1961-1964 Chevy Impala LS EFI Fuel Tank Kit with 255 LPH Pump
For builders installing an LS powerplant in a 1961 through 1964 Chevrolet Impala, the 1961-1964 Impala EFI Fuel Tank Kit with 255 LPH Pump addresses fuel supply requirements with a fully integrated reservoir and pump module. This steel assembly mounts to factory frame rails and retains the original filler neck position while including pump module, sending unit, tank straps, vent filter, gaskets and complete hardware. The 255 LPH electric pump sustains up to 550 horsepower and operates submerged for heat and noise management. Factory style wiring and preassembled seals cut installation time and eliminate compatibility concerns. Backed by corrosion resistant American steel construction, it ensures consistent fuel pressure and precise throttle response across driving conditions.
Engine Swap Compatibility
The 1961-1964 Impala EFI Fuel Tank Kit - 255 LPH Pump is purpose built for EFI conversions in classic GM B bodies. This kit is engineered specifically for 1961-1964 Impala, Bel Air, Biscayne and Del Ray models. Integration with MuscleRods mounting hardware ensures that the LS engine and transmission align with the original chassis points. Proper placement of the engine and correct driveline angles reduce vibration and wear on universal joints, and guarantee that power delivery remains smooth under hard acceleration.
Fuel Delivery Performance
At the heart of this kit lies a 255 LPH Walbro electric pump capable of supporting engines up to 550 horsepower. Its steady flow rate prevents fuel starvation during track launches or extended highway runs, while maintaining a consistent system pressure. This consistency directly translates to sharper throttle response and improved fuel efficiency by matching injector demand more closely, allowing tuners to optimize air fuel ratios across all engine speeds.
Domestic Construction Excellence
Proudly manufactured in the USA, each fuel tank assembly undergoes rigorous quality control. Precision fabrication of the tank shell and meticulous sealing techniques guard against leaks and environmental exposure. Every pump module is bench tested before shipment to ensure that flow rates and pressure curves meet specification. As a result, installers receive a ready to fit package that streamlines the conversion process and minimizes post installation adjustments.
