1970-1972 Chevy Chevelle A-Body LS and LT EFI Fuel Tank Kit
An LS or LT swap in a 1970-1972 Chevelle A-Body demands a fuel delivery solution that aligns precisely with the chassis under load and the 1970-1972 Chevelle EFI Fuel Tank Kit with its 400 LPH pump addresses that need. A CAD shaped flange matches the original mounting rails without any sheet metal work ensuring correct tank angle and leak free connections. Within the heavy gauge steel shell a USA built 400 LPH Walbro pump teamed with internal baffling traps fuel at the pickup to prevent starvation during hard cornering and rapid deceleration. All hardware and fittings arrive matched to the factory undercarriage so installation moves smoothly and the Chevelle's original look remains intact.
Precision CAD Flange for Perfect Chassis Alignment
The custom shaped flange is crafted using computer aided design to mate exactly with the 1970-1972 Chevelle A-Body mounting rails, ensuring a seamless fit under the chassis. By replicating factory mounting points it removes the need for any sheet metal modification, preserving the vehicle's original underbody profile. This exact match also maintains the correct tank angle, preventing fuel spills or leaks at the filler neck during both regular driving and spirited cornering. Uniform load distribution across the flange reduces stress on the mounting straps, keeping the assembly stable under acceleration, braking, and lateral forces. As a result, the installation appears factory fresh while providing the firm foundation required for modern EFI fuel delivery.
USA Built 400 LPH Fuel Pump Sustains Over 550 HP
At the heart of this kit is a Walbro fuel pump assembled in the United States and rated at 400 liters per hour, capable of supporting more than 550 horsepower in naturally aspirated or supercharged LS and LT engines. Its precision engineered impeller and integrated pressure regulator maintain a consistent flow rate even at wide open throttle, preventing lean conditions that can lead to detonation or component damage. The pump housing and internal components are designed to withstand high fuel temperatures and the rigors of track or street use, ensuring dependable operation in demanding environments. Rigorous quality control during manufacturing guarantees a quiet, vibration free performance that contributes to driver confidence and engine reliability. By sustaining stable pressure under sustained high load, this pump meets the exacting needs of modern engine swaps in classic Chevelles.
Internal Baffle System Ensures Constant Fuel Flow
Inside the heavy gauge steel tank, a network of baffle plates is positioned around the pickup tube to trap fuel during hard cornering, rapid acceleration, and sudden deceleration. This internal arrangement breaks up the natural sloshing motion of fuel, preventing air pockets from forming around the inlet and starving the pump. By managing fluid movement within the shell, the baffle system delivers a continuous supply of fuel and stable inlet pressure, even when the vehicle is driven aggressively. This design is essential for high output applications where any interruption in fuel delivery can lead to hesitation, power loss, or engine damage. Drivers benefit from seamless throttle response and consistent performance whether on the street or the track.
All in One Kit Streamlines Installation and Preserves Style
This comprehensive fuel tank solution combines the pump module, sending unit, tank straps, filler neck, vent filter, gaskets, and all required hardware into one matched package for the 1970-1972 Chevelle A-Body. Builders avoid the common pitfalls of parts sourcing and compatibility, cutting overall labor time by following a clear installation path. Each component is preassembled and tested as an integrated system to guarantee a precise fit with factory rails and body contours, so the undercarriage retains its classic appearance. Corrosion resistant fittings and heavy duty materials deliver lasting service life while simplifying maintenance. The end result is a professional upgrade that enhances modern EFI capability without compromising the Chevelle's authentic styling.
