Reliable 400 LPH Fuel Delivery for 1978-1980 Oldsmobile Cutlass LS LT

Optimized for supercharged and 550 plus hp demands, the 1978 to 1980 Cutlass Notchback EFI Fuel Tank Kit pairs a 400 LPH Walbro pump with a precision tested steel reservoir to deliver unwavering pressure throughout your LS and LT conversion. Complete with all fittings, hardware and a rugged assembled module, it ensures streamlined installation, sustained durability and consistent fuel flow for peak performance in any era correct Cutlass build.

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

Every LS or LT engine swap in a 1978 through 1980 Cutlass Notchback requires a fuel solution that holds pressure across rapid throttle transitions and sustained high rpm runs. The kit uses a 400 LPH Walbro pump mated to a precise sending unit and vent filter, all housed within the factory tank location and ready for direct connection to LS and LT harness plugs. Molded gaskets and heavy gauge straps secure the assembly without cutting or modifications to original mounts. Endurance testing against ethanol blends and repeated flow cycles confirms reliable operation for both daily driving and track sessions.

Walbro Pump Module Optimized for LS and LT Performance

The beating heart of this kit is the 400 LPH Walbro fuel pump, chosen for its continuous duty design and capacity to support both supercharged applications and naturally aspirated engines exceeding 550 horsepower. Engineered with high tolerance components, the pump delivers a consistently stable flow rate during sudden throttle applications and extended wide open throttle sessions, which helps eliminate lean condition risks that can lead to detonation or component fatigue. In bench testing, the unit demonstrates minimal output variance under thermal stress, ensuring that the engine calibration remains within safe parameters from idle to peak rpm. Its electric motor and impeller assembly have been selected to resist pressure drop at high engine speeds, maintaining uniform delivery even under heavy load. By integrating this pump into the module housing, users benefit from a pre-assembled solution that aligns with LS and LT fuel system expectations. This emphasis on precision flow control makes the module an essential component for preserving engine health during spirited driving and track use.

Direct Fitment with Factory Tank Mounts and Standard Harness Connections

Installation is streamlined by designing each component to fit perfectly into the original Cutlass Notchback tank position, eliminating the need for cutting or welding that can jeopardize sheet metal integrity. The sending unit and vent filter are dimensioned to align precisely with factory openings and connect seamlessly to standard LS and LT harness plugs, delivering true plug and play functionality. Heavy gauge steel straps supplied in the kit mirror the factory strap profile and include corrosion resistant coatings, ensuring long-term security and resistance to road moisture. Molded gaskets are formed from fuel resistant polymers to maintain a reliable seal against vibration, thermal cycling and pressure fluctuations, preventing leaks and vapor intrusion. This precision fitment approach expedites bench work and reduces potential errors, allowing builders to maintain the vehicle's original appearance and structural alignment. By preserving the factory mounting points, this solution supports ongoing restorations without compromise.

Comprehensive Fuel Assembly Built for Ethanol Compatibility and Reliability

Beyond just a pump and a sending unit, this fuel tank kit arrives complete with filler neck, vent filter, molded gaskets and all necessary mounting hardware, offering a ready to install solution for LS or LT engine swaps. Each seal and fitting undergoes evaluation under ethanol fuel blends to verify chemical resistance, ensuring that long term exposure to modern pump fuels does not degrade performance or cause seal failure. The vent filter included in the assembly facilitates proper tank breathing, maintaining equilibrium between internal pressure and ambient conditions to prevent vapor lock during hard acceleration or high temperature episodes. All hardware components are zinc plated or coated to resist corrosion from moisture and road contaminants, extending service life and reducing maintenance intervals. This integrated module reduces the risk of missing or incompatible parts during installation, while also simplifying troubleshooting by consolidating critical elements into a single, factory style package. The attention to compatibility and durability means users achieve consistent fuel pressure and flow from daily commutes through demanding performance drives.

For a smaller capacity fuel pump kit at 255 LPH consider our 1978-1980 Cutlass Notchback EFI Fuel Tank Kit - 255 LPH Pump for consistent pressure under demanding engine speeds.
