1970-1972 Chevy Chevelle LS EFI Notched Fuel Tank Kit with 255 LPH Pump
When fitting an LS engine into a second generation A body Chevelle, factory tank clearances can lead to fuel supply issues and tricky exhaust alignment. The 1970 to 1972 Chevelle EFI Fuel Tank Kit with 255 LPH pump and notched design solves this by reshaping the tank with precision cutouts for exhaust and tire clearance, and its 255 LPH flow rate ensures consistent fuel delivery to your LS engine. Built to support up to 550 horsepower, this kit resists wear under demanding driving conditions and maintains consistent performance. Installation aligns with the stock frame rails and suspension points, so you can finish your swap without extensive modifications.
Precision Notched Tank Geometry for Exhaust and Tire Fitment
The notched design of this fuel tank is engineered with exact cutouts that match the contours of the Chevelle's rear end, providing necessary clearance for both the exhaust and suspension travel. By reshaping the lower tank shell, the kit prevents interference with the axle assembly and allows targeted alignment under full load. This approach eliminates the common issue of rub points and ensures that an LS engine conversion maintains factory ride height and handling characteristics. The result is a secure fit that requires minimal modification to the body tub and floor pan.
255 LPH Walbro Pump Ensuring Steady Fuel Delivery for LS Engines
Equipped with a high capacity Walbro unit, this system delivers 255 liters of fuel per hour to meet the demands of modern LS fuel injection setups. It supports engine outputs up to 550 horsepower, offering stable pressure under both wide open throttle and sustained high rpm. Consistent fuel volume is critical to prevent lean conditions that can damage internal engine components during spirited driving or track use. The in-tank location also reduces heat soak, maintaining efficient flow even under prolonged high load.
Rugged Construction for Resistance to Stress and Wear
Built from thick gauge steel and finished with a corrosion-resistant coating, the tank withstands road debris impact and chassis flex without deforming. All weld seams are precision-machined to ensure a leak-free assembly over years of service. This robust build can handle rapid pressure changes and repeated fuel sloshing without fatigue in the structure or internal components. With its solid construction, the kit protects the pump module and sending unit from vibration and keeps the fuel delivery network secure.
Seamless Integration with Chevelle A Body Frame Rails
This kit leverages the factory mounting points on 1970-1972 A body frame rails and original suspension brackets for a true bolt-in installation. Included straps, gaskets, and a filler neck are designed to mate precisely with stock fuel lines and vent plumbing, eliminating the need for custom adapters or welding. The sending unit installs directly into the new tank flange, retaining accurate fuel level readings without altering the wiring harness. This streamlined process lets builders focus on performance tuning rather than fabrication.
