1959-1960 Chevy Impala EFI Fuel Tank Kit for LS Swaps
When fitting an LS engine into a 1959-1960 Chevy Impala B Body, reliable fuel delivery is non negotiable and this Impala EFI Fuel Tank Kit 255 LPH Pump provides a direct solution by housing a 255 LPH pump inside a precision molded tank that keeps your factory floor pan intact. Precision molding against the Impala rails ensures correct ride height without trimming or welding. Housed components include the pump module, sending unit, filler neck, straps and gaskets so installers have everything needed in one package. The calibrated pump supports up to 550 hp to guard against fuel starvation during spirited driving.
Precision Molded Fuel Tank Preserves Impala Floor Pan
The fuel tank is engineered to match the 1959–1960 Impala B Body frame rails with exacting precision, preserving the original floor pan without any trimming or welding. This close contouring maintains the factory ride height and structural integrity, so weight distribution remains true to the car's design. Installers benefit from a drop-in fit that locks into place on the rails, eliminating alignment shifts over time. By retaining the stock mounting points, you safeguard the chassis and avoid aftermarket modifications that could compromise durability.
Efficient 255 LPH Walbro Pump for Reliable LS Fuel Supply
At the heart of the tank sits a 255 liter-per-hour Walbro pump calibrated to feed LS engines up to 550 horsepower. Locating the pump module inside the tank keeps fuel cool and pressurized at the source, dramatically reducing vapor lock risk under hard acceleration or sustained cornering. The internal electronics remain hidden, simplifying wiring and minimizing potential leaks. This arrangement also positions the sending unit for consistent level readings, ensuring your factory gauge delivers accurate feedback at all times.
All-in-one Installation Package Streamlines Assembly
Every component needed for a complete swap arrives ready to install, cutting out trips to multiple suppliers and guesswork on fitment. Included are the fuel pump and module, sending unit, tank straps, filler neck, vent filter, gaskets, and all mounting hardware sized for Impala B Body rails. Tank straps replicate the original dimensions to secure the assembly without shims or adjustments. Focusing on purpose-built parts reduces the number of joints and leak paths, allowing a tidy, time-saving assembly process.
Seamless Classic Look with Modern EFI Integration
This fuel tank kit lets your Impala retain its vintage appearance while delivering the performance of modern electronic fuel injection. All electronic elements are concealed within the tank, leaving the exterior untouched and preserving the clean body lines beneath the trunk floor. The filler neck and vent filter mount in factory locations, so underbody contours stay consistent with stock sheetmetal. By merging period-correct style with EFI efficiency, you gain reliable fuel delivery without sacrificing the car’s timeless appeal.
