LS EFI Fuel Tank Kit with 255 LPH Pump for 1970-1972 Chevy Chevelle A-Body
When installing an LS engine into a 1970-1972 Chevelle A-Body, maintaining a consistent fuel flow becomes critical and this EFI fuel tank kit with its 255 LPH pump is engineered to meet that demand. Each component fits directly to factory mounting points for a drop-in installation that eliminates the need for cutting or welding. A precision sending unit and internal filter work with the pump to keep fuel pressure steady for up to 550 horsepower, helping to prevent lean conditions during spirited driving. Tank materials and hardware are selected for durability and tested to withstand heat soak and vibration on classic A-Body chassis.
Engine Grade Fuel Pump Matching LS Power Demands
The 255 LPH Walbro pump in this kit is calibrated to keep up with an LS engine producing up to 550 horsepower, ensuring your Chevelle never runs lean under heavy load. By maintaining steady flow during wide open throttle and rapid acceleration, it stabilizes air-fuel ratio and reduces the risk of detonation. Drivers will experience more consistent performance at high RPM and improved throttle response when pushing the car on the street or at the track.
Drop in Fit Tailored to 1970 to 1972 A-Body Frame Rails
Every tank and bracket aligns precisely with the 1970 to 1972 Chevelle A-Body chassis, allowing for installation without cutting or welding. This tailored fit preserves original undercarriage geometry and clears suspension components for safe operation. With factory style mounting points, the kit delivers a secure installation that simplifies restoration projects and engine swap workflows.
Sealed In Tank Module for Consistent Flow and Protection
The integrated in-tank assembly combines pump, sending unit, and filter in a sealed housing that shields critical parts from heat soak and vibration. An internal vent filter prevents vapor lock while precise gaskets and hardware stop leaks and air ingress. This robust design maintains fuel pressure stability during spirited driving and helps extend pump life under the harsh conditions of a classic chassis.
