1970-1972 Oldsmobile Cutlass A-Body EFI Fuel Tank Kit with 255 LPH Pump for LS Swaps
The Cutlass EFI Fuel Tank Kit designed for 1970 to 1972 chassis solves tight frame and exhaust clearance obstacles in Oldsmobile A Body LS swaps. By carving a precision notch into the tank shell this design frees up room for larger headers and wider tires without altering the floor pan. Positioning the 255 LPH pump inside maintains reliable fuel delivery for engines up to 550 horsepower under sustained load. Installers benefit from a complete set of factory matched components for a true drop in fit that preserves ground clearance.
Precision Notch Design for Enhanced Header and Tire Fitment
The tank shell features a precision notch sculpted into the rear wall to clear larger exhaust headers and wider tire setups while retaining the original floor pan. Reinforced edges around the cut maintain structural integrity under chassis flex and fuel slosh, ensuring capacity remains consistent even during hard cornering. This sculpted cavity resolves common interference issues in LS engine retrofits, allowing modern performance hardware to be installed without bending sheet metal. By preserving ground clearance and stock floor height, the design keeps the classic chassis appearance intact. Builders gain freedom to select aggressive exhaust and tire combinations with confidence in fitment.
Integrated 255 LPH Pump for Reliable High-Load Flow
The in-tank 255 LPH pump delivers a continuous stream of fuel to engines producing up to 550 horsepower, minimizing the risk of vapor lock under prolonged high-rpm operation. Submerged installation keeps the module immersed, which provides natural cooling that stabilizes internal temperatures and lowers the chance of cavitation. Placing the pump inside the tank body also reduces noise and vibration compared to external units, creating a quieter ride. The module’s consistent output pressure ensures injectors receive precise fuel volume in both street cruising and spirited track driving. Operators benefit from steady delivery under demanding conditions without the need for supplemental regulators or external coolers.
Complete Upgrade Kit with Factory Matched Hardware
This comprehensive package provides every component necessary for an EFI conversion in 1970–1972 Oldsmobile Cutlass A-Body applications, including the fuel pump module, sending unit, tank straps, filler neck, vent filter, gaskets and mounting hardware. Each part aligns with original factory openings and maintains correct thread and seal dimensions for a true direct fit. By supplying the full complement of seals and fasteners, the kit eliminates multiple trips to parts suppliers and prevents misfit issues. Installers can spend less time sourcing odd-sized gaskets and more time on tuning and performance. The result is a turnkey solution that integrates seamlessly with stock chassis architecture.
Straightforward Installation That Preserves Chassis Integrity
Designed for easy assembly in a home garage, the tank drops into place and mates with existing mounting points without any frame alterations. Preformed straps and precision locating tabs guide alignment, guaranteeing correct ground height and proper alignment of fuel lines. This method reduces fabrication steps and lowers the chance of installer error, making it accessible for enthusiasts with basic hand tools. Once bolted in, the system retains the factory ride height and maintains proper line routing to the engine bay. End users achieve a clean, reliable installation that upholds the structural and functional integrity of the original chassis.
Built for direct fit and consistent performance, this kit pairs perfectly with a Larger capacity fuel pump Kit at 400 LPH like our 1970-1972 Cutlass 400 LPH pump Tank Kit (notched).
