400 LPH Walbro EFI Tank Stabilizes Fuel for 81-88 Cutlass LS LT

Engineered for seamless LS and LT engine conversions in 1981–1988 Cutlass models, the 400 LPH Walbro EFI Fuel Tank Kit delivers stable pressure under supercharged or over 550 hp loads with its high-pressure pump. Complete hardware and plug and play design ensure effortless installation while preventing fuel starvation for reliable acceleration and peak engine performance.

1981-1988 Oldsmobile Cutlass LS and LT EFI Fuel Tank Kit

When converting your 1981-1988 Oldsmobile Cutlass to LS or LT power, ensuring a constant fuel supply is essential and the EFI Fuel Tank Kit with its 400 LPH Walbro pump delivers precise pressure under high demand. All components, from the sending unit to the filler neck, bolt into factory mounting points and preserve original fuel line routing to minimize modifications. The complete hardware package allows shops and home builders to move through installation quickly and focus on tuning instead of sourcing parts. Continuous flow during spirited acceleration and long highway runs prevents fuel starvation when your build exceeds 550 horsepower.

Superior Fuel Flow with 400 LPH Walbro Pump

The heart of this tank kit is the 400 LPH Walbro pump, engineered to deliver a steady stream of fuel even when demand peaks. By sustaining consistent pressure, it eliminates lean spots during rapid throttle transitions and spirited acceleration. This level of reliability is crucial for electronic fuel injection setups, ensuring the engine always receives the correct mixture for smooth operation and maximum power. Whether you're on a long highway run or navigating backroad passes, the pump's unwavering performance prevents fuel starvation.

Precision Fit for LS and LT Engine Conversions

Every contour of the EFI fuel tank and its mounting hardware is crafted to match the factory points on 1981-1988 Oldsmobile Cutlass chassis. The sending unit and filler neck align exactly with original lines, preserving undercarriage integrity and avoiding major modifications. This precision engineering reduces installation time and ensures the swapped LS or LT engine retains proper fuel line routing. Technicians and home builders alike appreciate the plug and play alignment that maintains vehicle structure.

Comprehensive Hardware Package Streamlines Assembly

This kit arrives complete with all necessary parts: the in-tank pump module, sending unit, tank straps, filler neck, vent filter, gaskets, and all fasteners. By grouping these components into one shipment, builders avoid extra trips to parts suppliers and eliminate guesswork. The organized packaging of related hardware makes each assembly step intuitive, saving professional shops and enthusiasts valuable time on the garage floor.

Designed to Support Supercharged and High-Output Builds

Rated for applications over 550 horsepower, this fuel tank kit excels in high-stress environments such as forced-induction setups. Its internal design resists vapor lock and pump cavitation, delivering continuous flow during hard cornering and extended drives. Heat soak and fuel aeration are minimized, giving drivers the confidence to push their supercharged or boosted engines without worrying about drops in fuel pressure. The result is dependable delivery under all driving conditions.

Trust this fuel tank kit for steady delivery under all driving conditions. To complement your build or when a smaller capacity fuel pump kit at 255 LPH is preferred, consider our 1981-1988 Olds Cutlass EFI Fuel Tank Kit - 255 LPH Pump.
