1970-1972 Oldsmobile Cutlass A-Body LS and LT EFI Fuel Tank Kit with 400 LPH Pump
For anyone fitting a modern LS or LT engine into a 1970-1972 Oldsmobile Cutlass, precise fuel delivery begins with a tank designed to navigate narrow frame rails and tight exhaust routing. This 1970-1972 Cutlass EFI Fuel Tank Kit includes a notched rear contour matched to the A-Body chassis and a 400 LPH pump calibrated to support engines drawing up to 550 horsepower. By preserving factory mounting points, the shell avoids time consuming chassis work and keeps suspension geometry intact. Installers will appreciate the complete hardware set and integrated sending unit, which streamline installation and maintain accurate level readings under heavy cornering.
Precision Notched Tank Shape for Exhaust and Tire Clearance
The fuel tank shell features a precision cut notch at the rear to clear modern exhaust tubes and wide tires without altering the original A-Body frame rails. By preserving factory suspension mounting points, it retains stock ground clearance and handling traits under full jounce or hard cornering. This contour avoids metal-to-metal contact that can abrade tubing or sidewalls over time. Installers simply bolt the tank into existing bracket locations, eliminating complex chassis modifications and reducing hours spent on metal fabrication.
400 LPH Walbro Pump Delivers Robust Flow for Up to 550 HP
At the heart of this kit is a Walbro electric pump rated at 400 liters per hour, precisely calibrated to support LS and LT engines producing up to 550 horsepower or beyond. Its balanced rotor and housing design minimizes vibration and operational noise, while the high volume output sustains consistent fuel pressure during wide open throttle runs. This capacity all but prevents vapor lock and fuel starvation when power demand spikes, making it suitable for both forced induction systems and aggressive naturally aspirated builds that push the envelope on performance.
Integrated Fuel Level Sender for Stable Gauge Feedback
Incorporating the fuel level sensor directly into the pump module streamlines wiring and cuts potential leak points in the system. Positioned deep within the tank, the float assembly experiences less slosh impact, delivering precise gauge readings during acceleration, braking and lateral G loads. This single assembly design also keeps sensitive electronics shielded from underbody heat and vibration. Technicians benefit from a cleaner harness layout, while drivers gain confidence from accurate fuel data in all driving conditions.
Complete Installation Kit to Expedite 1970 to 1972 Cutlass EFI Swaps
This all in one kit arrives with every component needed for a straightforward LS or LT EFI conversion in a 1970 through 1972 Oldsmobile Cutlass. Included are the 400 LPH pump module with integrated sender, tank straps, a fill neck, vent filter, gaskets and mounting hardware. Each part is engineered for direct fit to the notched tank geometry and chassis brackets, so there is no guesswork sourcing adapters or fittings. By eliminating extra trips for missing parts, builders save valuable time and keep project timelines on track.
Count on this kit for reliable flow and precise fit in your LS or LT conversion. For a smaller capacity fuel pump kit at 255 LPH consider our 1970-1972 Cutlass 255 LPH pump Tank Kit (notched).
