1970-1972 Chevelle A-Body EFI Fuel Tank Kit for LS and LT Engines
Fitting a modern LS or LT powerplant into a 1970 to 1972 Chevrolet Chevelle A Body often exposes interference between the factory tank and rear exhaust pipes plus wheel assemblies. This EFI fuel tank kit for 1970 to 1972 Chevelle combines a precision notched steel shell with a 400 LPH Walbro pump to maintain consistent rail pressure under heavy throttle while clearing tight spaces. A formed shell that matches original chassis rails removes the need for cutting sheet metal and the complete hardware package delivers a ready to install solution for street or track applications.
Precision Notched Tank Profile for Exhaust and Wheel Clearance
The tank shell is CNC formed to mirror the original frame rails on 1970 to 1972 Chevelle bodies. This purpose built contour provides precise clearance for exhaust pipes and rear wheels without any cutting or reshaping of the floor pan. By preserving the structural integrity of the shell, the design reduces the risk of leaks or deformation under load. Installers benefit from a direct bolt in fit that follows factory chassis lines and accelerates the overall swap process.
Integrated 400 LPH Walbro Pump Ensuring Stable Fuel Pressure
At the heart of the kit is a high-flow 400 LPH Walbro pump selected for its ability to sustain steady rail pressure in engines up to 550 horsepower. Its internal mesh filter traps debris before it reaches critical passages while damping operational noise. The pump's bleed design resists cavitation when fuel levels are low and maintains consistent delivery under full throttle demands. Drivers will notice smooth power delivery without lean spikes during spirited acceleration.
Comprehensive Ready to Install Components for Simplified Swap
This kit includes a complete set of components tailored to the Chevelle's body openings and frame mounts. A calibrated sending unit provides accurate gauge readings at every fuel level while the formed filler neck and vent filter ensure proper vapor management. Heavy duty gaskets and straps, along with all necessary mounting hardware, eliminate guesswork during installation. The result is a ready to install assembly that reduces labor time and potential fitment issues.
Durable Steel Construction with Internal Protective Seal
The tank itself is crafted from corrosion resistant steel with precision welded seams at high stress zones. Thick straps secure the unit firmly to the chassis, even under aggressive cornering or road vibration. Inside, a protective coating shields surfaces from ethanol mixes and moisture, extending service life in varied climates. These measures yield a robust foundation that can withstand the demands of both daily driving and spirited performance applications.
