61-64 Impala B-Body EFI Tank for LS LT Builds

Optimized for 1961 to 1964 Impala B-Body applications, this EFI tank kit delivers precise fit and reliable fuel flow for LS and LT powerplants thanks to its 400 LPH Walbro pump and integrated sending unit that prevents starvation in high-demand runs. Complete with straps, filters, gaskets and all mounting hardware, the comprehensive kit ensures swift installation and consistent performance under supercharged or over 550 plus horsepower conditions.

1961-1964 Chevy Impala EFI Fuel Tank Kit for LS and LT Swaps

When tackling an LS or LT engine swap in a 1961 to 1964 Impala B Body the original fuel tank's capacity and flow limitations become obvious. This 1961 to 1964 Impala EFI Fuel Tank Kit features a 400 LPH Walbro pump rated to support powerplants making over 550 horsepower without fuel starvation under sustained high load. It drops directly into the factory well with supplied straps gaskets and vent filter so no chassis modifications are needed. The integrated sending unit sends accurate fuel level readings in real time helping you avoid empty runs during spirited driving.

Precision Fit for Classic Impala Chassis

This fuel tank kit is engineered to match the exact dimensions of 1961 through 1964 Impala, Bel Air, Biscayne, and Del Ray B bodies, allowing it to seat perfectly in the factory well without altering sheet metal or frame rails. Mounting flanges and filler neck align with the original points to preserve ground clearance and trunk floor appearance. By maintaining OE spacing to the rear suspension and exhaust, the design safeguards against rattles and rubbing under spirited driving. Installation retains the vehicle’s structural integrity and keeps the factory fill spout location intact.

Consistent Fuel Supply for High Output Engines

At the heart of this kit is a 400 LPH Walbro pump calibrated to sustain supercharged or 550+ horsepower LS and LT powerplants under demanding conditions. In-tank placement minimizes heat soak, preserving cool fuel density for efficient combustion during extended wide open throttle runs. Steady pressure delivery prevents fuel starvation when cornering or accelerating hard, ensuring the engine receives the precise mixture it needs. This reliability makes it ideal for enthusiasts pushing their setups beyond stock output levels.

Integrated Fuel Level Sensing for Driver Assurance

The built-in sending unit delivers real time readings to your factory gauge cluster, helping you avoid surprise low-fuel situations on long runs or track laps. Its float arm and impedance match stock specifications so no gauge recalibration is required. GM style wiring connectors snap into the existing harness for a seamless plug and play hookup. Accurate monitoring gives drivers peace of mind, whether cruising highway miles or tackling back road runs.

All Inclusive EFI Tank Kit for Easy Installation

Every component needed for a clean swap arrives ready to install, including the pump module, sending unit, heavy duty straps, filler neck, vent filter, gaskets, and mounting hardware. Pre-measured bolts and seals eliminate the guesswork of sourcing compatible parts and ensure fast assembly with basic hand tools. By bundling these elements into one package, the kit cuts install time to just a few hours and eliminates trips to the parts counter. This complete solution lets you focus on wiring and tuning rather than hunting down fittings.

Complete your fueling solution with consistent pressure and consider our 1961-1964 Impala EFI Fuel Tank Kit - 255 LPH Pump for a Smaller capacity fuel pump Kit at 255 LPH.
