1961-1964 Chevy Impala EFI Fuel Tank Kit with 255 LPH Pump for LS Swaps
Swapping an LS engine into a 1961-1964 Chevy Impala creates new demands for the fuel system and the factory tank design often falls short. The 1961-1964 Impala EFI Fuel Tank Kit - 255 LPH Pump delivers an in tank module with a 255 LPH Walbro pump, fuel sending unit and all mounting hardware to support engines up to 550 horsepower. With precise body specific fitment for B-Body Chevrolet models this kit simplifies installation and ensures consistent flow for throttle response and economy.
In Tank Pump Module Design Ensures Reliable Delivery
The integrated in tank pump module positions the Walbro unit directly in the fuel reservoir to maintain constant cooling by the liquid and to reduce noise. This submersion leads to uniform pressure at all engine speeds and helps prevent vapor lock during extended runs. By combining the pump, sending unit and filter in one compact module, installation time is reduced and alignment with factory mounting points is preserved for precise fitment.
255 LPH Walbro Pump Suits High Power Engines
With a flow capacity of 255 liters per hour, the Walbro pump delivers sufficient volume to support power levels reaching 550 horsepower. This ensures the most demanding LS engine builds receive the fuel they require from idle through wide open throttle. The steady delivery translates into sharper throttle response and helps maintain optimal air fuel ratio, which in turn supports efficient combustion and improved fuel economy on every drive.
Complete Kit Streamlines LS Engine Swap Integration
The kit includes all necessary hardware from tank straps and filler neck to gaskets and vent filter, creating a single solution for converting vintage Impalas to modern fuel injected drivetrains. By matching original mounting points on the 1961 to 1964 B Body chassis, this kit removes guesswork and reduces fabrication time. The accurate fuel sending unit works with factory gauges to provide precise level feedback and consistent performance under varying conditions.
American Made Quality Ensures Long Term Reliability
Proudly produced in the United States, this fuel tank kit reflects strict quality controls and the use of durable materials in every component. Each pump module and sending unit undergoes validation to meet the expectations of classic car builders seeking enduring performance. The attention to detail in strap design and gasket fitment minimizes leaks and stands up to road vibration over years of service.
