1964-1967 Oldsmobile Cutlass A-Body Fuel Tank Kit for LS and LT Engine Swaps
When tackling an LS or LT swap in a classic 1964 to 1967 Cutlass A Body chassis you need precise fuel delivery under high demand. This EFI Fuel Tank Kit is engineered to drop directly into the factory underbody recess without modification while packing a 400 LPH pump calibrated to support over 550 horsepower. Installation hardware aligns with original frame openings and includes straps, gaskets and vent filter for a straightforward fit. Builders will value its accurate sending unit that mirrors stock resistance curves for reliable gauge feedback on street and track.
400 LPH Pump Ensuring Consistent Fuel Supply
The 400 LPH Walbro pump, situated inside the tank, is calibrated to maintain steady fuel pressure even when output exceeds 550 horsepower. By fully submerging the pump assembly, the surrounding fuel acts as a natural heat sink that prevents excessive thermal buildup and extends component life. Consistent rail pressure is maintained during sudden throttle shifts and sustained high engine speed, eliminating lean spots or hesitation under load. Built with reliable electrical connections and optimized flow passages, this pump supports supercharged or naturally aspirated LS and LT engines with minimal voltage loss and predictable performance at all times.
Precision Sending Unit Mirroring Factory Gauge Response
The fuel sending unit replicates the stock resistance curve of the original Oldsmobile system to deliver accurate level readings on the factory gauge. Its smooth float arm travels through the full range of fuel depth without binding, while durable materials resist corrosion from additives and ethanol blends. By matching the vehicle's native electrical characteristics, this unit prevents sudden needle swings or false empty warnings that are common with generic replacements. Drivers benefit from stable feedback, reducing fuel range anxiety and ensuring they can focus on performance rather than guesswork.
Direct Fit Installation in 1964-1967 Cutlass A Body
This fuel tank kit drops into the factory underbody recess of 1964 to 1967 Cutlass A Body models without any cutting or fabrication. All mounting hardware, including tank straps, gaskets, vent filter, filler neck, and bolts, aligns precisely with original frame openings. Technicians can attach components using standard hand tools, saving time and labor costs. The low profile design preserves the classic undercarriage appearance while delivering modern EFI capability. This straightforward fitment respects the vehicle's heritage and simplifies the swap for both street and track applications.
American Craftsmanship and Component Durability
Manufactured in the United States under strict quality control, every pump, sending unit, and piece of hardware undergoes performance and corrosion testing before assembly. Domestic production allows for traceable material sourcing and fast access to replacement parts, ensuring build consistency and long term support. Straps and gaskets are engineered to resist chassis flex and road vibration, maintaining a leak free seal season after season. This commitment to local craftsmanship offers builders confidence in the system’s endurance, whether cruising city streets or pushing the limits on the track.
