EFI Fuel Tank for LS and LT Swaps in 1970-1972 Oldsmobile Cutlass
For projects fitting LS or LT engines into a 1970 to 1972 Oldsmobile Cutlass, dependable fuel delivery begins with a tank tailored to narrow frame rails and compact exhaust routing. The 1970 to 1972 Cutlass EFI Fuel Tank Kit with 400 liter per hour pump and notched shell offers a precise rear contour for tire and exhaust clearance while housing a high output Walbro module. Inside the tank, the pump assembly includes an integrated level sending unit, vent filter and filler neck. A complete hardware set of straps, gaskets and mounting brackets streamlines installation. Rated to support supercharged power above 550 horsepower, this kit retains factory suspension mounts and eliminates the need for chassis modification in your restoration or conversion.
Product Overview
The 1970-1972 Cutlass EFI Fuel Tank Kit delivers a complete solution for EFI conversions in Classic Oldsmobile Cutlass models. This all-in-one kit contains a notched steel tank, a high-output 400 LPH Walbro electric pump, mounting hardware, and a fuel level sending unit. Each component is specifically engineered for 1970-1972 Oldsmobile Cutlass EFI modifications, ensuring a seamless transition from carbureted to electronic fuel injection applications. By focusing solely on Cutlass fitment, the kit avoids fitment pitfalls common to generic tanks, giving installers confidence that every detail aligns with the vehicle's underbody contours and factory frame rails.
Notched Design and Clearance Benefits
The notched tank profile provides critical enhancements to exhaust routing and tire clearance in tight installation environments. By recessing the tank's center section, exhaust headers can run with improved spacing, reducing heat soak and minimizing interference with chassis components. This configuration also allows for more generous rear tire fitment without the risk of contact during suspension travel. When paired with MuscleRods mounting brackets, the tank's notch ensures consistent fuel line angles and frame alignment, preserving drivetrain geometry and preventing unwanted torque steer or binding under acceleration.
400 LPH Fuel Pump Performance
At the heart of this kit lies the Walbro 400 LPH electric pump, rated to support supercharged engine setups that exceed 550 horsepower. The pump delivers steady fuel pressure under high load, maintaining optimal injector flow even during sustained high RPM operation. Its robust design features internal baffling to reduce fuel slosh, preventing vapor lock in aggressive cornering or track use. The built-in fuel level sending unit offers precise tank level feedback, compatible with standard gauge clusters to keep drivers informed without additional adapters or aftermarket interfaces.
Installation and Compatibility
All installation hardware is included to facilitate a straightforward drop-in process. Clear instructions detail mounting point locations, wiring harness connections, and fuel line routing. Precision welding on the tank's seams ensures leak-free operation, and OE-style mounting points match the Cutlass frame rails without modification. Whether installing in a daily driver or a high-performance show build, this kit minimizes fabrication time. The focused design and dedicated support for Oldsmobile Cutlass EFI conversions make it an ideal upgrade for any enthusiast seeking reliable fuel delivery and exact fitment.
