EFI Fuel Tank Kit for 1959-1960 Chevy Impala LS and LT Swaps
If you are installing an LS or LT engine into a 1959 to 1960 Chevy Impala B Body this EFI fuel tank kit ensures consistent fuel delivery under demanding throttle applications and long highway runs by leveraging a 400 LPH pump. Inside the in tank module the pump, sending unit and vent filter are combined into a single corrosion resistant steel assembly that bolts to factory frame points without cutting or trimming. Engineered to maintain original underbody geometry this assembly accommodates supercharged or over 550 hp setups while preserving accurate gauge readings and speeding installation with US made hardware and factory aligned fittings.
400 LPH Pump Optimized for LS and LT Engine Applications
The core of this fuel tank kit is a 400 LPH Walbro pump selected for its ability to maintain steady flow under aggressive throttle conditions and extended highway cruising. Positioned inside the tank shell, the pump benefits from the surrounding fuel as a natural coolant, which reduces vapor lock and preserves component life. The high volume output easily supports supercharged engines and powerplants exceeding 550 horsepower without pressure dips during sudden RPM shifts. By keeping fuel pressure and flow consistent, the system safeguards precise air fuel ratios, ensuring smooth acceleration and reliable performance across all driving scenarios.
Integrated Pump, Sending Unit, and Vent Filter Module
By uniting the pump, sending unit, and vent filter into a single in tank module, this design eliminates extra fittings and simplifies the fuel plumbing and wiring layout. Technicians follow factory aligned connectors and preset hose terminations that guide correct installation, reducing the risk of leaks or misrouted lines. Fewer joints also mean fewer potential failure points, which translates to greater system reliability over time. The streamlined assembly process cuts labor hours, helping custom shops and restorers move from chassis prep to road testing with minimal hassle.
Precision Fitment for 1959 1960 Chevy Impala Underbody
All tank straps, mounting brackets, and gaskets are crafted to match the original frame points on 1959 and 1960 Impala B bodies, including Bel Air, Biscayne, and Del Ray editions. This vehicle match ensures that installers can reuse factory holes without drilling or trimming, preserving the classic underbody geometry and appearance. The robust steel straps and hardware clamp the assembly solidly in place, resisting forces from cornering, bumps, and road irregularities. As a result, restorers achieve a professional grade fit that upholds the car's historic lines while delivering modern fueling capability.
Corrosion Resistant Steel Construction and USA Made Components
Every component of the tank kit is manufactured in the USA from corrosion resistant steel, premium gasket materials, and hardened mounting bolts to withstand modern fuel blends and environmental moisture. Strict quality control measures ensure each tank arrives free of surface flaws that could lead to rust or chemical attack. This material selection provides exceptional lifespan even in coastal climates or regions that deploy road salt during winter. Owners can drive with confidence knowing the fuel system will remain robust through daily use, spirited runs, or track day challenges.
