LS EFI Fuel Tank Kit for 1978-1987 Oldsmobile Cutlass
Swapping an LS engine into a 1978 to 1987 Oldsmobile Cutlass four door often runs into fuel starvation during hard throttle pulls but this EFI Fuel Tank Kit resolves that with a direct fit design. It installs in the stock tank cavity and bolts to factory mounts while using the original filler neck to preserve sensor accuracy and full underbody clearance. A 255 LPH pump with a brushless motor sustains steady flow to support up to 550 hp and the cartridge system lets you swap in a 400 LPH unit without new brackets or wiring changes. Stainless steel straps and American made gaskets resist corrosion and vibration for dependable service.
Precision Brushless Pump Design for Reliable LS Fuel Flow
The heart of this kit is a 255 LPH brushless pump engineered specifically for LS engine swaps. By removing internal brushes the motor generates less heat and experiences lower wear over thousands of miles. Precision balancing of the spinning assembly and a fully sealed housing guard against vibration and moisture intrusion under hard acceleration. These qualities deliver smooth throttle response across the entire rev range and maintain steady pressure for engines up to 550 hp.
Modular Cartridge Upgrade Path for Increased Capacity
A standout feature is the modular cartridge system that accommodates a 400 LPH unit without altering mounting brackets or rewiring the harness. Simply swap the pump module to support forced induction setups or aggressive cam profiles. This tool free changeover eliminates custom plumbing and cuts downtime during power upgrades. As performance targets grow, the kit evolves with the build rather than requiring a full refit.
Direct OEM Fitment in 1978 to 1987 Cutlass 4 Door Fuel Cavity
This assembly is crafted to drop into the original tank cavity of 1978 to 1987 Cutlass 4 door models, securing to factory mounting points for a seamless fit. Retaining the stock filler neck preserves underbody clearance and maintains accurate level sensor readings. The pre wired sending unit plugs into the vehicle harness without adapters or extensions. Installers benefit from a straightforward process that mirrors factory installation for a professional result.
American Made Components for Enhanced Durability
Every gasket, strap and filter is made in the USA from materials chosen for strength and chemical resistance. Stainless steel straps maintain clamp force under constant vibration and resist corrosion in harsh road environments. Molded polymer gaskets create a leak proof barrier against fuel and debris while hardware undergoes rigorous quality inspections for full traceability. This robust construction stands up to thermal cycling, road salt and daily driving challenges.
Engineered for precise fuel delivery and dependable operation in your LS swap, this kit ensures lasting confidence on the road.
