1959-1960 Chevy Impala EFI Fuel Tank Kit for LS and LT Engines
When fitting an LS or LT powerplant into a 1959 to 1960 Chevy Impala, this EFI fuel tank kit with its 400 LPH pump addresses the risk of fuel starvation under demanding acceleration. Designed for the B Body undercarriage, it combines pump, sending unit and vent filter in a unified module that mounts to factory points without frame cutting or trimming. Installation time is cut thanks to custom straps and sealing gaskets that lock the tank in place while preserving underbody geometry. All components are made in the USA from corrosion resistant steel and hardware, supporting supercharged or over 550 hp applications with steady pressure through extended runs.
Precision Fuel Delivery with 400 LPH Pump
The heart of this kit is a 400 LPH Walbro pump engineered to sustain consistent pressure for LS and LT powerplants even when pushed beyond 550 hp. By delivering a stable flow rate under rapid throttle changes, the system virtually eliminates fuel starvation during hard launches or extended high speed driving. Its in-tank placement greatly reduces heat soak, preserving fuel quality and lowering the risk of vapor lock when ambient temperatures rise. This level of capacity ensures the engine receives the volume it demands whether cruising on the street or hitting the track.
Integrated in-tank Module Reducing Complexity
Combining the pump, sending unit, and vent filter into one assembly streamlines both plumbing and electrical connections in your Impala swap project. The unified design cuts the number of hoses and wiring harness branches, which reduces potential leak points and installation errors. Technicians benefit from plug-and-play connectors and preset hose fittings that guide installation and save valuable labor hours. At the same time, precise module alignment maintains accurate fuel level readings and consistent venting during rapid changes in load or altitude.
Custom Mounting Designed for 1959 to 1960 Impala
Every strap and sealing gasket in this kit is tailored to match the factory mounting feet on 1959-1960 Chevy Impala B bodies, including Bel Air, Biscayne and Del Ray variants. This exact fit eliminates the need for any drilling, trimming or frame modifications, preserving the original underbody geometry. Once installed, the tank remains secure under harsh cornering forces and uneven road surfaces, thanks to robust hardware and precise bracket placement. The result is a restoration-quality installation that maintains the vehicle's classic stance and structural integrity.
Corrosion Resistant Construction for Lasting Performance
All components are proudly made in the USA from corrosion resistant steel, durable gaskets and premium mounting hardware to withstand exposure to modern fuels and road contaminants. Each element undergoes strict quality control to ensure resistance to rust and chemical degradation over years of use. This material selection delivers confidence in demanding environments, whether the car sees daily driving or takes to the drag strip. The long service life of the tank and its hardware means fewer maintenance intervals and more time enjoying the ride.
