1970-1972 Chevy Chevelle LS EFI Fuel Tank Kit with 255 LPH Pump
Anyone fitting an LS power plant into a 1970-1972 Chevelle will need a reliable fuel supply that keeps pace with engine demands. This fuel tank kit is custom engineered for the A-Body Chevelle to support up to 550 horsepower and maintain steady flow during spirited driving. It includes a 255 LPH Walbro pump and a precision sending unit that assure consistent fuel delivery and LS and LT compatibility for a smooth swap process.
Optimized Fuel Delivery for 550 Horsepower
The heart of this kit is the 255 LPH Walbro pump, calibrated to sustain up to 550 hp without risking fuel starvation. By matching pump flow to engine demand, it ensures the engine receives an ample fuel supply during wide-open throttle and aggressive acceleration. This steady delivery helps maintain consistent air-fuel ratios, reducing the chance of lean spikes that can lead to detonation. Enthusiasts will notice smoother throttle response and stable performance under load, especially during spirited driving or track use.
Precision Fit for 1970-1972 Chevelle A-Body Chassis
Every tank and bracket is tailored specifically for the Chevelle's A-Body frame rails, allowing for a drop-in installation with no cutting or welding required. The custom contours align with factory mounting points, so the kit sits true and square for optimal clearance around rear suspension components. This vehicle-specific fitment simplifies installation and preserves original undercarriage integrity, making it ideal for restorations or swap projects that demand factory-style precision.
Integrated In-Tank Module for Consistent Performance
This all-in-one assembly houses the fuel pump, sending unit, and internal filter in a sealed module that shields critical parts from heat soak and vibration. The built-in vent filter balances tank pressure to prevent vapor lock while the precision sending unit delivers accurate level readings to the dash. Engineered gaskets and quality hardware complete the seal, eliminating leaks and minimizing the chance of air ingestion that can degrade pump efficiency.
Crafted in USA for Lasting Quality
Manufactured domestically with strict quality controls, this EFI fuel tank kit reflects the dedication to durability and performance expected by classic car builders. Components undergo rigorous inspection before assembly, ensuring weld integrity and material uniformity in critical areas. By sourcing in-country, the kit supports quicker lead times and consistent part availability, giving Chevelle owners confidence in both supply chain reliability and long-term serviceability.
