Steady Fuel Pressure for 1978-1980 Cutlass LS LT Builds

Optimized for 1978 through 1980 Oldsmobile Cutlass conversions, the 400 LPH EFI Fuel Tank Kit delivers consistent pressure under demanding supercharged or 550+ hp LS and LT engine loads by pairing a precision tested steel reservoir with a high-flow Walbro pump. All necessary fittings and hardware arrive in one box to minimize installation time and ensure durable operation for years to come.

1978-1980 Oldsmobile Cutlass EFI Fuel Tank Kit for LS and LT Engines

Retrofitting an LS or LT powerplant into a 1978 to 1980 Cutlass Notchback demands a fuel delivery solution built for sustained high rpm pull. This EFI fuel tank kit incorporates a 400 LPH Walbro pump matched to a precise sending unit and vent filter to maintain stable pressure under load. Every component installs in the factory tank location without modification and connects directly to standard LS and LT harness connectors for a true plug and play fit. Molded gaskets and heavy gauge steel straps secure the assembly and resist corrosion, letting you complete the swap quickly while relying on consistent performance from cruising to full throttle.

Consistent High Volume Fuel Delivery for LS and LT Engines

The core of this fuel tank kit is the 400 LPH Walbro pump, engineered to meet the demands of supercharged and 550 hp engine combinations. High volume flow is critical during rapid throttle transitions and extended wide open throttle runs to prevent lean conditions that can damage internal components. Precision-tested internals maintain steady output under load, ensuring the engine's calibration stays within safe operating parameters. By delivering uniform pressure from cruising to peak rpm, the system supports both daily driving and track sessions without compromise.

Seamless Fitment within Original Cutlass Tank Location

Every component is tailored to reinstall into the factory tank position, preserving the Cutlass notchback's stock clearance and appearance. The sending unit and vent filter align with the existing opening and attach to standard LS and LT harness connectors for true plug and play integration. Tank straps and filler neck match factory mounting points, eliminating the need for custom brackets or cutting. This precision fit approach greatly reduces bench labor and ensures a clean installation that maintains the vehicle's restoration quality.

Integrated Module Design Streamlines Installation

Rather than sourcing parts separately, this all-in-one kit groups the pump, module housing, sending unit, tank straps, filler neck, vent filter, molded gaskets and hardware into a single package. Each gasket is formed to seal reliably against fuel pressure and vibration, preventing leaks and vapor escape. The vent filter facilitates proper tank breathing and helps avoid vapor lock during hard acceleration or high ambient temperatures. With every critical element included, you save time and eliminate the risk of missing parts during your swap project.

Robust Durability and Ethanol Resistant Components

Durability testing under repeated flow and pressure cycles confirms reliable operation over long runs and varying conditions. Steel tank straps feature corrosion resistant coatings to withstand road moisture and ethanol fuel blends, while internal pump components are quality checked to factory grade standards. By validating each fitting, seal and housing against ethanol exposure, the kit delivers stable performance without the failures often seen in converted stock systems. This focus on rugged construction means fewer repairs and confidence in every drive.

To support lighter flow requirements with a smaller capacity fuel pump Kit at 255 LPH see our 1978-1980 Cutlass Notchback EFI Fuel Tank Kit - 255 LPH Pump. Count on MuscleRods quality for consistent results.
