LS Swap EFI Fuel Tank Kit for 1970-1972 Oldsmobile Cutlass
When grafting an LS engine into a 1970-1972 Oldsmobile Cutlass reliable fuel supply is essential to prevent lean conditions under load. This EFI fuel tank kit houses a 255 LPH pump, fuel level sender, and all required mounting hardware for a clean A-Body installation. Built to work with both returnless and traditional fuel systems and stainless steel lines, it ensures correct fitment and steady flow for setups up to 550 horsepower.
Engineered Fit for 1970 to 1972 A Body Cutlass
This fuel tank kit is sculpted to match the contours of the Cutlass frame rails from 1970 to 1972, ensuring precise alignment with minimal adjustment. By replicating the original mounting pad geometry, it preserves factory clearances and avoids interference with suspension components. The included straps and filler neck mount exactly where the stock tank did, so installers can rely on a direct swap without metal fabrication. This tailored fitment not only speeds up assembly but also maintains the integrity of the A Body structure for long term service.
Advanced 255 LPH Walbro Pump for Steady Flow
At the heart of the module sits a 255 LPH Walbro electric pump designed to feed LS engines up to 550 horsepower without pressure drop under heavy load. Its bypass return valve ensures stable fuel pressure in both returnless and traditional systems, adapting to the needs of modern engine management. The unit's internal strainer protects against debris and the robust motor windings resist heat soak during extended operation. This combination of flow capacity and consistency keeps injectors fed at a constant rate for reliable throttle response at any rpm.
Complete Kit Streamlining Your LS Swap Project
Every element needed to finish the fuel delivery portion of your LS conversion arrives in one box, eliminating trips to the parts store. Alongside the pump module and fuel level sender, you receive tank straps, vent filter, gaskets, hardware and a precisely formed filler neck to mate with stock openings. These components are packaged to reduce guesswork, so even those new to fuel tank work can follow a straightforward sequence. The result is a finished installation in far less time and with fewer alignment checks than piecing together separate parts.
US Built Craftsmanship for Reliable Performance
Manufactured entirely in the United States, this kit benefits from close quality control at every step, from material selection to final assembly. The corrosion-resistant steel tank and precision molded plastic components undergo rigorous testing to meet demanding automotive standards. By choosing domestic production, tolerances remain tight and batch consistency stays uniform, leading to dependable operation mile after mile. This focus on American built quality translates into fewer service events and a fuel system that stands up to both daily driving and spirited track use.
