1961-1964 Chevy Impala LS EFI Fuel Tank Kit with 255 LPH Pump
A classic Impala restorer tackling an LS swap will value the EFI fuel tank kit designed to bolt directly to the frame rails of a 1961 through 1964 Impala and deliver reliable injection performance. Housed within a precision steel reservoir the factory style installation accommodates the factory filler neck location while the 255 LPH Walbro module keeps heat and noise in check and maintains the steady flow demanded by engines up to 550 hp. Integrated wiring harness along with preassembled mounting straps and gaskets slash installation time and eliminate compatibility concerns for both professional installers and home builders. Whether this build lives as a daily driver or track day machine this fuel system solution ensures the margin required for stable pressure and crisp throttle response under varying conditions.
Precision Alignment with 1961 through 1964 Impala Frame Rails
The steel reservoir is engineered to match the original B Body chassis rails of a 1961 through 1964 Impala without any frame alterations. By preserving the factory filler neck location and strap bosses, this assembly installs in minutes and retains the vehicle's authentic ground clearance and stance. Technicians benefit from a true drop in solution that keeps the body proportions exactly as designed by Chevrolet. With no need for adapters or custom brackets, installers avoid costly modifications and ensure the fuel system integrates invisibly.
Immersion Cooled Pump for Temperature Control and Noise Reduction
The 255 LPH Walbro pump sits fully submerged within the tank to draw surrounding fuel over its motor housing. This constant bath of liquid helps dissipate heat and slows wear on internal components. At the same time immersion isolates vibration so flow noise is kept to a minimum even under heavy engine load. By combining pump, filter and sending unit into one sealed module, the design also cuts down on plumbing joins and potential leak points. The outcome is a quieter cabin and a cooler fuel source that holds firm pressure in all conditions.
Consistent Fuel Flow for Up to 550 Horsepower Engines
Engineered to support up to 550 horsepower LS applications, the 255 LPH pump maintains a steady flow from idle to wide open throttle. This reliable supply keeps the air to fuel ratio consistent, preventing lean conditions that can harm internal parts. Drivers will notice crisper throttle response and improved fuel efficiency during both casual cruising and spirited runs. The stable pressure also protects against vapor lock, giving builders the confidence to push their classic Impala hard on street or track. It delivers the margin needed for safe, high output service.
All in One EFI Conversion Kit for Simplified Installation
This kit delivers every component required for a complete EFI fuel upgrade in one integrated package. The in tank module, sending unit, tank straps, filler neck, vent filter, gaskets and hardware arrive ready for assembly. An integrated wiring harness and preinstalled seals eliminate guesswork and sourcing delays. Installers simply bolt the tank to the factory rails and tie into existing fuel lines and engine wiring - no drilling or welding needed. This streamlined approach lets builders focus on calibration and tuning instead of tracking down parts.
