LS and LT EFI Fuel Tank Kit for 1970-1972 Oldsmobile Cutlass
When an LS or LT powerplant is dropped into a 1970-1972 Oldsmobile Cutlass, stock tanks struggle to clear modern headers and keep fuel pressure under hard acceleration, which this EFI Fuel Tank Kit with a 400 LPH pump fixes effortlessly. Featuring a notched tank design, it carves room for wider tires and tube headers without altering the A-Body frame. With its integrated sending unit and complete hardware set including gaskets, straps and fittings, installers get accurate fuel level readings and can finish the swap without chasing parts.
Notched Tank Geometry for Improved Exhaust and Tire Clearance
The custom notch cut into the rear section of the tank creates vital space for modern tube headers and wider tires without any frame rail alterations. This careful shaping retains original floor height so suspension dynamics remain unchanged, allowing builders to use factory mounting points and geometry. By avoiding interference at full suspension travel or under heavy cornering loads, the design prevents rubbing or abrasion on header tubes and tire sidewalls. Installers benefit from a direct fit solution that reduces mock ups and metal work, speeding up the installation process.
400 LPH Walbro Pump Delivery for High Demand Fueling
At the core of the assembly sits a 400 LPH Walbro electric pump engineered to support LS and LT powerplants up to 550 horsepower or more. Its high flow capacity ensures stable fuel pressure under wide open throttle and aggressive driving maneuvers, preventing vapor lock and starvation even when engine demands spike. The pump's internal construction promotes smooth operation with minimal noise and vibration, translating into reliable performance over many duty cycles. Drivers can push their builds on both street and track with confidence that fuel rates will remain uniform.
Integrated Sender Module for Stable Fuel Level Feedback
The fuel level sending unit is housed within the pump module to shorten wiring runs and shield sensitive electronics from heat and vibration. This integration reduces signal distortion caused by fuel slosh when accelerating, braking, or cornering, delivering more precise gauge readings on the dash. Technicians gain the advantage of fewer connectors and a tidier harness layout, while drivers appreciate consistent monitoring of the remaining fuel. Ultimately, this design choice simplifies routing and minimizes potential points of failure in the fuel circuit.
All Included Components for Simplified A Body Installation
This kit bundles every part needed for a complete A Body fuel system overhaul in one package, from the filler neck and vent filter to straps, gaskets, and hardware. By providing matched components, it eliminates the need to track down individual pieces or adapt mismatched fittings, reducing trial and error during assembly. Installers save hours that would otherwise be spent sourcing hard to find items, ensuring each element aligns precisely from the first bolt. The result is a streamlined swap that keeps build timelines on schedule and avoids last minute compatibility headaches.
