1970-1972 Oldsmobile Cutlass EFI Fuel Tank Kit for LS and LT Swaps
Swapping an LS or LT powerplant into a 1970 to 1972 Oldsmobile Cutlass often exposes the stock tank's inability to sustain pressure under heavy throttle, which the 1970-1972 Cutlass EFI Fuel Tank Kit with 400 LPH pump and notched tank solves with a robust electric assembly. This EFI fuel tank kit pairs a 400 LPH Walbro pump with a custom notched tank design to clear headers and wider tires without cutting frame rails. It also integrates a sending unit and includes all gaskets, straps and fittings to simplify installation on the A Body chassis.
Notched Tank Geometry for Clear Exhaust Routing
The custom cut section at the rear of the tank carves out space for modern tube headers and wider tires without altering the original frame rails. This precise shaping preserves chassis integrity while eliminating clearance problems that arise during aggressive driving. By maintaining factory floor height, the design allows traditional suspension tuning and tire placement at the same height as a stock setup. Builders benefit from a plug and play solution that removes the need for metal fabrication or time consuming mock ups.
400 LPH Walbro Pump Ensures Steady Flow Under Load
At the heart of the assembly lies a 400 liter per hour Walbro electric pump that meets the steady fuel demands of LS and LT powerplants up to and beyond 550 horsepower. Its consistent spin rate delivers stable pressure under wide open throttle and during washboard cornering, effectively preventing vapor lock and fuel starvation. The pump's proven internal design also promotes quiet operation and long service life, making it an ideal choice for both street and track use. Technicians and drivers alike can rely on uniform fuel delivery when the engine is pushed to its limits.
Integrated Sending Unit Provides Reliable Fuel Level Monitoring
The fuel level sender resides within the pump module to reduce harness length and shield sensitive wiring from vibration and heat. This integration yields more accurate gauge readings by minimizing slosh induced errors when cornering or braking hard. Installers appreciate the reduced component count, while drivers gain confidence in uninterrupted monitoring of their fuel reserves. The result is a cleaner engine bay with fewer exposed connectors and a straightforward wiring path back to the dashboard.
Complete Kit Design Simplifies A Body Fuel System Upgrade
Every fitting and strap needed for the 1970 to 1972 Oldsmobile Cutlass A Body is included, from the filler neck and vent filter to tank straps, gaskets and brackets. This cohesive package removes the guesswork of sourcing matched components and ensures each part aligns perfectly from the first bolt. Installers save hours that would otherwise be spent tracking down hard to find hardware. The outcome is a seamless swap that keeps the build timeline on track and avoids last minute compatibility issues.
