1969-1970 Impala EFI Fuel Tank Kit with 400 LPH Pump
For 1969 and 1970 Impalas undergoing an LS engine swap, steady fuel delivery is non negotiable. This EFI fuel tank kit pairs a deeper steel tank with a 400 LPH Walbro pump to sustain pressure under high demand conditions. Precise alignment with the B Body chassis and a full hardware set help simplify installation for LS engine swaps.
400 LPH Walbro Pump Ensuring Stable Fuel Pressure
The included 400 LPH Walbro pump is engineered to maintain consistent pressure under heavy demand, supporting engines up to 750 horsepower. Its in-tank design positions the pump directly in the fuel column, reducing cavitation and preventing vapor lock during hard acceleration or high loads. By delivering a steady supply of fuel, this module optimizes combustion and throttle response across a wide range of driving conditions.
Custom Tank Profile for Precise B Body Fitment
This fuel tank features a depth increase of three quarters of an inch and a length reduction of five inches compared to the original, creating improved chassis clearance without sacrificing usable volume. The modified profile aligns exactly with the factory crossmembers and sheetmetal contours of 1969-1970 Impala B Body frames, eliminating the need for trimming or filler modifications. As a result, installers achieve a seamless integration that preserves the vehicle's underbody geometry.
Galvanized Steel Construction with Protective Powder Coat
Constructed from robust galvanized steel, the tank resists corrosion in harsh environments and stands up to road debris impacts. A durable powder coat finish adds an extra barrier against moisture and chemical exposure, ensuring the tank's exterior remains blemish-free over time. Together, these treatments extend service life and minimize maintenance intervals, giving you confidence in long-term reliability.
Comprehensive Kit Contents Streamline LS Engine Swap
Beyond the tank and pump, this kit delivers all essential components needed for a thorough installation: an in-tank fuel pump module, calibrated sending unit, tank straps, filler neck, vent filter, gaskets, and mounting hardware. Each piece is engineered to match the kit's geometry and flow requirements, reducing parts sourcing and fitment issues. Whether you're tackling a first swap or refining a restoration, the complete package accelerates the installation process and ensures each connection meets the intended design.
