70-72 Oldsmobile Cutlass A-Body LS Fuel Tank with 255 LPH Pump

Supporting engines up to 550 hp, the notched tank kit delivers precise 255 LPH fuel flow with an integrated Walbro pump and tailored dimensions for 1970 to 1972 Cutlass A Body LS conversions to preserve full tire and exhaust clearance. Complete with all necessary fittings, hardware and installation components, it guarantees reliable delivery under high loads and hard cornering while simplifying the upgrade with a straightforward DIY fitment.

1970-1972 Oldsmobile Cutlass EFI Fuel Tank Kit for LS Swaps

When tight frame and exhaust clearances stall an LS swap, this 1970-1972 Cutlass EFI Fuel Tank Kit offers a notched tank that frees space for larger headers and wide sidewall tires without altering the floor pan. By placing a 255 LPH pump inside the tank body, it ensures steady flow under heavy acceleration and supports up to 550 horsepower while reducing risk of vapor lock on long runs. Components from the sending unit and filler neck to straps and gaskets match factory openings on the A Body chassis for a true bolt in fit. Installers can achieve a straightforward drop in replacement that preserves chassis integrity and maintains proper ground clearance in classic Cutlass builds.

Precision Notched Shape for Enhanced Exhaust and Tire Adaptation

The carefully engineered notch in the tank shell creates dedicated clearance for larger exhaust tubes and broader tire sidewalls without altering the original floor pan. Reinforced edges around the cut maintain structural integrity under chassis flex and fuel slosh, preserving full capacity even in spirited driving. This precision shaping solves a common bottleneck in LS conversions by freeing up space without compromising ground clearance or requiring frame modifications. Builders gain the freedom to fit modern headers and performance rubber while retaining the classic Cutlass floor profile.

Submerged 255 LPH Walbro Pump Ensuring Steady Delivery

Housing the 255 LPH Walbro pump entirely inside the fuel body means continuous liquid cooling that keeps operating temperatures low and minimizes vapor formation. This in tank placement sustains a consistent flow rate up to 550 horsepower, even under high sustained rpm or hard acceleration. By preventing aeration and vapor lock, the design ensures precise injector performance in both street cruising and track sessions. The pump's internal module also cuts down on noise and vibration, delivering a quieter installation without the need for external pump mounts.

All Inclusive Assembly Designed for 1970 1972 Cutlass A Body

Every component from the sending unit and filler neck to straps, gaskets and vent filter is engineered to match factory openings on the Cutlass A Body chassis. This kit brings together all essential parts in one package, eliminating the hunt for separate pieces and reducing installation time. OE thread matched hardware and precision locating features allow for a true bolt in fit with no cutting or welding on frame rails or floor pans. Even novice installers can follow the exact alignment points to achieve leak free sealing and maintain original ride height.
