1978-1980 Oldsmobile Cutlass LS EFI Fuel Tank Kit with 255 LPH Pump
When you're swapping an LS engine into a 1978-1980 Oldsmobile Cutlass Notchback, ensuring a reliable fuel supply becomes critical and this EFI fuel tank kit addresses that need with a direct fit solution. By pairing the original steel tank with a 255 LPH Walbro pump this kit delivers consistent volume under load and prevents fuel starvation during hard acceleration. Installation into factory mounting points keeps the chassis unchanged and speeds fitting time for both street machines and track cars. The system supports LS builds up to 550 horsepower while maintaining steady pressure across all driving conditions.
Seamless Integration with Cutlass Notchback Chassis
The EFI fuel tank kit is engineered to match the factory mounting points on a 1978–1980 Oldsmobile Cutlass Notchback, allowing the original body shape to remain unchanged. Precision machined components such as the filler neck, vent filter and tank straps contour exactly to the underbody profile, eliminating the need for cutting or welding. This attention to fitment not only preserves the car's classic appearance but also cuts installation time by removing fabrication steps. Builders benefit from a plug-and-play experience that keeps the chassis in its stock configuration while delivering modern EFI capability.
Durable In Tank Module for Reliable Operation
The heart of the system is a robust in tank assembly that houses the pump, sending unit and filter media in a single corrosion resistant module. Vibration control features dampen harmonic stresses, protecting electrical connections and internal seals under sustained highway use or track duty. Included gaskets and hardware are selected for fuel resistance and precise sealing to prevent leaks over many cycles of fill and drain. This design simplifies maintenance by keeping all critical components accessible as one serviceable unit.
Consistent Fuel Delivery for High Demand LS Engines
The 255 LPH Walbro pump is matched to support LS engine outputs up to 550 horsepower, supplying a steady volume of fuel under rapid throttle transitions and sustained boost conditions. By maintaining precise flow rates at peak demand, the system prevents lean spots or hesitation that can compromise performance or engine health. Users will notice crisper acceleration response and uniform power delivery across the entire rev band. Whether on the street or at the track, this pump capacity ensures the LS conversion operates with confidence under all driving scenarios.
