1970-1972 Oldsmobile Cutlass EFI Fuel Tank Kit with 255 LPH Pump for LS Swap
For enthusiasts fitting an LS powerplant into a 1970 to 1972 Oldsmobile Cutlass this EFI tank kit provides all the fuel hardware needed to maintain stable pressure without trimming frame rails. The molded tank shape preserves original underbody clearances and nests securely in spot welded mounting pads for a direct fit on classic Cutlass chassis. Included stainless steel lines and a precision filler neck eliminate adapter work and resist corrosion under the vehicle. At its heart the 255 LPH Walbro pump supports up to 550 horsepower in both returnless and traditional systems.
Custom Molded Tank Profile for 1970–1972 Cutlass A Body Integration
The fuel tank features a precisely molded profile that mirrors the underbody contours of 1970 to 1972 Oldsmobile Cutlass A Body frames, preserving original rail clearances without any trimming or notching. By matching factory mounting pad geometry, the tank seats securely in spot welded pockets and locks into place with the stock strap locations. This attention to form ensures brake lines and fuel return tubes remain clear of suspension components and heat sources, reducing the risk of abrasion or thermal stress. Installers gain confidence knowing the fuel tank installs with millimeter accuracy and maintains chassis integrity over years of service.
Engineered 255 LPH Walbro Fuel Pump Ensuring Steady Flow
At the heart of this kit lies a 255 LPH Walbro fuel pump designed to support LS engines up to 550 horsepower without pressure dips under load. An internal bypass valve allows compatibility with both returnless and traditional rail setups, keeping flow consistent from idle to full throttle. The integrated strainer guard captures debris before it reaches the pump motor, reducing wear and preventing performance hiccups during sustained high demand. Built with winding patterns that resist heat soak, this pump retains peak output even after extended operation on road or track.
Integrated Stainless Steel Fuel Lines and Precision Filler Neck
A precision formed filler neck aligns with the factory opening to eliminate adapter fabrication or body modifications, while included stainless steel lines are bent to exact radii for smooth routing under the chassis. Choosing corrosion resistant steel removes additional fittings and reduces leak points, and the consistent tube bends prevent kinks or stress concentrations that could interrupt flow. A molded vent filter further safeguards against ingress of debris during tank breathing, ensuring reliable venting in both stationary and dynamic conditions. Together these features simplify installation and enhance long‐term durability.
Comprehensive Fuel Kit Simplifies LS Swap Installation
This all inclusive fuel tank kit arrives complete with the pump module, sending unit, filler neck, tank straps, gaskets, hardware and vent filter, covering every component needed for an LS conversion. Each part is engineered to work together and fit the 1970–1972 Cutlass A Body frame rails and body mounts, so builders can source all elements in one package and avoid delays. Detailed instructions walk through pump wiring, vent line routing and strap placement to ensure a fast and accurate assembly. Backed by USA manufacturing, the kit delivers consistent quality and a dependable fuel delivery system for high-output LS applications.
