1970-1972 Oldsmobile Cutlass LS EFI Fuel Tank Kit
For LS engine installs in a classic Cutlass A Body chassis, this fuel tank kit addresses tight clearance issues and vital fuel supply needs with its precision notched shape. Featuring a 255 LPH Walbro pump inside the tank, it maintains consistent flow under heavy acceleration and supports engine outputs up to 550 hp. The offset notch carves space for larger exhaust tubes and wider sidewall tires without requiring frame modifications. Everything from the sending unit to straps, vent filter, gaskets, and hardware aligns with factory openings for a true bolt in assembly.
Precision Notched Fuel Tank for Exhaust and Tire Clearance
The precision cut notch in the tank shell creates essential room for large diameter exhaust tubes and wide performance tires without any frame or floorpan alterations. Reinforced flanges around the opening maintain structural strength against road vibration and fuel movement. This approach preserves full capacity while solving common clearance conflicts in classic 1970–1972 Cutlass builds. As a result, builders can fit modern headers and tire setups without compromising ground clearance or tank integrity.
Submerged 255 LPH Pump Delivering Reliable Flow to 550 HP
Housed entirely within the fuel body, the 255 LPH Walbro pump benefits from continuous liquid cooling, which reduces heat buildup and operating noise. Its unwavering flow rate supports LS engine demands up to 550 horsepower under hard acceleration or high sustained rpm. Placing the pump in the reservoir also mitigates vapor lock and fuel aeration issues common in high load scenarios. This stable delivery ensures precise injector performance across street and track applications.
Complete EFI Module for Seamless Cutlass Integration
This all-inclusive kit includes the pump module, sending unit, filler neck, vent filter, gaskets, straps and mounting hardware engineered for direct fit in 1970-1972 Cutlass A-Body applications. Each component aligns with factory openings and fastener locations to eliminate the need for additional fabrication or part sourcing. By unifying critical elements in a single solution, installers achieve exact alignment with original contours and maintain leak-free sealing from day one. The result is a cohesive assembly that respects classic lines while enabling modern fuel injection performance.
Streamlined Direct Fit Installation for Home Builders
Designed for a straightforward drop-in replacement, the tank uses precision locating features and OE thread-matched hardware to secure in minutes. No cutting or welding is required on frame rails or floor pans, preserving chassis integrity and ride height. Detailed alignment points guide correct vent and filler tube positioning, simplifying assembly even for novice enthusiasts. This efficient process reduces installation time so builders can get their LS-powered Cutlass back on the road faster.
