steady flow for supercharged and high-output LS or LT powerplants. By delivering a consistent supply at elevated engine speeds, the pump prevents fuel starvation during sustained wide-open throttle and aggressive driving. Its in-tank placement also reduces heat soak, preserving fuel coolness and density for optimal combustion. This reliability under load makes it a trusted choice for builds that exceed 550 horsepower.

Tailor Made Fit for 1961 to 1964 Impala B Body

Designed specifically for 1961 through 1964 Bel Air, Biscayne, Del Ray and Impala B Body frames, this tank drops into the factory well with no metal modification required. The mounting flanges and filler neck align perfectly with the original chassis points, preserving the car's structural integrity and ground clearance. By matching OE dimensions, the tank maintains the factory appearance under the trunk floor and ensures proper tank-to-frame clearance. Enthusiasts save time and avoid trimming sheet metal or relocating the fill spout.

Integrated Sending Unit for Real Time Fuel Monitoring

The built-in level sender communicates accurate fuel measurements to your dash gauge, helping prevent unexpected runs on fumes during spirited cornering or hard acceleration. Its float arm is calibrated to the stock impedance, so no dash module reprogramming is required. Wiring harness connectors match GM standards for quick plug and play hookup. This precise monitoring adds confidence on long road trips and track days by alerting you to low fuel well before starvation occurs.

Comprehensive Kit Design for Simplified Installation

Everything needed for a swift upgrade arrives in one box: the fuel pump module, sending unit, heavy-duty tank straps, filler neck, vent filter, gaskets and mounting hardware. Each component is specified to work together, eliminating the hassle of sourcing parts separately or adapting mismatched fittings. Bolts, seals and hoses are pre-measured for a direct fit, reducing installation time to just a few hours with basic tools. This complete solution streamlines the conversion process and gets your classic Impala back on the road faster.

Engineered for precise fit and reliable operation. To match a smaller capacity fuel pump Kit at 255 LPH consider our 1961-1964 Impala EFI Fuel Tank Kit - 255 LPH Pump.
