1978-1980 Oldsmobile Cutlass LS EFI Fuel Tank Kit with 255 LPH Pump
Swapping an LS engine into a 1978 to 1980 Cutlass Notchback demands dependable fuel flow under every driving condition. This EFI fuel tank kit with 255 LPH pump directly replaces the stock container and secures to the frame using original mounts, eliminating modification work. Precision machined vent fittings and rugged gaskets seal around the filler neck to quell vapor loss while preserving the underbody profile. A 255 LPH Walbro pump within the corrosion resistant module sustains consistent pressure to support engines up to 550 hp without lean spots during acceleration or sustained loads.
Integrated In Tank Fuel Module Design
The Cutlass Notchback kit unites the 255 liter per hour Walbro pump, sending unit and prefilter in one corrosion resistant housing that resists ethanol blends and road moisture. Internal vibration mounts cushion wiring and seals against engine motion, lowering the risk of wear and leaks. By consolidating these functions into a removable assembly, routine inspection or part replacement can be done quickly with minimal tank handling. This modular approach cuts down service time and enhances reliability over conventional retrofit modules.
Precision Sealing with Machined Vent Filters and Gaskets
Each vent filter is machined to match the original filler neck shape, achieving a tight seal that keeps dirt out and controls vapor release. Elastomer gaskets maintain even compression through repeated refills and temperature changes, preventing fuel vapor from escaping into the chassis. Because these parts lock in place around the factory tank geometry, there is no need for custom adjustments or shimming. This design preserves the underbody profile and meets evaporation control standards without compromise.
Consistent Fuel Flow for 550 Horsepower LS Engines
With a calibrated flow rate of 255 liters per hour the module reliably supports LS engines up to 550 horsepower without lean spots under rapid throttle transitions or sustained loads. A balanced rotor and efficient motor design keep operating temperature low and noise levels down during extended use. Optimized internal passages help prevent air lock, ensuring continuous fuel delivery at all engine speeds. This ensures smooth driver response from idle through full boost and sustained highway cruising.
Straightforward Bolt In Frame Mount Installation
The entire fuel module bolts directly to the factory tank straps and frame brackets without cutting, welding or drilling, preserving the original undercarriage layout. A plug and play wiring harness connects pump, sending unit and ground points without splicing, ensuring correct polarity and easy diagnostics. All required hardware, including straps, mounting bolts, filler neck and sealing components, arrives in a single package to simplify inventory management. This true bolt in solution saves hours compared with custom fuel system builds.
