EFI Fuel Tank Kit for LS and LT Engine Swaps on 1970-1972 Oldsmobile Cutlass
When adapting an LS or LT engine into a 1970-1972 Cutlass chassis, maintaining a constant fuel supply during hard acceleration and cornering can make or break performance. This EFI fuel tank kit features a baffled interior and a 400 liter per hour pump to prevent starvation under 550 horsepower loads, and its shape mirrors factory mounts for a direct fit. Installers benefit from a complete hardware selection and clear instructions that guide each step and a leak resistant build engineered for lasting service. By preserving original ground clearance and eliminating the need for frame modifications, this kit streamlines the swap and reduces installation time.
Precision Engineered for Direct Chassis Integration
The tank housing follows the exact underbody contours of the 1970 to 1972 Cutlass frame rails to deliver a true direct fit without any cutting or welding. By matching factory mounting points, this design preserves original ground clearance and maintains proper exhaust and suspension clearance. Installers can simply set the unit in place, align the straps, and secure it with the supplied fasteners, eliminating adjustments and rework. This precision alignment also ensures consistent underbody flow characteristics and prevents interference with brake and fuel lines.
Advanced Baffled Tank Architecture for Fuel Stability
An internal network of partitions divides the tank volume into isolated chambers that dramatically reduce fuel movement during hard cornering, acceleration, or braking. This configuration keeps the pump pickup fully submerged at all times, preventing brief moments of fuel starvation that can lead to lean spikes under heavy load. As a result, throttle response remains crisp and engine operation stays stable even when producing more than 550 horsepower. By controlling fluid motion, the design safeguards against inconsistent air–fuel ratios and helps preserve pump life.
400 LPH Walbro Pump Module Optimized for High-Performance Applications
Central to this kit is a high-output 400 liter-per-hour Walbro pump engineered for supercharged or over-550 horsepower setups. Its precision impeller and internal module design deliver a steady stream of fuel under steep inclines and track day conditions, while quiet operation and vapor lock resistance ensure reliability in extreme scenarios. The in-tank configuration draws fuel effectively at any attitude, maintaining constant pressure to injectors for accurate metering. This robust solution supports aggressive EFI tuning and sustained high-load demands.
Comprehensive Hardware Package for Efficient Installation
This kit arrives complete with pump module, sending unit, filler neck, vent filter, tank straps, gaskets, and all necessary fasteners to streamline assembly. Each component is tailored to slot into factory openings with no alterations, and the straps cradle the tank to dampen movement and prevent wear. Clear, step by step instructions guide installers through proper torque values, leakproofing techniques, and system checks for a secure seal. The result is a reliable fuel system that minimizes fitment issues and accelerates project completion.
