1978-1980 Oldsmobile Cutlass EFI Fuel Tank Kit for LS and LT Swaps
Swapping an LS or LT engine into a 1978 to 1980 Cutlass Notchback puts new demands on fuel delivery, especially under high rpm and heavy load. This EFI fuel tank kit addresses those demands with a 400 LPH Walbro pump matched to a calibrated sending unit and vent filter for consistent pressure. All parts fit into the original tank location and plug into standard LS/LT harness connectors, preserving factory clearance and simplifying wiring. Precision molded gaskets and sturdy tank straps round out the package, cutting bench time and ensuring dependable performance on every drive.
Engineered Fuel Delivery for Demanding LS and LT Applications
The heart of this kit is the 400 LPH Walbro pump, designed to support supercharged or 550 plus hp setups without pressure drop during hard acceleration. High volume flow is essential under heavy load and rapid throttle changes to prevent lean conditions that can harm engine internals. Precision-tested internals maintain consistent output, ensuring your engine receives the exact fuel supply its tuning expects. This level of delivery stability keeps performance steady from cruising to full throttle.
Plug and Play Integration into Cutlass Notchback Chassis
Every component fits into the factory tank location with no cutting or modification required, preserving the Cutlass notchback's original appearance and clearance. The calibrated sending unit and vent filter install directly in the stock opening and snap into standard LS/LT harness connectors for a true plug and play experience. Tank straps and filler neck match the vehicle's bracket points, eliminating the need for fabrication. This purposeful fitment approach cuts installation time and minimizes fitment headaches.
Comprehensive Tank Kit with Precision Matched Components
Beyond the high flow pump, the kit bundles a calibrated sending unit, sturdy tank straps, precision molded gaskets, a contoured filler neck, vent filter and all required hardware for a complete solution. Each gasket is molded to seal reliably under fuel pressure and road vibration, preventing leaks and vapor loss. The vent filter promotes proper tank breathing, reducing vapor lock risk. By offering all critical parts in one package, the kit moves your project forward without last-minute trips for missing pieces.
Validated Durability for Consistent Operation
Components undergo rigorous flow and pressure cycle testing to verify leak free performance over time. Metal parts feature corrosion resistant finishes to stand up to ethanol blends and environmental exposure. The pump module, sending unit and fittings are quality checked to ensure they meet factory grade standards for long term use. These validation steps deliver a fuel system you can count on day in and day out, whether on the street or at the track.
