1961-1964 Chevy Impala LS EFI Fuel Tank Kit with 255 LPH Pump
When updating a classic Impala chassis for modern LS power, reliable fuel supply becomes critical, and the 1961 through 1964 Impala EFI Fuel Tank Kit with 255 LPH Pump addresses this need with precision engineering. This steel fuel tank matches original mount locations on the B Body frame and retains factory fill neck alignment for installation without modification. Integration of the 255 LPH Walbro electric pump, sending unit and filter in a single assembly ensures even pressure and prevents vapor lock during spirited driving. Built in the United States, the unit delivers quieter operation and long service life under all conditions.
Precision Fit for 1961 through 1964 Impala Frame
This fuel tank is crafted to match the exact contours and mounting points of the B Body chassis used in Impala models built from 1961 through 1964. By aligning with factory strap bosses and preserving the original filler neck alignment, it installs without cutting or welding, maintaining the stock ground clearance and body lines. Builders upgrading to LS power benefit from a solution that bolts in place just like the original tank, reducing installation time and complexity. The result is a seamless integration that honors the classic appearance while accommodating modern EFI demands.
Submerged Module for Cooler Operation and Quiet Performance
The 255 LPH Walbro pump is housed inside the tank, fully immersed in fuel to draw heat away from its motor and extend service life. This in-tank placement also suppresses pump noise, delivering a quieter cabin experience compared with externally mounted units. Integration of the sending unit, filter and pump in a single module ensures consistent fuel pressure and virtually eliminates vapor lock under heavy load. Drivers will notice uniform flow at all engine speeds and reliable delivery even during spirited acceleration.
255 Liter per Hour Pump Supports 550 Horsepower LS Builds
With a maximum flow rate of 255 liters per hour, this in-tank pump module meets the fuel delivery needs of LS engine swaps producing up to 550 hp. The ample capacity sustains sharp throttle response and a stable fuel-to-air ratio from idle through full throttle, preventing lean spots that can harm performance. Enthusiasts will appreciate the confident acceleration and consistent power delivery on the street or strip. This level of output compatibility makes it suitable for everything from mild street engines to high-output performance builds.
Complete Kit of Components for Streamlined EFI Installation
Every necessary piece is included to complete a plug and play EFI upgrade on classic Chevy B Body frames. The kit arrives with tank straps, filler neck, vent filter, gaskets and mounting hardware along with the fuel pump module and sending unit. By supplying all required parts in one package, it eliminates the need to source individual components and reduces downtime. Builders can focus on wiring and tuning their LS swap rather than hunting for compatible pieces, accelerating the path from chassis prep to engine start.
