EFI Fuel Tank Kit with 255 LPH Pump for LS Swap in 1978-1987 Oldsmobile Cutlass
For a Cutlass four door from 1978 through 1987 this EFI Fuel Tank kit with 255 LPH Pump provides the reliable supply needed for an LS engine swap. It installs into the factory cavity on stock mounts and retains the original filler neck for accurate level sensing and full underbody clearance. A brushless 255 LPH pump delivers steady flow for engines up to 550 hp and the modular cartridge lets builders step up to 400 LPH without new brackets or wiring. All straps seals and fittings are made in the USA to ensure lasting performance.
Brushless 255 LPH Pump Ensuring Stable LS Fuel Pressure
This EFI tank kit features a brushless 255 LPH pump that delivers consistent pressure and volume for LS engines up to 550 hp. The absence of brushes reduces internal wear and minimizes heat buildup during extended runs, while a balanced rotor and fully sealed housing protect against vibration and moisture intrusion. This design prevents cavitation at high engine loads and maintains constant fuel supply even under aggressive throttle inputs. The smooth delivery curve ensures no dips in pressure, keeping the engine responsive throughout the entire rev range.
Quick Capacity Upgrade via Modular Pump Cartridge
The modular pump cartridge system lets you swap the standard unit for a 400 LPH version without altering brackets or rewiring harnesses. Simply remove the existing module and insert the higher capacity cartridge in minutes-no cutting, drilling, or special tools required. Factory sealing rings preserve leak free operation after each change, and the original port alignments remain intact to protect surrounding tank components. This adaptability means you can keep pace with forced induction setups or aggressive cam profiles as horsepower demands evolve.
OEM Tank Integration for 1978 to 1987 Cutlass EFI Installations
Designed to install directly into the stock tank cavity of 1978 through 1987 Cutlass four door models, this assembly uses the original mounting points for a secure, factory style fit. Retaining the OEM filler neck preserves underbody clearance and ensures the factory level sensor functions with full accuracy. The sending unit arrives prewired to plug into the existing harness, eliminating the need for extension leads or adapter blocks. By matching factory dimensions, the system avoids interference with exhaust routing and chassis components.
American Made Straps Seals and Filters for Enduring Protection
Every strap, seal and fitting in this kit is produced in the USA from corrosion resistant materials selected specifically for fuel contact and engine bay vibration. Stainless steel straps maintain consistent clamp force over time, while molded polymer gaskets create a tight barrier against leaks and debris. The in tank vent filter captures contaminants before they reach the pump, and all hardware undergoes rigorous inspection with full traceability. This collection of domestic parts endures thermal cycles and daily driving conditions without compromise.
Engineered for precise fit and reliable fuel delivery for your LS swap.
