LS and LT EFI Fuel Tank with 400 LPH Pump for 1970-1972 Oldsmobile Cutlass
When dropping an LS or LT engine into a 1970 to 1972 Oldsmobile Cutlass, securing reliable fuel delivery starts with a tank that fits without extensive chassis work. This EFI Fuel Tank Kit features a notched rear contour and 400 LPH pump to clear tube headers and oversized tires while leaving the factory frame rails intact. Precision engineered mounting straps and a built in sending unit streamline wiring and keep fuel level readings accurate under hard acceleration and heavy cornering. Installers will appreciate the complete hardware set that eliminates guesswork and accelerates project timelines.
Engineered Notched Tank Shape for Exhaust and Tire Clearance
This fuel tank shell features a precision-cut rear notch that carves out room for modern tube headers and wide tires without altering factory frame rails. By preserving the original A-Body suspension mounting points, it maintains stock ground clearance and handling characteristics under full jounce and deep cornering. The strategic contour avoids contact with exhaust tubing or sidewalls, preventing abrasive wear over time. Installers can simply bolt the tank into existing bracket locations, eliminating the need for complex chassis modifications or time-consuming metal work.
400 LPH Fuel Pump Ensuring Steady Flow Under Demand
At the heart of this kit is a pump calibrated to deliver 400 liters per hour, supplying LS and LT engines drawing up to 550 horsepower or more. Its balanced rotor and housing components minimize vibration and noise, while the high flow rate maintains consistent pressure during wide-open-throttle runs. This robust performance reduces the risk of vapor lock or fuel starvation when power demand spikes, supporting both supercharged setups and aggressive naturally aspirated builds without compromise.
Integrated Level Sender for Accurate Readings in Motion
Incorporating the fuel level sensor into the pump module streamlines wiring and cuts down on potential leak points. Positioned deep inside the tank, the float experiences less slosh impact, yielding precise gauge feedback during acceleration, braking and lateral loads. This single-assembly design also protects sensitive electronics from underbody heat and vibration. Technicians benefit from a cleaner harness layout and fewer connectors, while drivers enjoy reliable fuel-level data under every driving condition.
Complete Component Set Simplifying the Swap Process
This kit arrives ready for installation with all necessary parts matched to the 1970–1972 Oldsmobile Cutlass chassis. Included are the 400 LPH pump module with integrated sender, tank straps, filler neck, vent filter, gaskets and hardware. Each piece is engineered for direct fit alongside the notched tank geometry, so there’s no guesswork sourcing extra fittings or adapters. As a result, builders save valuable hours, avoid last-minute trips for missing parts and keep even complex LS and LT swap projects on schedule.
