1970-1972 Chevy Chevelle LS and LT EFI Fuel Tank Kit
Whether you are swapping an LS or LT engine into a 1970 to 1972 Chevelle A Body this notched fuel tank kit resolves tight clearance around exhaust pipes and rear wheels while preserving chassis alignment. Its shell is CNC formed to mirror factory rails so installers avoid cutting or reshaping floor pans and secure the tank with straps. At the heart of the assembly the 400 LPH Walbro pump maintains consistent fuel pressure under full throttle and resists cavitation when levels drop. Complete with calibrated sending unit vent filter mounting straps and all hardware the kit streamlines installation for spirited street use while protecting against moisture and ethanol.
Precision Notched Shell Contour for Optimal Clearance
The custom notched profile of the fuel tank is CNC formed to follow the factory rail geometry of 1970 to 1972 Chevelle A-Body frames, delivering exact fitment around rear exhaust bends and rear wheel assemblies. By mirroring the original chassis lines, this design removes the need for cutting or reshaping floor pans and preserves structural integrity. Installers gain a bolt-in solution that minimizes distortion risks and maintains leak-free performance under the stresses of spirited driving.
400 LPH Walbro Pump for Consistent Rail Pressure
At the heart of the assembly lies a 400 liter-per-hour Walbro pump selected for its ability to support engines up to 550 hp or equipped with forced induction. Its internal mesh filter traps contaminants before they can enter precision fuel rails, while an integrated bleed circuit resists cavitation as fuel levels drop. The result is stable pressure delivery across all throttle positions and smooth power transitions without lean spikes during aggressive acceleration.
Complete Ready to Install Fuel System Kit
This kit bundles every component required for a streamlined LS and LT swap: the in-tank module with pump, calibrated sending unit, formed filler neck, vent filter, heavy-duty straps, resilient gaskets and all mounting hardware. Each part is purpose-engineered for the Chevelle body openings and frame mounts, reducing fitment checks and labor time. Technicians appreciate the cohesive package that simplifies installation for both street and track applications.
Robust Steel Shell with Internal Corrosion Protection
Crafted from corrosion-resistant steel and reinforced with precision-welded seams at high-stress zones, the tank shell offers a sturdy foundation for reliable operation. Thick mounting straps secure the unit firmly under cornering loads and road vibration. Internally, a protective coating shields surfaces from moisture and ethanol blends, extending service life in varied climates. This combination of strength and protection ensures dependable performance from daily driving to spirited outings.
