1970-1972 Chevy Chevelle LS EFI Fuel Tank Kit with 255 LPH Pump
When dropping a modern LS powerplant into a 1970 to 1972 Chevy Chevelle, the factory tank often struggles to meet higher fuel demands under sustained throttle. The 1970 to 1972 Chevelle EFI Fuel Tank Kit - 255 LPH Pump restores consistent pressure by housing a 255 litre per hour Walbro pump within a sealed module that also integrates the sending unit and vent filter. Designed for A Body chassis without any modification, the kit includes straps, gaskets, filler neck and installation hardware for a straightforward bolt in install. Rated to support up to 550 hp, it keeps the tank pickup submerged to prevent vapour build up at high rpm. Manufactured in the USA from corrosion resistant materials, this assembly is compatible with both LS and LT engine swaps.
Complete Fuel System Upgrade
Our 1970 to 1972 Chevelle EFI Fuel Tank Kit with 255 LPH Pump transforms the stock fuel system into one ready for serious performance. Designed to support up to 550 HP on LS configurations, this kit includes a custom tank with integrated sender and mounting hardware.

Consistent Fuel Delivery
At the heart of this kit is a 255 LPH Walbro fuel pump engineered for even output under high demand. The unit resists starvation during cornering or hard acceleration and maintains stable pressure at elevated engine speed.
