LS EFI Fuel Tank Kit for 1970-1972 Oldsmobile Cutlass A-Body
When converting a 1970 to 1972 Oldsmobile Cutlass to EFI, securing a dependable fuel supply becomes essential and this EFI Fuel Tank Kit delivers with a 255 LPH Walbro pump and all necessary hardware for a direct fit. It maintains factory rail clearances by replicating the original tank pad geometry and includes molded stainless steel lines plus a precision formed filler neck to integrate with custom fuel setups. Consistent fuel pressure is assured under heavy load thanks to the built-in bypass valve and internal strainer, so injectors receive steady flow across idle and wide open throttle conditions.
Tailored Fit for 1970 to 1972 Cutlass Frame Rails
This fuel tank kit is shaped to match the underbody contours of 1970 to 1972 Oldsmobile Cutlass models, preserving factory clearances along the frame rails. By replicating original mounting pad geometry, it enables a direct installation without trimming or notch work. The precise alignment with suspension hangers and chassis crossmembers reduces the need for trial fitting and protects structural components from unintended stress. Installers can rely on consistent strap locations and filler neck position, ensuring the tank sits exactly where the stock unit did. This attention to form factor simplifies the transition from carbureted to EFI systems while maintaining the vehicle's original clearance envelope.
Engineering of the 255 LPH Pump for Consistent Pressure
The heart of this kit is a 255 LPH Walbro pump designed to support LS engines producing up to 550 horsepower. Its internal bypass valve regulates returnless systems and traditional return designs, keeping fuel rail readings steady from idle through wide open throttle. An integrated strainer captures debris before it can enter the pump motor, while the winding design resists heat soak during extended operation on the road or track. This combination of flow capacity and pressure control prevents lean conditions under load and supports optimized injector performance. The result is a fuel supply that responds predictably to rapid changes in engine demand.
Precision Filler Neck and Stainless Line Integration
A precision formed filler neck ensures a seamless interface with both original sheetmetal openings and aftermarket body modifications. Its contour mirrors factory dimensions, so no additional cutting or casting is required. The included stainless steel lines mate directly to the tank outlets, providing corrosion resistance and mechanical strength for custom routing under the vehicle. This material choice eliminates the need for secondary adapters or hose assemblies, reducing potential leak points. In concert with the molded vent filter, the system offers dependable sealing and smooth flow into remote fuel setups.
Comprehensive Kit Streamlines LS Swap Installation
Everything needed for the fuel delivery portion of an LS conversion arrives in one package, cutting parts sourcing to a single step. Alongside the pump and sending unit are tank straps, gaskets, vent filter, hardware, and a direct fit filler neck. Clear instructions guide users through each connection and mounting point, minimizing guesswork even for those tackling their first fuel tank project. By combining precision components in a single kit, the build process moves faster and requires fewer alignment checks. The outcome is a reliable EFI fuel system ready for high output use.
