1970-1972 Chevy Chevelle A-Body LS EFI Fuel Tank Kit
For builders fitting an LS powerplant into a 1970 to 1972 Chevelle A body, stock fuel tanks can lead to clearance conflicts and inconsistent fuel flow. This EFI fuel tank kit reshapes the lower shell with precise cutouts and includes a 255 LPH pump for reliable delivery up to 550 horsepower. Installation uses the factory frame rail mounts and suspension brackets so you can secure the tank without extensive chassis modifications.
Precision Notched Tank Geometry for Exhaust and Tire Clearance
The carefully engineered notched lower shell reshapes the tank to match the contours of a 1970 to 1972 Chevelle A body, creating vital space for both the exhaust pipes and full suspension travel. This tailored geometry prevents contact with the rear axle assembly and maintains factory ride height under load. By eliminating common rub points, the design preserves both handling characteristics and body integrity. Minimal trimming of the floor pan or tubs ensures a clean installation without extensive sheet metal work.
Consistent Fuel Delivery with 255 LPH Walbro Pump
Equipped with a Walbro pump rated at 255 liters per hour, this kit meets the fuel injection demands of LS engines producing up to 550 horsepower. The robust flow rate under wide open throttle and sustained high rpm prevents air ingestion and lean conditions that can harm components. Placing the pump internally limits fuel temperature rise, sustaining steady pressure during extended runs. Reliable volume and pressure translate to smooth acceleration and consistent lap times.
Premium Steel Construction for Enduring Reliability
Fabricated from thick gauge steel and finished with a corrosion resistant coating, the tank withstands debris strikes and chassis flex without deformation. Precision TIG welded seams deliver a leak-free assembly that endures the rigors of spirited street driving and track duty. This rugged build guards the pump module and sending unit against vibration, keeping fuel delivery uninterrupted in every scenario. Added reinforcement at stress points ensures the tank maintains its shape over years of service.
Bolt In Fitment Using Factory Frame Rail Mounts
This kit leverages the stock frame rail mounts and original suspension brackets for a true bolt in installation. Included straps, gaskets, a filler neck, and vent filter mate exactly with the factory fuel lines and plumbing, removing the need for custom adapters or welding. The integrated sending unit fits directly into the new tank flange for accurate fuel level readings without altering the wiring harness. The straightforward process lets builders focus on tuning and performance rather than fabrication challenges.
